8051-based Line Follower Robot
Johnson To - Published on Dec 16, 2010

This is the same robot as my other video but with right angle turning.
Main Parts:
Parallax (futaba) Continuous Rotation Servo
Pololu's QTR-8RC Reflectance Sensor Array
Lab Pro-51 8051 Microcontroller
NiMH 6V Battery (powers servos)
9V Battery (powers sensor and board)
Small plank of Birchwood

Uses two servos for differential driving for power and steering. The sensors refresh at roughly 100 Hz. PWM signals controlling the servos are ~1.5ms pulses spaced 20ms apart. Documentation: Missing
