Sample Handling System of Mars 2020 Perseverance Rover

Turret of the Mars 2020 Perseverance Rover

The Mars 2020 Perseverance Rover‘s turret is located at the end of the 2.1-meter-long, 5-degree-freedom robotic arm. It carries the science instruments SHERLOC, WASTON, and PIXL to help with the sample handling process. Besides the three instruments, there are also the gDRT(Gaseous Dust Removal Tool) and the Corer. The Corer is positioned in the middle of the instruments. SHERLOC and WASTON are by one side of the Corer, while gDRT and PIXL are on the opposite side of the Corer. Collectively, they form the Mars 2020 Perseverance Rover‘s turret assembly. Our 1:2 Perseverance Mars Rover Replica will perfectly replicate the structure appearance of the Turret including the SHERLOC, WASTON, and PIXL instruments, the gDRT, and the Corer. 

The Mars 2020 Perseverance Rover‘s SHERLOC, WATSON, and PIXL instruments are introduced in more detail in [PIXL of the Mars 2020 Perseverance Rover Part 1], [PIXL of the Mars 2020 Perseverance Rover Part 2], [SHERLOC of the Mars 2020 Perseverance Rover], and [WATSON of the Mars 2020 Perseverance Rover]. With these scientific instruments the Mars 2020 Perseverance Rover‘s turret carries, the Mars 2020 Perseverance Rover is able to analyze the minerals and chemicals to study whether or not there was life or if it will be possible for humans to live on Mars by carefully and scientifically selecting the most valuable rock and soil samples to collect. Our Perseverance Mars Rover Replica‘s PIXL and the tools on it won’t have the functions as the real Mars 2020 Perseverance Rover, but the Perseverance Mars Rover Replica‘s PIXL replica will stimulate the movement when operating.  

After the Mars 2020 Perseverance Rover‘s robotic arm accurately transports the turret assembly to the location of interest, depending on what this specific mission’s purpose is, the corer will get one of the bits and will do an initial abrading operation. The Mars 2020 Perseverance Rover‘s turret then will rotate and find a position for gDRT to remove dust from the surface to prevent contamination preparing for the sample caching process. The gDRT is a sophisticated tool that consists of the following 7 components:

1. A supply tank with 159g of gaseous Nitrogen

2. A gas tank, or plenum tank which fills gas before every operation

3. Two supplementary supply valves for transferring gas from the supply tank to the plenum tank

4. A valve that releases the plenum tank’s gas

5. A nozzle that will blow the gas to the target surface

6. A valve that acts as the supply tank’s switch for releasing and loading gas before launch

7. A pressure transducer for the pressure reading

In the end, the Mars 2020 Perseverance Rover‘s turret will rotate to positions to allow SHERLOC, WASTON, and PIXL to work.

Our 1:2 Perseverance Mars Rover Replica will perfectly replicate the appearance structure of the gDRT down to very fine details, but it will not have the dust-removing function or the many components. 

Other than the mentioned tools, the Mars 2020 Perseverance Rover‘s turret assembly carries a sensor, the Ground Contact Sensor. The Ground Contact Sensor’s job is to prevent the Mars 2020 Perseverance Rover‘s turret from accidentally touching the ground by giving the robotic arm signals to stop if the turret gets too close to the ground. Our Perseverance Mars Rover Replica will perfectly replicate the appearance structure of Ground Contact Sensor but it will not actually be a sensor.

1:2 Perseverance Mars Rover Replica

After doing some tests in the physical world, we decided to upgrade the size of the Perseverance Mars Rover Replica from 1:3 to 1:2, and therefore the static Perseverance Mars Rover replica will be upgraded from 1:4 to 1:3.

The original dimensions of the body box of the Mars 2020 Perseverance Rover are as follows.

  • Length 10 feet (3 meters)
  • Width 9 feet (2.7 meters)
  • Height 7 feet (2.2 meters)

Therefore, the dimensions of the body box of the 1:2 Perseverance Mars Rover Replica are as follows.

