function description of following car scheme
1
Follow function
The UWB wireless positioning principle is adopted to measure the distance and calculate the angle of the signal sent by the tag, and the corresponding motor movement is controlled according to the distance and angle

The following distance is 20 meters, the positioning angle is 120 degrees, and the nearest following distance is 20cm

2
Anti collision
Four side anti-collision design, the test distance is 0
3m-2m, and the distance can be set

3
Fall prevention
Four side anti fall design, the test distance is 10cm (different parameters can be selected), and it will stop automatically when encountering deep pits or potholes

4
Motion control
Control the movement of the motor: forward, backward, turn, stop and other functions
5
Voice broadcasting and voice control functions
Voice broadcast: greetings, please get out of the way, thank you, etc
Voice control function: voice control startup, shutdown, stop, etc
6
Self check and indication functions
Self checking function
Indicate working status, battery status, etc
