Detection module, multifunctional module and mobile robot

Abstract

The invention discloses a detection module, a multifunctional module and a mobile robot. The multifunctional module can detect low obstacles in front of the mobile robot and obstacles above such as the bottom of a sofa by arranging line laser sensors on the upper and lower sides of a camera, so that the obstacle avoidance blind area of the mobile robot is greatly reduced, especially the obstacle avoidance blind area in the advancing direction of the mobile robot, and the mobile robot can precisely clean along the wall, along the bottom of a sofa and along other obstacles in a short-distance and non-physical-collision mode. In addition, the multifunctional module is further integrated with a reseating signal collector, and sensors with different functions are arranged on the same circuit board, so that a compact whole is formed, and the size of the module is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent robots, in particular to a detection module, a multifunctional module and a mobile robot. Background technique [0002] Most of the existing robots use TOF (Time of Flight, time of flight) technology or ranging sensors as sensors for obstacle avoidance detection along the edge, and these sensors have a large detection blind spot, and they are difficult to detect along small obstacles and along the bottom of a sofa. When cleaning obstacles, it may not be possible to accurately identify or fail to identify obstacles, resulting in frequent physical collisions between the robot and obstacles, seriously reducing cleaning efficiency and user experience. In addition, the obstacle avoidance detection sensor and the seat return sensor of most existing robots are set separately, which requires a large space for the mobile robot, which hinders the overall design and layout of the mobile robot.

[0002] Most of the existing robots use TOF (Time of Flight, time of flight) technology or ranging sensors as sensors for obstacle avoidance detection along the edge, and these sensors have a large detection blind spot, and they are difficult to detect along small obstacles and along the bottom of a sofa. When cleaning obstacles, there may be cases where the obstacles cannot be accurately identified or cannot be identified, resulting in frequent physical collisions between the robot and the obstacles, seriously reducing cleaning efficiency and user experience

In addition, the obstacle avoidance detection sensor and the seat return sensor of most existing robots are set separately, which needs to occupy a large space of the mobile robot, which brings obstacles to the overall design layout of the mobile robot.
