A beer can that is actually a robot in hiding:
CAN you see my robot? - YouTube!
Cleverly disguised as a beer can, this prototype robot transforms upon command. Its brain is an MBED control board and the design incorporates two servos. It is controlled by a Wii remote and gets around by walking on its three legs, or rolls for faster getaways. Unfortunately, there is only limited information about the project’s build details.
