This is my Isobot Robot version 1.5. I didn't have intention to hack this robot but the faulty board give me no choice.
So after doing some google I found out the serial protocol. Conecting my BS2 to Isobot here is the result.
Next I am going to try out with Pic as it has more Ram and put IR range sensor.
