This project introduces the solar satellite robot , which also uses the solar pulsation charge and discharge control circuit, but it is another brand new movement mode - moving in the gyro-rotation mode, so it is also called the solar gyro robot.
If you know the friends of BEAM robots, you may already be familiar with the robots of this shape - the two legs in the tripod, plus the bottom turntable connected to the motor, a total of three points to support the ground, the sun will charge the electricity, the motor drive turntable Rotate and then move the robot.

From the above illustration we can see two different shapes, but the principle is basically the same, but there is a little difference in structure (there is a collision ring, which will be explained later).
First, the basic principle
The robot of this project is shaped like an artificial satellite. It is powered by a solar battery. The motor drives the turntable at the bottom to drive the entire robot. Since the movement in the manner of its own rotation is like a rotating gyro, the robot of this project can be called a "gyro robot".
1, the driving principle
The driving principle of this project is also relatively simple, mainly because the motor drives the bottom turntable rotation - the robot has a three-legged bracket, and only one adjacent foot supports the ground, plus the turntable connected to the bottom of the motor, "two feet + Turntable" - three points to support the ground. When the motor drives the turntable to rotate, one of the points rotates, and the other two points support, and the robot can move as a whole.
2, mechanical structure
The robot of this project has a three-legged foot, which mainly has three kinds of structures, and can be adjusted slightly to have different running effects.
1. If the tripod bracket is relatively high (relative to the turntable) and the bottom is smaller with a smaller diameter turntable, the three-point balance is relatively stable. After each charge cycle, the motor can only rotate the turntable a little distance, generally only It can be exchanged by a group of adjacent feet to support the ground with the next set of adjacent feet, and the distance moved per cycle is relatively small.
2. If the tripod is too high (relative to the turntable), the three-point balance is quite stable. Although it can drive the robot to move, because the bracket is too high, it is impossible to exchange the feet supporting the ground, that is, it always starts to move. By default, the feet supporting the ground touch the ground.
3. If the tripod is relatively low (relative to the turntable) and the turntable with a relatively large diameter at the bottom, the three-point balance is relatively unstable, and the operation after each charging cycle can be close to smooth movement, that is, per cycle. The distance moved is relatively larger.
As an extended structural function, the robot of this project can also add a “collision ringâ€: cut a thin strip with PVC to make a ring, and then fix it around the circle with three thin strip brackets. After adding the "collision ring" to the robot, if there is an obstacle in the process of turning and moving, there will be a rebound steering effect, and then continue to rotate (see: version upgrade).
