Feetech STS3250 Smart Actuator: Evaluation of Accuracy, Torque and Backlash

Comprehensive empirical evaluation of the Feetech STS3250 serial bus servo motor. Performance testing reveals 2-3% deviation from rated speed, excellent positional repeatability (±0.02 mm), and mechanical backlash within 0.5° specification. Includes detailed analysis of torque output, thermal behavior, and dynamic load response.
