With AI capabilities advancing and actuator architectures stabilizing, the demand for robots is accelerating across industries. Yet, while software scales at near-zero marginal cost, hardware does not. Actuator gearboxes remain a stubborn constraint. Every robotic arm however depends on high-torque, low backlash gearboxes for precise, repeatable motion. In this podcast we’ll address the shift from small-batch robotics innovations to true mass deployment, and how the actuation concept itself must be reimagined to enable this shift.

PTFE is widely used as a friction-reducing additive in plastics such as POM, PEEK, and standard polyamides. However, as a PFAS, it faces increasing regulatory restrictions from bodies including ECHA, the US EPA, and Japan’s Ministry of Health, Labour and Welfare. Simply removing PTFE results in increased friction, heat, and wear. The podcast’s solution is to leverage intrinsic material properties rather than additives, enabling compliance without compromising performance.
