Driving control of the weeding robot
1) Platform driving control algorithm for coordinate path and follow-up
- To set the driving route:
- Learning the driving route by remote driving,
- Tractor and Worker Journey Learning,
- Set coordinates and drive in a straight line
- Follow the path of the orbital autonomous robot through the fusion algorithm of Speed-Planning and Pure-Pursuit
- Utilize the radius of curvature data of the road to control platform speed when entering the turning path
- Stable swivel between two narrow feet (distance approximately 1.4 m)
