Mobile robot with autonomous following obstacle avoidance function

Abstract

The invention discloses a mobile robot with an autonomous following obstacle avoidance function. The mobile robot comprises a shell, two driving rear wheels are arranged at the bottom of the shell, the same driving front wheel is arranged at the positions, on the front sides of the two driving rear wheels, of the bottom of the shell, and rotary brushes are arranged on the two sides of the drivingfront wheel. External objects are blocked by a plurality of fan-shaped plates, an arc-shaped elastic sheet is pressed to be bent and deformed to consume impact force of the external objects, once theshell flips over, a liquid storage film is bulged towards the direction far away from an inner barrel under the action of self gravity, meanwhile, the fan-shaped plates can drive the arc-shaped elastic sheet to move out of the outer barrel, the free end of the fan-shaped plate is in contact with the ground at the falling position firstly, the arc-shaped elastic sheet is in contact with the liquidstorage film, the liquid storage film is compressed and deformed, part of impact force is consumed, the arc-shaped elastic sheet crosses over the liquid storage film and enters the outer barrel again,the end of the arc-shaped elastic sheet is in contact with the surface of the shell and is pressed and deformed, impact force is further consumed, and overall safety is protected.

Description

technical field [0001] The invention belongs to the technical field of robots, in particular to a mobile robot with the function of autonomously following and avoiding obstacles. Background technique [0002] A mobile robot is a comprehensive system integrating environmental perception, dynamic decision-making and planning, behavior control and execution. It integrates multi-disciplinary research results in sensor technology, information processing, electronic engineering, computer engineering, automation control engineering, and artificial intelligence. It represents the highest achievement of mechatronics and is one of the most active fields of science and technology development. With the continuous improvement of robot performance, the application range of mobile robots has been greatly expanded. Mobile robots used in the service industry include cleaning robots, security robots, welcome robots and food delivery robots. Because mobile robots can replace people to complet...

AI Technical Summary

Problems solved by technology

[0003] Because the top of the existing mobile robot is hit by an external object during use, it will cause damage to the top, and when it falls, such as reaching the stairs, generally a part of it is suspended in the air first, and the brakes are not enough. When it continues to move, it will deflect and fall as a whole. Due to the large impact force, its surface or internal components will loosen due to inertia. In severe cases, the components will fall off, which may easily cause the internal components The impact is damaged, and during normal movement, the sensor that detects whether there is an obstacle in front of it is installed directly in front of it. When it hits an obstacle that suddenly appears in front of it, it will affect the service life of the sensor. After the work fails, it will affect normal use

[0004] Therefore, it is necessary to invent a mobile robot with the function of autonomously following and avoiding obstacles to solve the above-mentioned problems. It can reduce the damage caused by overturning and falling during the work process, and reduce the problem of work failure caused by the sensor hitting the obstacle.
