As the second generation of DFRobot's HCR (Home Care Robot) platform, we have equipped it with new motors and wheels, and upgraded some of its sensors. It now has six ultrasonic sensors that give it six directions of surveillance. Our customized high-quality DC motor has high torque with an integrated encoder and quiet performance. It meets the general requirements of a common PID speed controller. The new HCR platform has new expandibility options such as a bracket for installing Microsoft Kinect.
