PIC Lego Robot Controller

Lego Robot Controller:

by Ted Rossin

Library of C routines: CLib.zip
PIC project: LegoBumper.zip (just the source bumper.c )
Schematic: LegoController.jpg
Device: 16F877
- This project controls Lego robots in a way similar to Lego Mindstorms. Two dual H-bridge chips(L283) are used with the PIC microcontroller to control 4 motors. Each motor has speed, direction, float and brake control. Eight A/D inputs are sampled sequentially and the motor PWM control is done in an interrupt routine so that user code can treat the inputs and outputs as continuous values.
  User level control is done in C (compiled with the free HI-TECH PICC Lite compiler). The controller is packaged with 8 Lithium-Ion AA batteries in a brick of legos using no glue or special parts. Programming is done through a RS-232 port using the Serial Port PIC Boot Programmer described above.
  This is really cool stuff.
