ZeroErr designs and manufactures the eRob series of highly integrated rotary actuators (all-in-one robotic joint modules) combining a frameless torque motor, harmonic (strain-wave) reducer, dual absolute encoders, servo driver, holding brake and virtual torque sensor in one housing. It also builds the eCoder series of high-precision magnetic absolute encoders. Products target collaborative, surgical, humanoid and industrial robots, with repeatability to +/-7 arcsec and torque up to 1,180 Nm across 70-170 mm modules. These are robot supply-chain components (actuation and sensing), not a complete robot.
