Hi,
One of my neighbors said I could have her old power wheel chair. The chair atop the base is not so hot looking and the joystick is broken (mechanically, not electronically) ... but the most important thing is the base.
These power chair bases are made tougher than a freight train and make great robot bases just using a couple of car batteries and a 32A SaberTooth motor driver connected to the motors.
IF the base is too much you can remove the geared motors from the steel tubing frame to build a smaller robot, but as is, these are as good if not better than many BattleBots just needing the added weaponry.
email me direct
wpe...@brainless.org if you're interested and as I'm retired, you can come and get it almost any day any time after 9am and before 7pm.
