The invention provides a charging system for a robot terminal. The charging system comprises a charging apparatus and a charging pile for the robot terminal, wherein the charging apparatus for the robot terminal is arranged in the robot terminal; the charging apparatus for the robot terminal comprises a robot-mounted battery, a connecting apparatus and a power panel; the charging pile is electrically connected with the robot-mounted battery through the connecting apparatus and used for charging the robot-mounted battery through the connecting apparatus; the robot-mounted battery is electrically connected with the power panel through the connecting apparatus and used for transmitting the stored electric energy to the power panel through the connecting apparatus; and the power panel is used for supplying power supply to the robot terminal. According to the charging system, the novel connecting apparatus is adopted for charging and supplying power to the robot terminal; the stability of charging and power supply of the robot-mounted battery in the charging system is ensured, and meanwhile, a relatively large electric contact area between the connecting apparatus and the connection object of the connecting apparatus is realized, so that the charging and power supply efficiency of the robot-mounted battery are relatively high, and the working efficiency of the robot is further improved consequently.
