Carl Monk has blogged about his experience building and using the MeArm from Phenoptix. The MeArm is a kit made from plastic which, when assembled, gives you a robotic arm controlled using servos. Carl has developed a web interface using the Flash framework to control the arm and has also started to experiment using a PS3 controller. All his code is available here and you can read more about his experience on his blog.
You can see Carl’s PS3 controller working with the MeArm in the video embedded below:
