GoKawiilHobbyKing brushless motors tested for use in small legged robots
An engineer with experience building low-cost running robots at a biomimetic robotics lab conducted mechanical teardowns and performance characterizations of several cheap HobbyKing brushless motors, aiming to assess whether they could serve as precise, torque-controlled actuators. The work notes that existing motor controllers—whether expensive industrial servo drives or basic hobby-grade RC controllers—are poorly suited to these motors' low-resistance, high-current characteristics, especially for the demands of dynamic running.
