In the context of micromanipulation and microassembly, we propose in this paper a new type of microrobot based on bistable modules : digital microrobots. This concept consists in building a monolithic microrobot using microfabrication technology without anay assembly. It gets over the difficulties of traditional microrobots : non linear control, integration of sensors, noise, etc... Each module contains a bistable structure and actuators. No external energy input is needed to maintain the structure in a stable position. This opens a paradigm in the microrobotics field allowing the design of various kinematics adapted to the microworld.
