The BioRob arm is a new type of robot arms based on an antagonistic, series elastic actuation concept inspired by the elastic muscle-tendon apparatus. It boasts an excellent payload to dead weight ratio with reaching range and speed, high inherent safety in case of collisions and an energy-saving control, comparable to a human arm.
Conventional robots with payloads of up to five kg and a similar range usually have a dead weight of five or even ten times bigger than the payload. This is due to the massive construction in order to avoid any inaccuracy of the robot. Thanks to the lightweight design the BioRob arm has a deadweight between three and five kg, depending on the model. Due to his lightweight design and the compliant structure the BioRob arm is able to work in the direct surrounding of the human worker. The BioRob arm can be used for cooperative applications to support the human worker in his daily work. In this way everybody, the BioRob arm and the human worker, can do what they are best in. Thanks to relatively low initial costs the BioRob arm has a payback period of about one to two years. pb
