Abstract: For the traditional mower pollution, high noise and the need for long artificial operation etc, combined with market demand, develop a small intelligent mowing robot that can make an appointment to work and independent recharge. On hardware, the system is composed of STM32, which consists of a control system, a power system, a sensor system, a communication system and an interactive system; On algorithms and software, Using the self-recharging scheme, the robot can work many times under the reservation mode and reduce the manual operation. In order to solve the robot in slope is incapable of straight line, a slope compensation algorithm is proposed in this paper. To improve the efficiency of robots, an algorithm of self-seeking grass is proposed. System design conforms to the international safety design index, after a long time to test, the machine can work stable and reliable in the reservation mode, self-charging mode and searching grass mode.

Key words: mowing robot, independent recharge, slope compensation, auto searching grass