Science Instrument of Mars 2020 Perseverance Rover

RIMFAX of the Mars 2020 Perseverance Rover

The Mars 2020 Perseverance Rover‘s RIMFAX is short for the Radar Imager for Mars’ Subsurface Experiment. It is a frequency modulated continuous wave radar. The Mars 2020 Perseverance Rover‘s RIMFAX has a mass of 3 kg, or around 6.6 lbs with a dimension of 7 inches by 4.7 inches by 2.4 inches, or 196cm by 120cm by 66cm. For our 1:2 Perseverance Mars Rover Replica, the dimension of the RIMFAX will be 3.5 inches by 2.35 inches by 1.2 inches, or 98cm by 60cm by 33cm.

The Mars 2020 Perseverance Rover‘s RIMFAX has two main components: the antenna and the electronic unit (EU). The RIMFAX’s radar antenna is located on the lower back rear of the Mars 2020 Perseverance Rover and facing down the cold ground. With a frequency range from 150 to 1200 MHz, the vertical resolution theoretically can go from 3 inches to 12 inches, or 15 cm to 30 cm, thick. Our Perseverance Mars Rover Replica will perfectly the appearance structure of the antenna but it will not the actual function that the real Mars 2020 Perseverance Rover‘s RIMFAX’s antenna has. 

The Mars 2020 Perseverance Rover‘s RIMFAX’s EU is located inside of the Mars 2020 Perseverance Rover’s left aft tower. The environment of the EU is thermally controlled, unlike the antenna. Since this is the first radar ever sent to Mars by NASA, the underground composition is unknown. Therefore, the RIMFAX is designed to be programable after each sounding is taken. EU has three components: the DC/DC converter board, data control board, and RF(radio frequency) analog board. Because the Mars 2020 Perseverance Rover‘s RIMFAX’s EU is inside of the body structure, and you cannot really see it from the outside, we might not replicate it for our Perseverance Mars Rover Replica, or we might replicate it after everything else is completed.  

Unlike the Mars 2020 Perseverance Rover‘s MOXIE, which consumes around 30% of the Perseverance Mars Rover’s power each time it runs, the Mars 2020 Perseverance Rover‘s RIMFAX only consumes around 5W for a normal traverse. It has two states: idle and sounding. When in the idle state, RIMFAX only communicates and receives signals. When RIMFAX is set to the sounding state, the power supply is then switched on and RIMFAX will start working. Our 1:2 Perseverance Mars Rover Replica‘ RIMFAX does not have the actual function like the real Mars 2020 Perseverance Rover‘s RIMFAX, but we may design it so that it will have other functions such as being able to light up in the dark. Therefore, Perseverance Mars Rover Replica‘ RIMFAX might also consume power.  

The Mars 2020 Perseverance Rover‘s RIMFAX will image the shallow surface under the Martian surface while the Mars 2020 Perseverance Rover is traveling with an interval of 4 inches, or 10 cm to provide information about the subsurface composition of the site. By penetrating the ground surface, the Mars 2020 Perseverance Rover‘s RIMFAX is able to detect ice, water, or salty water (brines) with a depth of over 30 feet, or 10 meters, but with a subsurface condition that is very good for radar wave propagation, the soundings can go deeper than 30 feet. Studying what’s beneath the Martian surface can help discover Mars’ past life (if there was any), past waters, past rock formation, and many other materials underneath the surface of the red planet.

Mars 2020 Perseverance Rover’s Ingenuity Helicopter Spends the Night by itself for the First Time

While the Mars 2020 Perseverance Rover is performing all the system checks, the Ingenuity Helicopter is also doing its part of the jobs. Giving the low temperature on Mars (it could go down below 90°C at night), keeping all the electronic systems and its mechanical structure warm is crucial. That is why when the Mars 2020 Perseverance Rover first arrived, the Ingenuity Helicopter stayed attached to the belly of the Mars 2020 Perseverance Rover till it was sufficiently charged from the Mars 2020 Perseverance Rover. Even after the Ingenuity Helicopter disengaged from the Mars 2020 Perseverance Rover it still carries backup batteries that were charged from the Mars 2020 Perseverance Rover.

We are building a 1:2 Peseverance Mars Rover Replica, which will perfectly replicate the appearance structure of the real Mars 2020 Perseverance Rover in very fine details, but with no actual scientific functions. The Ingenuity Helicopter is also in our plan to replicate. The difference between our Mars Rover Replica and Ingenuity Helicopter replica, on Earth, and the real Mars 2020 Perseverance Rover and Ingenuity Helicopter, on Mars, is we won’t need to keep them warm the whole time. The motors won’t run so heavily so you won’t need to worry about keeping them cool either.

