Our friend Adam Lassy and his colleagues at MadSci Lab, Havas' Emerging Technologies Lab, have created a really awesome remote presence platform using Spacebrew. The goal for this project was to create a platform that can "remotely control actuators (servos, dc motors, linear actuators, etc) in a flexible way." Spacebrew is used to link the local and remote apps.
Back in grad school I tried to create a remote/internet controllable cat toy like the one featured as an example of how this remote presence platform can be used - my attempts failed miserably. I'm happy that someone has finally been able to pull this off in such an awesome way.
