Designed and built at the Delft Biped Laboratory, Stappo was developed as their first walking robot. In 1995, the prototype biped resulted from Richard van der Linde’s thesis project at the master's level.
Armed with two legs, Stappo functions on two magnets. The robot is capable of walking on flat as well as horizontal surfaces. One of the most important features of Stappo is that the robot is completely autonomous. With a weight of around 2.5 kg, Stappo has batteries that contribute around 0.5kg to its total weight. The propulsion of the robot is offered by small solenoids, creating a push-off force that is around 1.2 times the weight of the body. The push-off is just a state-triggering of its frontal stance angle. The frontal rate that is integrated to the frontal angle is measured by a small gyroscope.
The development of the Stappo robot led to further research and development in the field of walking robots. Following the creation of Stappo, many more advanced robots such as Museum Walker, Denise and Flame were built.
