Introduction
PID is an algorithm or method of control, which can be widely applied across numerous robotics applications to control mechanisms. It operates based on Error.
- Extension mechanism:
We could use PID to control how much we want to extend(e.g. 1 ft outward, 2 ft outward)
- Driving:
We could use it make a robot drive to any desired point/location(e.g. 1 meter forward or 3 meters east and 2 meters north).
