Meet the Dobot: an arduino-powered 4-axis parallel-mechanism robot arm for designers, makers, educators, and students. It teaches you a thing or two about coding and robots. More importantly, you can program it to perform various tasks. You can use your Dobot to play, complete tasks, and test ideas.
Dobot can be controlled using an app, your PC, gestures, voice, and vision. This is an open source project. More information is available on Kickstarter.
