Line follower robot project

exapod shared his line-follower robot in the project log forum:

I’m planning of building a robot with a dspic33fj128mc804 and two encoders for implement some dead reckoning algorithms so for learn something on the dspics i build a line-follower, it uses 6 analog sensors that are read with the auto-scan capability of the chip, the pwm is 12 bit and the control loop runs at almost 30 kHz (it only calculates the line position and the do a very simple PD routine that use fixed point math).

Check out the video after the break.
