By Tolerance Labs engineering team. Specs from the makers’ published data.
13 models: 10–60 N·m peak torque, 7–36:1 gear ratios, 0.24–0.85 kg weight, 50.4 V supply voltage. Every model is below with its key specs and US price.
HighTorque joint modules integrate a brushless motor, reducer, servo driver and encoders, controlled over CAN FD. HTDW and HTPW are planetary, HTPU is an ultra-thin planetary line and HTCP is cycloidal.