After parting with the Mars 2020 Perseverance Rover, the rover moved far from the Ingenuity Helicopter so that Ingenuity would receive enough solar power. That is why the first night on its own would be very important, which is one of the milestones set for the Ingenuity Helicopter.

The Mars 2020 Perseverance Rover mainly runs on nuclear power, and the Ingenuity Helicopter runs on solar power, but for our Mars Rover Replica and the Ingenuity Helicopter replica, they will run on rechargeable batteries and an external power supply.

Unlike the Mars 2020 Perseverance Rover, the Ingenuity Helicopter does not carry any science instruments and its purpose on this mission is not for scientific study, but to only show the possibility of exploring a planet with an aircraft, even though it is a small one. It is beyond excitement that the Ingenuity Helicopter spent the first night on its own successfully. Now the team will prepare for the first flight.

Just like the Ingenuity Helicopter, our Mars Rover Replica also doesn’t carry any science instruments either, but our Mars Rover Replica will have all the scientific instruments’ appearance structures. If you are interested in our Mars Rover Replica, please check [1:2 Perseverance Mars Rover Replica Design and Building Diary].

MOXIE of the Mars 2020 Perseverance Rover – part 2

Even though the Mars 2020 Perseverance Rover itself cost around 2.7 billion dollars to build, the value MOXIE will produce and the experiences that will be gained are far more than that. As mentioned before, the Mars 2020 Perseverance Rover‘s MOXIE’s goal is not only to make oxygen for humans to breathe but also potentially to help with burning rocket fuel. This ensures that astronauts can come back to Earth from Mars (if human exploration on Mars becomes possible one day). Oxygen tanks are always the heaviest items on a spacecraft. If the Mars 2020 Perseverance Rover‘s MOXIE is successful and scientists can see that in the future more and larger MOXIE instruments will make enough oxygen on Mars and store it into tanks, it will save countless resources and money for space missions.

The Mars 2020 Perseverance Rover‘s MOXIE can produce oxygen at a rate of up to 10 g/h. To make it more realizable for us, this can support a puppy to live. But for humans, we will need the rate to go up to 20 to 30 g/h. For the time being, it only runs for one hour each time as instructed. The Mars 2020 Perseverance Rover‘s MOXIE is only a prototype to run trial tests to make oxygen. In the future, around 20 years from now, a full-size MOXIE is expected to be built for Mars human exploration missions, and the oxygen rate will be needed is around 2000 to 3000 g/h, which is about 200 times more than the MOXIE on Mars 2020 Perseverance Rover can so now. Even though MOXIE now cannot produce a big amount of oxygen due to lack of sufficient space and power, nor can it store the oxygen produced, needless to say, this is a necessary start.

There are three main components for the Mars 2020 Perseverance Rover‘s MOXIE: sensor panel assembly, scroll compressor, and the SOXE(Solid Oxide Electrolyzer) assembly. MOXIE will collect carbon dioxide from the Martian atmosphere and then get rid of the unwanted particles by a filter. We might or might not make the MOXIE replica for our 1:2 Perseverance Mars Rover

Since the Martian atmosphere is around 170 times thinner compared to Earth, if letting the air at ambient pressure enter the reactive core, it won’t make enough oxygen. Therefore, the Mars 2020 Perseverance Rover‘s MOXIE will need to compress the air by itself in order to have a high carbon dioxide density. The compressor will compress the filtered air to a pressure level similar to Earth’s pressure. Then a process called electrolysis will split the carbon dioxide into oxygen and carbon monoxide by heat and electricity at 800 Celsius, or 1472 Fahrenheit. At the same time, since the electrochemical reaction is running at such a high temperature, a very sophisticated insulating system is protecting all the equipment from being damaged by the heat. The final step is to measure the amount, the purity of the oxygen and calculate the efficiency of the system before releasing the oxygen into the Martian atmosphere.

Since the Mars 2020 Perseverance Rover‘s MOXIE instrument is located inside of the rover’s body and you cannot really it from the outside unless you open it up, we may or may not replicate it. If we do make a MOXIE replica for our 1:2 Perseverance replica in the future, we will replicate the appearance structure, but not the functions, so you won’t need to worry about it getting too hot like the real Mars 2020 Perseverance Rover.

