Arduino bot third iteration 4
It might seem video is speeded up but it's not.
This time bot was PD program controlled. Turns are softer even with speed.
It's not labeled final because bots were intended to compete at a two event contest: line follower and maze solver. For the latter bot wasn't ready ontime so it didn't compete and even if I don't ever get back to it I consider it a 'work in progress' bot.
