2. Laser Radar Follow: Laser radar can follow all directions, and can follow any object including people.
3. Depth Camera Follow: Through the camera, you can measure the distance to the front object and follow.
4. Visual Line Inspection: The camera can be navigated by sticking lines. General electrical tape can be used, the color of the line can be blue, black, red, green, yellow, etc.
5. Support APP Control, View Images, Map Creation, and Navigation: Mapping and 2D navigation functions are realized through the ROSAPP of the mobile phone.
6. RRT Autonomous Exploration and Mapping: No need to manually control the car, using the RRT algorithm to autonomously complete the exploration map, save the map, and return to the starting point.
7. Multiple Robotic Car Formations: Multiple robot cars work together, and support distributed formation control and single-point and multi-point navigation
8. Wireless Controller For PS2: Mainboard reserved controller receiver socket for PS2. You can use the remote controller to control the speed and steering, and you can steplessly adjust the speed through the joystick.