Designing the Spokes of the Wheels of the Perseverance Mars Rover Replica

As I mentioned in my previous diaries, the spokes are a challenge in the design and building of the 1:3 Perseverance Mars rover replica.

spokes design Perseverance Mars rover wheel buymarsrovers
The spoke design of Perseverance Mars rover replica’s wheel.

The wheels of the Mars 2020 Perseverance Rover are connected to their axes via bent spokes. In each wheel, there are six spokes.

These twisted spokes were bent twice in two directions from the wheel axis to the inner surface of the wheel. These specially designed spokes serve as a mechanical spring system contributing to buffer bumps during the Perseverance rover’s journey on Mars, while at the same time, they together bear the weight of the entire Perseverance Mars rover.

The spokes of the Mars 2020 Perseverance rover are made of titanium but we will use aluminum or steel to build them in our 1:3 Perseverance Mars rover replica. To ensure that the two bendings of each spoke in the 1:3 Perseverance Mars rover replica mold accurately as the design, we designed a special tool for the bending operation.

Since we will build the 1:4 Perseverance Mars rover static replica first, we will test our spoke design in the 1:4 replica first.

Drills of the Mars 2020 Perseverance Rover

There are 3 types of drill bits that the Mars 2020 Perseverance Rover‘s bit carousal carries. The first type is the coring bit, the second type is the regolith bit and the third type is the abrading drill bit – or the abrader. The three types of drill bits are interchangeable depending on what the target samples are or the purpose of the specific operation. There are 6 coring bits,1 regolith bit, and 2 abraders in the Mars 2020 Perseverance Rover‘s bit carousal. In addition, there is one more launch abrading bit which is located in the Corer on the end of the turret assembly.

The Mars 2020 Perseverance Rover‘s drills are designed to have a rotary percussive motion as an efficient way to extract scientifically selected rock and soil samples from the Martian surface. Our 1:2 Perseverance Mars Rover Replica‘s drills will simulate the rotary percussive motion, but the drills cannot actually drill and collect rock samples like the real Mars 2020 Perseverance Rover‘s drills.

The Mars 2020 Perseverance Rover‘s coring drill bit has a height of 228 mm or 8.98 inches, and the diameter of each of the Mars 2020 Perseverance Rover‘s drills is 1 inch or 27mm. The drill bit’s body material is custom 465 stainless steel coated with titanium nitride. The coring bits collect coring samples – cylindrical-shaped rock samples and will preserve the stratigraphy layers as they are so that in the future if the samples are returned to Earth, scientists can study the stratigraphy of the collected Martian rocks. For our Mars Rover Replica, the coring drill bits will have a height of 114mm, and a diameter of 0.5 inches. The material for our Mars Rover Replica‘s coring drill bit will also be stainless steel but we might not replicate the titanium nitride coating.

Each sample core the Mars 2020 Perseverance Rover collects has a length of 60mm or 2.4 inches, the sample core’s diameter is 0.5 inches or 13mm, and the Martian sample itself is around 10 to 15 grams every tube. For our 1:2 Perseverance Mars Rover Replica, the sample tubes will be empty, and you can put some rocks or sands in them for decoration.

Unlike the Mars 2020 Perseverance Rover‘s coring drill bits, the Mars 2020 Perseverance Rover‘s regolith drill bits, with a height of 185.2mm, or 7.29 inches, collect regolith, which means broken rock materials and dust, but the sealing, transferring, and storing processes are the same as the coring drill bits. For our Mars Rover Replica, the regolith drill bits will have a height of 92.6 mm or 3.645 inches.

Different from both the Mars 2020 Perseverance Rover‘s coring drill bits and regolith drill bits, the Mars 2020 Perseverance Rover‘s abrading drill bits don’t collect any samples. The abrader has a height of 130.7mm or 5.15 inches and its job is to abrade or scrape off the top layer of the rocks in order to expose the surface feature that is not exposed to weathering. Then the science instruments will study the exposed rocks and soils for scientific purposes. The two abraders are planned for 74 missions, and they have an optimized pattern design for the teeth so that when scaping the top layer off of the rocks, the exposed surface will be smooth, which is more convenient for the later analysis. Our Perseverance Mars Rover Replica‘s abrading drill bits will perfectly replicate the appearance structure of the Mars 2020 Perseverance Rover‘s abrading drill bits and our Perseverance Mars Rover Replica‘s abrading drill bits have a height of 65.35 mm, or 2.575 inches.

