Abstract:
A robot arm includes multiple links and joints connecting the links to one another in an articulated manner, wherein, in cooperation with the joints, the links are designed to carry and move a load in space. The joints can be automatically adjusted by motors of the robot arm to move the links. At least one first link has a first casing and a neighboring second link has a second casing. The casings are designed to transfer respective forces and torques resulting from the weight of the robot arm itself and/or the load to the neighboring link. The first casing and/or the second casing has a deformation element designed to form a buffer body in a joint space between the first and second casings, which is changed due to an adjustment of the associated joint. The buffer body at least substantially or completely fills the changeable joint space.
