Tech Robots offers several joint module series including RJSII, RJSIIZ, MJX, DJB, etc. RJSII is the second-generation joint module known for its robust performance, high reliability, and excellent heat dissipation. It offers selectable output capabilities ranging from 50 to 1500 N·m, making it suitable for assembling 6-axis collaborative robots. RJSIIZ is the shell-less version of RJSII, providing greater flexibility for customizing appearances and is also suitable for assembling various types of collaborative robots. MJX, the third-generation joint module from Tech Intelligence, features a compact structure and high positioning accuracy, making it suitable for 6-axis and 7-axis collaborative robots, humanoid robots, and more. DJB is the latest joint module designed specifically for humanoid robots and quadruped robots, offering lightweight, compact, and high-torque characteristics.

Tech Robots joint modules come in six models with sizes 14, 17, 20, 25, 32, and 40. These modules can be configured to assemble robots with payload capacities of 3kg, 5kg, 10kg, 15kg, and 20kg. You can refer to the technical specifications of each module to freely combine them into multi-axis robots according to your needs.

Tech Robots provides self-developed joint modules designed for different scenarios and applications. These modules are characterized by lightweight, compact size, high precision, and substantial torque. They exhibit excellent smoothness and reliability, coupled with outstanding cost-effectiveness. They are the ideal choice for assembling collaborative robots, humanoid robots, and quadruped robots.

Tech Robots joint modules integrate independently designed and developed high-performance all-digital servo drives. These drives offer precise control over current, speed, and position, enabling easy implementation of drag-and-teach functionality when combined with a controller.

Tech Robots joint modules have a continuous output torque capacity ranging from 10 to 450 N·m, achieving powerful performance in a compact size. For specific details, you can refer to the technical specifications of each model of joint module.

Tech Robots joint modules support two communication protocols: EtherCAT and CANopen. This makes them compatible with the majority of mainstream control systems available in the market.

Tech Robots joint modules use a dual-encoder full-closed-loop control system, achieving a positioning accuracy of up to 0.001°.

Tech Robots joint modules have a rated speed of 30 RPM, a maximum speed of up to 40 RPM, a maximum rotation speed of 240°/s, and an acceleration of up to 10 RPS/S. The joint modules can rotate freely without hollow through-lines and can achieve ±360° rotation with hollow through-lines.

Tech Robots joint modules use an electromagnetic spring-applied brake, and users can choose the traditional brake according to their needs.

Tech Robots joint modules have a rated operating voltage of 48V, with a minimum power consumption of only 20W under normal joint operation.

The RDM collaborative robot joint servo drive module is a high-performance, DC-powered, and compact all-digital universal servo drive developed based on the most advanced FPGA technology. It has a maximum power of up to 1000W. The module controls the position, speed, and torque of the servo motor through the EtherCAT/CANopen bus, significantly reducing the cost of each node in a multi-axis system.
As an EtherCAT/CANopen slave, the RDM drive module operates with the CoE protocol of DSP-402, supporting position/velocity/torque cycle synchronization, position/velocity/torque curves, PVT, and homing mode.
Through the RS232 or EtherCAT communication interface with PC software, users can program, set, adjust system parameters, upgrade firmware, and save or retrieve configuration parameters.

The DJX series joint module, specifically customized for quadruped robots and bipedal robots, integrates a harmonic reducer, motor, encoder, and driver into one unit. With a lightweight and compact design, it provides greater torque, significantly reducing the assembly difficulty for quadruped and bipedal robots.
