Ada Open Bionics Robotic Hand with PC/Mac Control

Meet the Ada Hand: a fully articulated robotic hand that can be assembled in around 1 hour using simple tools. The hand has 5 degrees of freedom and can be controlled from a PC or Mac using a USB connection. It has a ATMEGA2560 microcontroller, so you can use an Arduino programming environment to program it.

Robotic hands are not always cheap, but this can be yours for £500.
