Build high-response robots with the LEGO ® Technic ™ Medium Angular Motor featuring low-profile design, integrated rotation sensor with absolute positioning and 1-degree accuracy. • Ideal for lower-load, fast-response applications • Low-profile design for smaller models where space is limited • Absolute positioning and integrated rotation sensor for true straight-line control • Tacho feedback control for 1° accuracy • Zero-point markings for simple calibration • Simple form factor for quick building and rebuilding The motor is designed to function in as both a motor and sensor. With the integrated advanced Rotation Sensor, the motor can report both speed and position. The motor can also sense direct user input measures if the output is rotated by hand
