The Alice is a very small "sugarcube" mobile robot (2x2x2cm) developed at the Autonomous Systems Lab (ASL) at the École Polytechnique Fédérale de LausanneinLausanne, Switzerland between 1998 and 2004. It has been part of the Institute of Robotics and Intelligent Systems (IRIS) at Swiss Federal Institute of Technology in Zürich (ETH Zurich) since 2006.

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
