This kit is composed of a plastic encoder which is fixed on the wheel and a measuring sensor which is fixed on the non-movable axis of the wheel. The plastic encoder rotates at the same speed as the wheel passes in front of the sensor which can precisely measure movement of each wheel (quantity and speed). The kit has a resolution of 36 positions per rotation.
The Position Controller calculates and reports position and average speed data on command. This leaves the main processor free to handle more important tasks like reading GPS coordinates, processing sensor information, and maneuvering complex environments.
The Position Controller is compatible with any microcontroller that uses a single-wire half-duplex asynchronous serial communication (UART) bus. Up to four Position Controller devices can be controlled on the same bus to minimize I/O requirements.
