Alice mobile robot
The Alice is a very small "sugarcube" mobile robot (2x2x2cm) developed at the ASL at the EPFL in Lausanne, Switzerland between 1998 and 2004.
It was designed with the following goals:
- Design an intelligent mobile robot as cheap and small as possible
- Study collective behavior with a large quantity of robots
- Acquire knowledge in highly integrated intelligent system
- Provide a hardware platform for further research
