Abstract

The invention discloses an independent gas supply pneumatic system capable of providing pneumatic muscles for working, and relates to a pneumatic system. The invention aims to solve the problem that an existing pneumatic system needs a large-volume cylinder to store high-pressure gas and the pneumatic muscles are inflated and exhausted by pressure proportional valve pressure-regulating equipment, so that the pneumatic system cannot be integrated into a mobile robot by reducing a volume and a mass of the pneumatic system. According to the independent gas supply pneumatic system disclosed by the invention, a high pressure cabin and a low pressure cabin are arranged oppositely and are communicated by a gas pump; a battery is connected to the gas pump and supplies power to the gas pump; the high pressure cabin is connected with an air filtering valve and provides a gas source for a pneumatic execution unit by one switching pneumatic system; the low pressure cabin provides an exhaust space for the pneumatic execution unit by another switching pneumatic system; a high-pressure-cabin pressure sensor is used for measuring an in-cabin pressure of the high pressure cabin; a low-pressure-cabin pressure sensor is used for measuring an in-cabin pressure of the low pressure cabin. The independent gas supply pneumatic system is particularly suitable for a frog swimming simulation robot.

Description

technical field [0001] The invention relates to a pneumatic system that can be integrated on a mobile robot body, in particular to an independent air supply pneumatic system that provides pneumatic muscle work. Background technique [0002] Pneumatic muscles are widely used in robot drives due to their light weight, small size, large output force, and passive compliance. However, pneumatic components generally require large and heavy air sources, processing equipment, and pressure regulating systems. For this reason, it is of great significance to design a pneumatic system that can be integrated in the robot body and has a small size. [0003] Conventional pneumatic systems require large-volume cylinders to store high-pressure gas, and the pneumatic muscles are inflated and exhausted through pressure regulating devices such as pressure proportional valves. However, pressure regulating devices such as pressure proportional valves are large in volume and mass, which is not con...
