Experience Unmatched Precision
Quasi-direct drive technology bridges the gap between high-speed motors and the compliant, torque-dense output demanded by modern robotics. The QDD A2 delivers where others compromise.
High Torque Density
Peak torque far exceeding traditional motor–gearbox assemblies at the same weight.
Backdrivable
Low impedance design enables compliant interaction and safe human contact.
Precise Control
Integrated encoder with < 0.01° resolution for accurate position and force control.
Easy Integration
CAN-bus interface and open SDK let you integrate in hours, not weeks.
