The Archimedes Drive is a traction-based speed reducer developed to unlock new innovations that require high performance motion technology. Motion transfer occurs through rolling traction interfaces, resulting in zero backlash, inherent overtorque protection, high torsional stiffness, and superior torque density. This allows actuators to combine precision, compactness, and durability without mechanical play or periodic wear patterns.

The Archimedes Drive is suited for humanoid and collaborative robots, robotic arms, and precision automation where minimal backlash and high stiffness are essential. Its compact radial layout reduces inertia and simplifies integration with direct-drive motors or joint modules. The result is repeatable sub-milliradian positioning accuracy and long service life with negligible maintenance requirements.
