Amphibious exoskeleton robot system for rescue in water

Abstract

The invention provides an amphibious exoskeleton robot system for water rescue in the technical field of flood disaster relief auxiliary robots, and the amphibious exoskeleton robot system comprises a sensing module, a basic module and a rigid lower limb exoskeleton, the sensing module comprises a myoelectricity sensor and an inertial sensor, and the basic module comprises a processing module and a driving module. The rigid lower limb exoskeleton module comprises a waterproof knapsack, an inertial sensor is arranged on the joint skin surface, myoelectricity sensors are arranged on the shanks and the thighs, a driving module and a processing module are arranged in the waterproof knapsack and connected, and the inertial sensor and the myoelectricity sensors receive signals. Signals are fed back to the processing module and the driving module, and the driving module indicates the rigid lower limb exoskeleton to make corresponding actions to provide assistance. The inertial sensor is arranged to achieve motion state distinguishing, the electromyographic sensor is arranged to obtain bioelectricity signals of rescue workers to predict the next action, and the rigid lower limb exoskeleton is controlled to make corresponding actions to complete the best assistance work.

Description

technical field [0001] The invention relates to the technical field of auxiliary robots for flood relief, in particular to an amphibious exoskeleton robot system for water rescue. Background technique [0002] At present, in 2020 alone, there have been 33 large-scale heavy precipitations across the country. In principle, every occurrence of heavy precipitation may lead to flood disasters. In recent years, domestic flood disasters have become more frequent, and the intensity of floods and the range of affected populations have also continued to hit new heights. The safety of life and property of countless people is under huge threat, and in flood rescue, rescuers are the patron saints of those in distress. However, due to the huge impact and resistance of the flood, it is very difficult for rescuers to walk in the water, which will quickly consume a lot of physical strength, resulting in limited search and rescue time, low search and rescue efficiency, and lost the best time ...

AI Technical Summary

Problems solved by technology

At the same time, in recent years, underwater exoskeleton robots have also begun to be continuously studied. They mainly focus on the intention perception of a single stroke, but the underwater environment is complex and changeable. If only one stroke is perceived, it is obviously not in line with actual needs. Rescue In the process of flood rescue, personnel may also face multiple rescue environments of walking in water and swimming underwater at the same time. Therefore, on the basis of using bioelectric technology to accurately identify motion intentions, research on intention perception of various motion postures and amphibious exoskeletons It is of great practical significance for robots to improve the safety and security of rescuers
