Abstract: In order to improve intelligence of exploration robot, an electrical system taking ARM architecture as core was designed. The system adopts techniques including 2.4 GHz wireless communication, closed-loop control of motors, control of multi degree of freedom mechanical arm and multi sensor information fusion to achieve functions of obstacle avoidance, obstacle crossing, positioning, communication and sensor measurement. It uses photovoltaic effect and improved hill climbing method to realize maximum power point tracking, and solves energy consumption problem of exploration robot.
