Abstract

The invention discloses a robot joint actuator with a soft feature. The robot joint actuator with the soft feature comprises a harmonic gear motor, an input turntable, a soft part, an output turntable, a crossed roller bearing and an outer shell body. The input turntable is connected with the harmonic gear motor through first bolts, the soft part is located and installed through a fan-shaped boss on the relative end face of the input turntable and the output turntable, the outer shell body is connected with the end face of a motor through second bolts, and a threaded hole is formed in the end face of an output rotating shaft to be used for being connected with a joint output piece. The robot joint actuator with the soft feature has the advantages of being simple and compact in structure and design, easy to process, beneficial for improving an energy storage feature of a robot and capable of improving safety of human-computer interaction.

Description

technical field [0001] The invention belongs to the technical field of service robots and relates to a robot joint driver with compliance characteristics. Background technique [0002] Robot technology involves many disciplines and fields such as machinery, electronics, communications, computers, automation, sensors and bionics, and is a synthesis of advanced technologies in various fields. Traditional robots are mainly used in the field of industrial robots, and their working environment is relatively fixed, and they do not need to work collaboratively with humans. Therefore, the robot used in these occasions is designed to be bulky and rigid. It is a high-bandwidth fast response system to ensure that the robot has high position accuracy and realizes precise tracking of the running trajectory, and can efficiently realize repeatability. Work. [0003] With the continuous development of robot technology, robots have not only existed in traditional industrial fields. In rec...
