Abstract

The invention relates to an energy recovery device and method for a leg shock absorbing mechanism of a field foot-type robot. The energy recovery device comprises a linear generator stator core and a linear generator rotor hollow shaft, and is characterized in that the linear generator rotor hollow shaft is installed in an inner cavity of the linear generator stator core, a winding coil is wound at the inner surface of the linear generator stator core, the outer wall of the linear generator rotor hollow shaft is provided with a hollow cylindrical permanent magnet, and the linear motor rotor hollow shaft is connected with a joint driving and connecting mechanism and an electric energy storage unit. According to the invention, an electromechanical integration design is adopted to reduce the weight of a mobile robot as far as possible while increasing the energy recovery device, electric energy is generated by adopting relative movements of a stator and a rotor in the axial direction according to a mechanism principle of a linear generator, and the mechanism is embedded into a leg of the robot. The kinetic energy in walking can be stored by two springs through elastic potential energy and is then converted into electric energy. Meanwhile, the walking steady performance of the robot can be improved.

Description

technical field [0001] The invention relates to an invention of an energy recovery system, in particular to an energy recovery device and method for a leg shock absorbing mechanism of a footed robot in the field. Background technique [0002] With the development of robot technology, the level of technology from wheeled robots to footed walking robots suitable for field operations is constantly improving, and the environment for exploration and work is also expanding, from standardized environments to field operations. However, because the robots working in the field are far away from the energy supply equipment, the robot's operating endurance is limited and cannot run for a long time, and its demand for energy is also increasing with the increase in the complexity of the robot's operations. For this reason, how to make the robot recover and utilize energy during the operation to reduce its energy consumption, thereby improving its continuous operation ability is one of the...
