Problems solved by technology

[0003] There are currently two strategies for robots to deal with collisions: the first strategy is to make the front part of the robot movable. When collisions occur in different directions, the movable casing can trigger switch buttons in different directions (photoelectric switches or physical switch), the robot can recognize collisions in different directions; but because the front shell of the robot is made movable, the appearance of the whole robot is not beautiful enough, the structural design is complicated, the cost of developing molds is too high, and it can only recognize Collisions in the left and right directions, and the physical buttons used have a relatively short life span. After a long time of use, the collision detection module is prone to detection failures
The second strategy is that the shell and the

Embodiment Construction

[0019] Such as figure 1 As shown, the robot obstacle detection system provided by this embodiment includes a housing 10, a base 11 control board 12, two action wheels 13, a universal wheel, two driving motors (not shown in the figure), a motor current detection module 14. Five obstacle detection sensors (respectively numbered 161-165 in the figure) and eight collision detection mechanisms (respectively numbered 171-178 in the figure).

[0020] The housing 10 is in the shape of a disc box, and the base 11 is fixedly connected to the bottom of the housing 10 . The control board 12 and the motor current detection module 14 are disposed in the casing 10 . Two action wheels 13 are arranged side by side on the base 11 , two driving motors respectively drive one action wheel, and the control ends of the two driving motors are connected to the action control signal output end of the control board 12 . The detection end of the motor current detection module 14 detects the currents of...

Abstract

The invention discloses a robot obstacle detection system and method. Bumping detection is realized by a capacitance induction principle; simplified design, simplified assembling, lowered die cost and long service lifetime of a robot structure are ensured; in addition, bumping in a plurality of refining directions can be identified, and combined with a motor current detection method, the obstacles in a robot moving space, which cannot be identified by capacitance induction, can be identified by means of analysis.

Description

technical field [0001] The invention relates to the field of intelligent robots, in particular to an obstacle detection system and method applied to intelligent robots. Background technique [0002] With the improvement of living standards, more and more people desire more personal time in order to enjoy life. However, fast-paced work and heavy housework take up a lot of people's personal time. With the development of science and technology, mobile robots can gradually replace human beings to undertake simple and repetitive physical labor. Many of these robots must have the ability to walk autonomously, and the movement space of this type of robot often has various obstacles (walls, furniture, etc.), and the robot will inevitably collide with these obstacles, so the robot must be able to Identify the collision and the specific direction of the collision, so as to guide the robot to the next step of motion planning. [0003] There are currently two strategies for robots to...
