Traction Drive Speed Reducers for Humanoid Robots
Traction Drive Speed Reducers for Humanoid Needs
Archimedes Drive traction drive speed reducers empower Humanoid Robots to move with human-like precision and fluidity. Therefor turning them from mechanical tools into reliable collaborators capable of thriving in complex industrial environments.
Humanoid Robots need overtorque protection to absorbs shocks and incorrect movements.
The backlash-free design of the Archimedes Drive significantly enhances movement accuracy and controls.
High stiffness in the joints increases strength and enables the handling of heavier payloads.
Quiet operation make humanoids more suitable for human interaction.
Its transparency simplifies the control system, requiring fewer algorithm calculations and sensors.

Silent
Rolling contact significantly reduces operation noise levels. This enhances humanoid safety, comfort and discreteness.
Robust
Providing overtorque protection, ensuring that robot joints can withstand shocks and maintain operational integrity.
Transparent
Humanoid Robots need true zero backlash and high stiffness to ensure high transparency.
Built for wheeled humanoids and mobile manipulators
On a wheeled humanoid the arms are the product. Manipulation precision, quiet operation and safe contact with people decide where the robot is welcome, and every gram in a wrist actuator is carried by the elbow, the shoulder and the base.
That is the requirement mix the Archimedes Drive is built for: zero backlash for life (0.2 arcmin max lost motion) for end-effector precision, silent rolling traction contact for human-shared spaces, overtorque protection through micro-slip for everyday collisions, and 75 Nm from 0.8 kg at 65 mm diameter to keep limb inertia low.
Low reflected inertia and backdrivability make force-controlled contact tasks safer around people. No gear teeth means no wear-driven backlash growth over the fleet’s service life.
