With the encoder motors, the Cutebot Pro provides the flexibility to control the distance the cart travels and enables more precise control of the turning angle. The Cutebot Pro also offers a variety of expansion interfaces to allow for the expansion of additional hardware to stimulate your child's imagination and creativity. Closed-loop motor for more precise driving Compared with Cutebot, our cutebot pro has an upgraded motor. From the open-loop motor to the closed-loop motor, the ELECFREAKS micro:bit Smart Cutebot Pro Robot Car can receive instructions more accurately and the driving route can be more accurate. 4 line-tracking sensors to identify more complex lines ELECFREAKS micro:bit Smart Cutebot Pro is upgraded to 4 line-tracking sensors, which can identify more complex intersections such as crossroads or T-junctions. 4 line-tracking sensor data can be fused into one line of analog data to realize PID line inspection.
