| Arty is my 2nd line following
bot (Mini was my first). My first time
around, I kept it simple with no MCU. This time I went with a DevBoard-M8 with 6-channel ADC and 3-channel PWM. Having a microcontroller
gave me much finer control of the sensors and motors and it has paid off
in better performance. I drive both the steering servo and the ESC
directly from the M8. As you can see in the video below, this give the
bot great responsiveness and only requires 1 I/O line for steering and 1
for the drivetrain.
Arty competed in Chibot's November
contest, taking first place in the Basic
Line following contest.
