Wheels
|
The Mars 2020 rover has six wheels, each with its own individual motor.
The two front and two rear wheels also have individual steering motors. This steering capability allows the vehicle to turn in place, a full 360 degrees. The four-wheel steering also allows the rover to swerve and curve, making arcing turns. |
Solar Panel
| The Mars 2020 rover requires electrical power to operate.
Without power, the rover cannot move, use its science instruments, or communicate with Earth.
Mars 2020 carries a radioisotope power system. This power system produces a dependable flow of electricity using the heat of plutonium's radioactive decay as its "fuel."
The power source is called a "Multi-Mission Radioisotope Thermoelectric Generator" or MMRTG for short. The MMRTG converts heat from the natural radioactive decay of plutonium into electricity. This power system charges the rover's two primary batteries. The heat from the MMRTG is also used to keep the rover's tools and systems at their correct operating temperatures.

Laser
| Mars 2020's 7-foot-long robotic arm can move a lot like yours. It has a shoulder, elbow and wrist "joints" for maximum flexibility. The armlets the rover work as a human geologist would: by holding and using science tools with its "hand" or turret. The rover's own "hand tools" extract cores from rocks, take microscopic images and analyzes the elemental composition and mineral makeup of Martian rocks and soil. |
Camera
| The rover has several cameras focused on engineering and science tasks. Some help us land on Mars, while others serve as our “eyes” on the surface to drive around. We use others to do scientific observations and aid in the collection of samples. There are a total of 23 cameras Engineering cameras 9 Science cameras 7 Entry, descent and landing cameras 7 |
Shovel, rock pick, drill
|
The rover body is called the warm electronics box, or "WEB" for short. As a car body, the rover body is a strong, outer layer that protects the rover's computer and electronics (which are basically the equivalent of the rover's brains and heart). The rover body thus keeps the rover's vital organs protected and temperature-controlled.
The warm electronics box is closed on the top by a piece called the Rover Equipment Deck. The Rover Equipment Deck makes the rover like a convertible car, allowing a place for the rover mast and cameras to sit out in the Martian air, taking pictures with a clear view of the terrain as the rover travels.

2. In groups of 3, you will Design, Draw and Make a Mars Rover out of Lego Technics.
Materials:
Materials:
- Lego Technics
- A4 paper
- Pencil
- Ruler
- Eraser
The drawing and model must have:
- 6 wheels
- 1 camera
- 1 tool at the front that includes a shovel, pick and drill.
- 1 solar panel
- 1 laser that points at the ground
( Take a photo and upload your Mars rover onto your blog.)

Conclusion: Write about what you have learnt.
Mars has 687 days length of the year, the Earth has 364 days in 1 year. I learn that Mars has many days than the Earth. I also learn about body parts of the robot rover there is a lot of camera on the robot rover. I learn about its take too long to take the robot cover to the mars because they really need to plan and think how far the rocket ship will go far away. They really need to make it, if not they waste a lot of money, that's why they really need to think about it and plan it.

Kia ora JV, I can see that you have worked hard to add all of the information so that your blog post is correct, well done.
ReplyDeleteRemember that your conclusion needs to be a summary of the information in your tables. You should write at least 5 several sentences about both of the planets, you must include information from the table.
Than you can write a personal reflection at the bottom of your blog post.
