Every hand is different. The motor must be small, strong, cool-running and long-lasting.
Finger joint spaces are extremely constrained—every millimeter and gram impacts performance.
Insufficient torque forces higher gear ratios, compromising response speed, transparency, and back-drivability.
Unit-to-unit variations increase calibration costs. High-volume manufacturing requires precision consistency and reliable supply chains.
