Project Description
A simple controller program to operate the USB Robot Arm supplied by OWI / Maplin on Mac OS X. Developed in XCode against the IOKit framework.

This small project is the result of a couple of hours work trying to get the OWI/Maplin USB Robot Arm Kit working on the Mac. The kit comes with a PC control program but I can't be bothered switching in and out of boot camp whenever I want to play ;)

The program is by no means complete and is a bit 'rough-and-ready' but I've put it on CodePlex in case it's useful to anyone - maybe as a quick start.

Finally thanks to the ever inspirational Matt Jarvis whose FaceBook photos of his robot arm persuaded me to impulse buy mine and who egged me on to produce this project.
