I tried one of these airwheels once. If you don't mind me asking, how many times did you break your nose when it flipped?

I would suggest adding some sort of metal bars close to the floor. That way when it flips it doesn't break the robot.

have you tried using two separate arms, one for the front of the wheel and the other for the back? you might be able to achieve a better weight distribution that way.

Hey Sudo,

Only crashed once while looking sideways trying to read my rated speed in a digital sign. Scrached knee only.

Putting a servo arm on the side would make it move forward and backward more efficient but turning would could be more of a challenge. However opposing pendulum motions on each of these ends could make it twist. HHHHmmmm...

I followed Dave's suggestion and powered the servos independently of the EZb per this diagram below:

The servos were much more responsive and browned out less but it still seemd to draw too much current from the 12 v 1A power supply causing the Ezb to reset.

I'm going to scrap this idea for my laundry cart bot for a more practicle 6 wheel machine. It'll be two wheelchair motors in the center with 4 swivel wheels on the corners. I'm using a high tech looking full tower computer case for the base. I'll be posting updates on this thread: synthiam.com/Community/Questions/6788

Thanks so much for all your support.

You guys are awsome! Bill
