Hardware design of dust absorption robot based on ARM processor

A household autonomous dust-absorption robot with simple structure and low cost was designed.It cleans a house with semi-automatic or fully automatic function instead of people to a certain extent.The ARM Cortex?-M3 is taken as a core processor.The special motor driver board was designed to realize the closed loop control of walk module through the photoelectric coding feedback circuit.It can detect and avoid the obstacles accurately through the variety of sensor fusion of reasonable layout ultrasonic and infrared sensors.