The Mars 2020 Perseverance Rover‘s launch abrading bit has a height of 108.1mm, or 4.26 inches. The launch abrading bit is pre-installed into the Corer chuck at the center of the end of the turret. It provides a sealing cover for the Corer chuck, and additional abrading power if needed. Our Perseverance Mars Rover Replica‘s launch abrading bit will perfectly replicate the appearance structure of the Mars 2020 Perseverance Rover‘s launch abrading bit and our Perseverance Mars Rover Replica‘s launch abrading bit will have a height of 54.05 mm, or 2.13 inches.

Structurally, the Mars 2020 Perseverance Rover‘s three types of bits have mostly the same features such as the percussion interface and bit sleeve. The coring bits and regolith bits will drill into the Martian surface and collect samples, so they have a sample tube interface for exchanging tubes. However, the Mars 2020 Perseverance Rover‘s abraders don’t have the sample tube interface since they don’t collect actual samples. For the same reason, the coring bit and regolith bit can house a sample tube inside but the abrading bits don’t have this feature. Our 1:2 Perseverance Mars Rover Replica will perfectly replicate the drill bits’ appearance structure but they won’t have the actual functions that the real Mars 2020 Perseverance Rover‘s drills do.

Sample Containers of the Mars 2020 Perseverance Rover

There are two types of sample tubes on the Mars 2020 Perseverance Rover. The first type is the sample containers or the sample tubes, and the second type is the witness tubes, which are introduced in more detail in [Witness Tubes of the Mars 2020 Perseverance Rover].

There are a total of 43 sample tubes on the Mars 2020 Perseverance Rover and 5 of them will be used as witness tubes so eventually, there will be 38 sample tubes with actual samples inside. These tubes will collect, seal and store samples of Martian rock cores, and regolith (broken rocks and dust). Each Mars 2020 Perseverance Rover‘s tube will contain a sample that is carefully and scientifically selected under different and diverse environmental conditions so that it can represent as much geologic diversity as possible of the Martian field site for future analysis. For our 1:2 Perseverance Mars Rover Replica, we will perfectly replicate the appearance and the number of the sample tubes.

The Mars 2020 Perseverance Rover’s sample tubes are made of titanium. There are different coatings on the outer and internal surfaces of the sample tubes. Most of the outer coating is alumina and appears in the color white, but the top and bottom outer surfaces and the internal surface have a coating of nitrided, which appears in gold color. The purpose of the coating is for thermal control. Each of the tubes has a length of 142mm, or 5.59 inches without the seal, which will add 2mm, or 0.08 inches to the sample tube. The sample tube has a diameter of 23 mm or 0.9 inches. As for the sample tubes for our 1:2 Perseverance Mars Rover Replica, we might only use one material, but we will paint the same color as the Mars 2020 Perseverance Rover’s sample tubes.

In order to maintain the cleanness of the Mars 2020 Perseverance Rover’s sample tubes, a fluid mechanical particle barrier glove is designed and attached to each of them. About this fluid mechanical particle barrier glove, we will replicate the appearance structure for our Mars Rover Replica but it won’t actually have the function to maintain the cleanness of the Mars 2020 Perseverance Rover Replica’s sample tubes

After a sample is cashed and studied and carefully sealed, the Mars 2020 Perseverance Rover‘s sample tubes will be left on the Martian surface – a surface that is well-identified for the future sample return mission. If the Mars 2020 Perseverance Rover‘s samples are returned to Earth successfully one day, scientists can learn a great deal from them.

MOXIE of the Mars 2020 Perseverance Rover Part 1

Mars’ atmosphere has around 96% carbon dioxide and there is only 0.13% oxygen. Therefore, it is not suitable for humans to breathe. To find out if it is possible for human exploration on Mars, one of the most important things is to figure out how to make oxygen, not only for humans to breathe but also for helping with burning rocket fuel. The Mars 2020 Perseverance rover‘s MOXIE (short for the Mars Oxygen In-Situ Resource Utilization Experiment) is the instrument that will make oxygen from Mars’ atmosphere. It is like an artificial plant, breathing in carbon dioxide and breathing out oxygen (also some byproducts such as carbon monoxide).

