AI Technical Summary
Technical Problem
The brakes of traditional small robot joint modules are difficult to install, have high maintenance costs, and are inconvenient to replace.
Method used
The brake is placed on the front side of the differential braking structure, and the motor is braked through the reducer. The differential braking structure replaces the traditional reducer output structure, which simplifies the disassembly and maintenance of the brake.
Benefits of technology
It simplifies maintenance procedures, reduces maintenance costs, and maintains the robot's original posture in the event of a power outage, preventing it from falling or getting damaged.
