HONPINE TCHL Harmonic Robot Joint Actuator systematically addresses the core pain points in robotics development—limited performance, complex integration, and structural constraints.

The selection of robot joint actuators for humanoid robots is essentially a precise matching of functional requirements, performance trade-offs, and cost control. Among today’s mainstream solutions, harmonic joint actuators are typically prioritized for upper limbs, while planetary joint actuators are favored for lower limbs. This combination is not accidental, but rather the optimal solution derived from the distinct motion characteristics of the upper and lower body. The differentiated approaches taken by companies such as Unitree and UBTECH also stem from specific considerations tied to their product positioning.
