Fascinating robotic projects are shown in this video: Remotely-Controlled Surveillance Rover, Autonomous Self-Transforming Robot, Robotic Hand, and a Robot with an Arm. This is the future of embedded systems and robotics. The Raspberry Pi single board computer was used as the brains for each of the projects.
The following link is the video series explaining step-by-step on how to create a robot. https://www.youtube.com/watch?v=8K7h5xn3fOQ&list=PL_l3mWw4yeavpDs12WGyStGA7M-psj8BJ
