Synovial

Development Kit

Plug & Test: For True Innovators

Experience the Future

The Synovial series is designed to enable human-level actuation for the next generation of Physical AI robots.

Our latest Development Kit includes a fully assembled Synovial, a purpose-designed R&D mount, and an optional output encoder. It lets you evaluate our traction drive technology in your own setup, with dedicated support from IMSystems.

For actuator engineers:
100 Nm output torque across the full tested speed range (20-3000 rpm), from 0.55 kg at 58 mm diameter. Zero backlash and a max lost motion of 0.2 arcmin for the life of the drive. Up to 90% efficiency, and backdrivable. Overload protection through controlled slip. Large centre bore (up to 30% of diameter) and continuous rotation possible. Operational noise below 50 dBA.

* Output torque and efficiency vary with speed and load. 

** Independent dynamometer testing (Oct 2026) of Synovial Development Kit measured 80% efficiency at 1500 rpm and 100 Nm output. Peak efficiency reached 90% at low speed. 

Synovial Development Kit

Includes a Synovial Archimedes Drive, with an optional output encoder.

Specially-designed R&D housing, perfect for exploring the core features of the Archimedes Drive.

Plug & Test: our development kits integrate seamlessly with standard test benches.