The Mars 2020 Perseverance rover‘s MOXIE instrument is located on the inside of the Mars 2020 Perseverance rover‘s right front belly. It has a mass of 17.1 kg, but due to different gravitational forces between Earth and Mars, MOXIE weighs 37.7 lbs on Earth but 14.14 lbs on Mars. The Perseverance Mars Rover’s MOXIE is expected to operate its first mission within 30 sols after it lands on Mars and passes all the health checkups.

The Mars 2020 Perseverance rover‘s MOXIE is inside of the rover’s body, and you cannot see it from the outside, so our 1:2 Perseverance Mars Rover Replica might not replicate it, or we will replicate it after all the other components are completed. If we do replicate the PMars 2020 Perseverance rover‘s MOXIE instrument, our Mars Rover replica‘s MOXIE will not actually make oxygen, but the appearance structure will be replicated.

Interestingly, the Mars 2020 Perseverance rover‘s MOXIE has 2 microphones so we can hear it making oxygen on Earth. The reason for the microphones is because MOXIE runs by a motor. By listening to the motor running, engineers will know MOXIE is working. Even though our 1:2 Perseverance Mars Rover Replica might not replicate the MOXIE instrument, we may add a speaker inside of the Mars Rover Replica‘s body and make the motor running sound effects to simulate the MOXIE’s working sound.

The Mars 2020 Perseverance rover‘s MOXIE instrument only has a size of a car battery but once it is operating. If we replicate it on our Perseverance Mars Rover replica, it will be half the size of the real Mars 2020 Perseverance rover‘s MOXIE. When operating, the Mars 2020 Perseverance rover‘s MOXIE will use up to around 30% of the Mars 2020 Perseverance rover‘s power, and the heat generated will be so hot that the scientists had to insulate it. Otherwise, the instrument on board or even the whole of Mars 2020 Perseverance rover will get damaged. However, how hot it will get or how much voltage will be used are still to be found out during real operations on Mars.

Mars 2020 Perseverance Rover Structure Components Functions Science Instrument of Mars 2020 Perseverance Rover

PIXL of the Mars 2020 Perseverance Rover Part 1

The Mars 2020 Perseverance rover‘s PIXL is short for the Planetary Instrument for X-ray Lithochemistry, and it is located on the Mars 2020 Perseverance rover‘s turret at the end of its robotic arm.

There are 3 main components of the Mars 2020 Perseverance rover‘s PIXL: the sensor assembly, the body unit electronics (BUE), and the PXL calibration target. [PIXL of the Mars 2020 Perseverance Rover Part 2] will go into details about them. The 1:2 Perseverance Mars Rover Replica we are building will also replicate the appearance structure of these three components.

The Mars 2020 Perseverance rover‘s PIXL is a micro-focus X-ray fluorescence spectrometer. It will shoot a 120 µm diameter X-ray beam to the targeted site and induce X-ray fluorescence on the rock surface. Then PIXL will measure the target surface’s chemical structure at a sub-millimeter level to analyze the detailed composition of the rock, and this can be done in just 10 seconds. The Mars 2020 Perseverance rover‘s PIXL exams the rock and soil autonomously without having to check with Earth each time it runs a scan, so it can record a hyperspectral map of thousands of measured points within hours. The elements that the Mars 2020 Perseverance rover‘s PIXL can detect are Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Br, Rb, Sr, Y, Ga, Ge, As, Zr, Rb, Sr, Y, and Zr. With this information, scientists will be able to search for evidence or signs of ancient Martian microbial life. The PIXL instrument for our 1:2 Perseverance Mars Rover Replica will not actually have these functions, but we will proportionally replicate it on our Mars Rover Replica‘s motorized robotic arm.

PIXL is put on the Mars 2020 Perseverance rover for 3 reasons. The first is to analyze the past chemical composition of the Martian terrain, if the planet was habitable, and if the rocks have the potential to store signs of life. The second reason is to find if there was ever life and if there is any potential for other types of lives. The third reason is to determine what samples are worth collecting and potentially returning to Earth.

There are small motors on the Mars 2020 Perseverance rover‘s PIXL, which makes it like a 6-legged robot. With many degrees of freedom, the X-ray beam can move very easily just like a human hand controls a laser pointer. Our Perseverance Mars Rover Replica will perfectly replicate the robotic legs so they will move like and provide the same mobility to the PIXL on our Mars Rover replica just like the real one on the Mars 2020 Perseverance rover.
