A mobile robot with the function of autonomous following and avoiding obstacles

Abstract

The invention discloses a mobile robot with the function of autonomously following and avoiding obstacles, comprising a casing, two driving rear wheels are arranged at the bottom of the casing, and the same driving front wheel is arranged at the bottom of the casing at the front side of the two driving rear wheels , both sides of the driving front wheel are provided with rotating brushes; the invention blocks external objects through a plurality of fan-shaped plates, and the arc-shaped shrapnel is bent and deformed under pressure to consume the impact force of external objects. After the shell is turned over, the liquid storage film Under its own gravity, it becomes convex in the direction away from the inner cylinder. At the same time, the fan-shaped plate will drive the arc-shaped shrapnel to move out of the outer cylinder. The free end of the fan-shaped plate will be the first to contact the ground at the place where it falls. Contact, the liquid storage film is compressed and deformed, which consumes part of the impact force. The arc-shaped shrapnel crosses the liquid storage film and enters the outer cylinder again. Safety.

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.
