The cam plate is driven by the eccentric. The cam plate is configured to roll in the rolling ring. Pins of the pin plate are configured to engage holes of the cam plate, so that the pin plate is driven by the cam plate. The output shaft is fixedly connected to the pin plate. The output shaft is rotatably mounted in the second bearing. The torque detection mechanism is between the first bearing and the second bearing and configured to detect the torque of the output shaft. | 2021-02-04 |
| 20210031363 | ROTARY DRIVE DEVICE AND A ROBOT ARM OF A ROBOT WHICH IS PROVIDED THEREWITH - A rotary drive device includes a rotary drive which is provided with a braking device and which has an output unit which can be driven into a rotary output movement about a rotation axis. The braking device has two braking bodies with braking structures which lie opposite one another and which by way of an actuation device are drivable into a relative switch-over movement in order to either block the output unit in a rotationally fixed manner or to release it for carrying out an output movement. The switch-over movement is effected in the axis direction of a brake rotation axis, about which the first braking body which is drivingly coupled to the output unit is rotatable. The second braking body is non-rotatably arranged on the drive housing. Furthermore, a robot arm which is provided with such a rotary drive device is suggested. | 2021-02-04 |
| 20210031364 | BACKUP CONTROL BASED CONTINUOUS TRAINING OF ROBOTS - Provided are systems and methods for training a robot.
