StairBOT is a small robot for indoor environments. On even floor it drives like many other small robots with a differential-drive. In addition it can change its length with a linear guides mechanism with a spindle-drive. By this mechanism it can - together with its omniwheels (with brakes) and a support - reliably climb up and down regular sized stairs. It was one of the objectives for the design to use as few actuators and sensors as possible. Who wants to see the robot climbing up and down two regular sized steps in some short movies, is invited to visit stairBOT's website.
