Joint Actuator

Designed for High-Performance Robots

A robot joint does more than generate torque—it also serves as a load-bearing structural element and enables a more integrated robotic-arm design.

It is an excellent choice for robotics competitions, DIY projects, research, education, and robotic system development.

Two Cable-Exit Configurations

Choose between side-exit and rear-exit cabling for greater flexibility in mechanical design.
21-Bit Dual Encoders

Provides single-turn absolute position sensing at the output shaft and retains position data after power loss,
allowing the system to restore its state reliably during repeated experiments and demonstrations.
