I've just uploaded a few new updates to the dada project website. These are pre-2012 videos but I hadn't got around to editing / uploading them previously.
Dada is a collaborative project I'm working on with Justin Windle of Soulwire fame. The project had to sit on the backburner for awhile but over the last 6 or so months I've been making some good progress in getting our rescued robot arm up and working and writing some control software (the stuff that comes built in to commercial robots).
For those too lazy to follow the link here's one of the videos, showing a home made solution to self calibration and some grid drawing.
