Obstacle avoidance aiding method based on teleoperation mobile robot

Abstract

The invention discloses an obstacle avoidance aiding method based on teleoperation mobile robot. The teleoperation mobile robot in the invention enters a work field under long-distance wireless control of an operator, and transmits information of the work field back to a local operating platform via wireless transmission; the mobile robot is provided with ultrasonic and infrared distance-measuring equipment to measure the distance between the robot and the surrounding obstacles; the mobile robot is also provided with a camera for monitoring field situation and transmitting the field picture to the local operating platform. When encountering an obstacle, the mobile robot firstly sets a motion speed according to the distance from the obstacle and alarms the local operating platform; a local operator can analyze the obstacle according to the field picture information and the vehicle-borne sensor information, and decides to take obstacle avoidance measures or compel the robot to break the obstacle. The invention has the advantages of human-robot cooperation and flexible obstacle avoidance, and can be applied for a mobile robot working in on a complex work field to perform automatic local avoidance aid.

Description

technical field [0001] The invention relates to the field of mobile robot technology and complex environment monitoring. Specifically, an assisted obstacle avoidance method based on teleoperation mobile robot is proposed. Background technique [0002] With the development of mobile robot technology, the autonomous obstacle avoidance ability of mobile robots has been widely used as a basic function to protect the safe work of robots. However, mobile robots performing tasks in complex environments often encounter situations surrounded by obstacles. Some obstacles cannot be broken through or climbed over, while others are easy to break through or climb over. The current autonomous obstacle avoidance function of mobile robots cannot distinguish the specific situation of obstacles and can only choose to avoid them all, which largely limits the ability of autonomous obstacle avoidance mobile robots to perform tasks in complex environments. Completely abandoning the autonomous o...

Problems solved by technology

However, mobile robots performing tasks in complex environments often encounter situations surrounded by obstacles

Some obstacles cannot be dashed or climbed over, while others are easy to dash through or climb over

The current autonomous obstacle avoidance function of mobile robots cannot distinguish the specific situation of obstacles and can only choose to avoid them all, which greatly limits the ability of autonomous obstacle avoidance mobile robots to perform tasks in complex environments

Completely abandoning the autonomous obstacle avoidance ability of the mobile robot and adopting manual control will waste the powerful sensing ability of the mobile robot itself, waste the energy of the operator and reduce the work efficiency of the mobile robot
