System description

The humanoid robot RH5 was developed as an assistance robot and against the background of long-term autonomous missions in environments designed for humans, e.g. on a future moon station. A humanoid design of the robot is suitable for interaction with humans as well as for locomotion and manipulation in a real environment. In addition to autonomous and semi-autonomous use, the robot should also be able to be teleoperated by means of an exoskeleton, whereby the visual perception and acting forces and torques of the robot are made available to the controlling person by means of virtual reality methods.

In the mechanical development, a hybrid serial parallel design architecture was employed to achieve a lightweight design with high stiffness and good dynamic properties. In addition to rotatory drive units, linear drive units are also used to exploit non-linear transmission properties.
