A Passive Mobile Robot with Energy Harvesting Capability

Abstract

The invention provides a passively moving robot with energy collecting ability. The passively moving robot with the energy collecting ability mainly comprises a lobe-type elastic shell body, four ways of power generating devices and a double degree-of-freedom swinging type battery compartment, wherein the lobe-type elastic shell body is composed of four same lobe-type inflatable bags, and the four same lobe-type inflatable bags are assembled as a ball shape in the outer part of the robot; the four ways of power generating devices are evenly distributed on a swinging ring of the robot so that mechanical rotating energy in the two directions can be converted into electric current energy simultaneously; and the double degree-of-freedom swinging type battery compartment is installed in the center of the robot, the mass center of gravity of the double degree-of-freedom swinging type battery compartment is located in the lower part of a ball center of the robot, so that the double degree-of-freedom swinging type battery compartment is capable of storing energy collected by the robot and relatively swinging with the robot shell body along the horizontal axis. The passively moving robot with the energy collecting ability has the outstanding characteristics that the passively moving robot with the energy collecting ability can passively move under the effect of external force of environment, and the energy of the external force can be converted into electric energy which can be stored in the battery compartment. The passively moving robot with the energy collecting ability can carry a micro-type detecting sensor to move for a long time in the ocean or polar environment and carry out the data collecting task, and no power resource is required.

Description

technical field [0001] The invention belongs to the field of special robots, and in particular relates to a passive mobile robot with energy collection capability. Background technique [0002] At present, the information collection of marine environment and polar environment has been paid more and more attention by researchers from all over the world. The marine environment and polar environment are rich in mineral resources, biological resources and space resources, etc. However, due to the complexity of the ocean environment and its vast area, the polar environment is covered by ice and snow all the year round, which is not suitable for human normal life and actions. The smooth implementation of environmental information collection tasks by scientific researchers has brought difficulties. In recent years, the application of autonomous robot technology for detection of dangerous environments has attracted more and more attention. However, due to the fact that the marine e...

Problems solved by technology

At present, among the robots that can convert the external energy in the environment into electric energy, the environmental detection robot that collects solar energy to generate electricity is more common, but this kind of robot requires sufficient light energy in the detected environment on the one hand, and requires the robot to have The surface area is large enough to deploy the panels, and the depths of the ocean and the polar regions of the earth are not covered by sunlight for a long time, so the application of robots powered by harvesting solar energy will be limited in this environment

There is also a common energy harvesting device, which is to use piezoelectric ceramics to absorb the energy of mechanical vibration. Using this energy harvesting method requires the robot to carry an additional power generation device, and there must be vibration during the movement, and the robot in the polar environment Or moving in the ocean environment, it is difficult to generate this desired vibration, and this energy harvesting method is not very ideal.
