Abstract
The invention discloses a flexible-surface spherical mobile robot. The flexible-surface spherical mobile robot comprises an interior rigid ball, a plurality of supporting pipes, a framework, air cavity bottom surfaces and flexible surfaces, wherein the interior rigid ball is connected with each of the air cavity bottom surfaces through each of the supporting pipes, the air cavity bottom surfaces, the framework and the flexible surfaces form a plurality of independent air cavities. The interior rigid ball is located at the center of a sphere, wherein a pneumatic driving source and a control system are placed in the interior rigid ball. The supporting pipes form air channels which are provided with electromagnetic valves, wherein the air channels are connected with an air source and the air cavities. The supporting pipes are hollow and each supporting pipe is connected with each corresponding air cavity. Each electromagnetic valve controls connection and disconnection of each air channel. When the robot needs to move, the air source aerates corresponding air cavities from the interior rigid ball through the electromagnetic valves, and the corresponding flexible surfaces deform under the action of air pressure and interact with an outside environment contacting with the corresponding flexible surfaces so as to produce propelling force. When a motion finishes, the air cavities are exhausted and the flexible surfaces recover original shapes.
