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