This is a prebuilt customized programmable triangular omni vectoring robot platform (TP-251-003) that uses Nexus omni wheels. Its a great light duty robot kit great for indoor robotics that can vector in any direction controlled with Arduinos and xBee's.
We have a bunch of power supplies laying around. This is a bag of 5 randomly selected power supplies (wall warts). 110VAC input. About 6 inches of wire with no ends. If you need a power supply (wall wart), you can't beat this deal.
