Spherical robot with hybrid power generation function

Abstract

The invention discloses a spherical robot with a hybrid power generation function. The spherical robot comprises an outer spherical shell, connecting heads, hollow power generation pipelines, two fixing pieces, a connecting pipeline and a single-electrode friction power generation device. The two fixing pieces are fixed to the two ends of one diameter of the outer spherical shell correspondingly,six connecting ports are evenly formed in each fixing piece, the included angle between each connecting port and the bottom face of the corresponding fixing piece is 30 degrees, the included angles between every two connecting ports are 60 degrees, the hollow power generation pipelines are connected to form an electromagnetic power generation device through the connecting heads, and the two ends of the electromagnetic power generation device are fixedly connected with the corresponding connecting ports of the two fixing pieces. According to the spherical robot, hybrid power generation is achieved by adopting electromagnetism and friction, high-power balanced power generation can be achieved under any wind direction, and the spherical robot has good environmental adaptation and a long-endurance characteristic, and can be widely applied to detection of unknown environments such as a polar region.

Description

technical field [0001] The invention relates to a spherical robot for compound power generation, which is a spherical robot that can be used in polar environments for long-endurance detection. Background technique [0002] The polar region is rich in oil, gas, iron ore and other resources, so the exploration of the polar region has great strategic significance. Due to the special polar environment, more requirements are put forward for polar scientific research robots. At present, most polar scientific research robots rely on their own batteries or fuel to work, and they cannot achieve long-term and long-distance battery life. Therefore, how to realize the long-range and long-distance detection of the robot in the polar environment is a research problem, and the key lies in the regenerative system of the robot's energy and its movement form. [0003] Among them, as a rolling robot, the spherical robot has the characteristics of good dynamic stability and strong motion cont...

But it is more about the active control driving mode of spherical robots, most of which do not have energy regeneration systems

In 1999, the American Institute of Aeronautics and Astronautics developed an inflatable spherical robot based on the principle of tumbleweeds. It is equipped with solar panels for energy supply. If it is directly applied to polar detection, there are many problems. On the one hand, the intensity of sunlight in polar regions is small. , which is not conducive to the photoelectric conversion of the battery board; moreover, the special structure of the spherical robot is not conducive to the installation of the battery board, and it is easy to be damaged during the scientific research

In 2012, NASA Jet Propulsion Laboratory and Caltech jointly developed a spherical robot Moball capable of collecting capabilities. It achieves energy regeneration through 6 mutually orthogonal power generation pipelines installed inside, but it has fewer pipelines. , the frequency of power generation is too low during exercise, which is not conducive to the processing of subsequent electric energy

[0004] Chinese invention patent ZL201310558991.0 discloses "a polar long-endurance wind-driven spherical robot". The robot acquires and stores energy through the solar film on the surface of the inner spherical shell, but its airbag spherical shell requires high airtightness. Moreover, the photoelectric conversion efficiency of spherical solar thin films is low, and it is impossible to truly realize long-lasting polar detection work.

Chinese invention patent 201610532055.6 discloses "a preferred methane-like structure wind-driven electromagnetic power generation spherical robot". The robot is completely driven by wind to realize free surge and uncontrollable movement. The internal power generation pipeline is arranged according to the methane structure to supply power to the sensor system. , but its power generation frequency is low, it is difficult to provide enough energy
