ROBOT CONTROL SYSTEM, ROBOT CONTROL METHOD, AND PROGRAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17982688 titled 'ROBOT CONTROL SYSTEM, ROBOT CONTROL METHOD, AND PROGRAM

Simplified Explanation

The abstract describes a robot control system that controls a mobile robot to autonomously move using a map and range sensor measurements. The system acquires the distance to a nearby object using a range sensor and specifies its position on the map. It estimates the movement vector of the nearby object based on changes in the distance. The system adds a cost to restrict the movement of the mobile robot on the map and updates it based on range sensor measurements. The control system ensures that the mobile robot moves according to the updated cost.

  • The robot control system controls a mobile robot to autonomously move using a map and range sensor measurements.
  • It acquires the distance to a nearby object using a range sensor.
  • The system specifies the position of the nearby object on the map based on the distance from the mobile robot.
  • It estimates the movement vector of the nearby object, indicating its speed and direction, based on changes in the distance.
  • The control system adds a cost to restrict the movement of the mobile robot on the map.
  • The cost is updated based on range sensor measurements.
  • The system performs control to ensure that the mobile robot moves according to the updated cost.

Potential Applications

  • Autonomous navigation and obstacle avoidance for mobile robots.
  • Industrial automation and logistics, where robots need to navigate in complex environments.
  • Service robots in healthcare or hospitality industries, ensuring safe movement around people and objects.

Problems Solved

  • Enables mobile robots to autonomously navigate and avoid obstacles in real-time.
  • Provides a method to estimate the movement of nearby objects based on range sensor measurements.
  • Allows for dynamic updating of movement restrictions based on range sensor measurements.

Benefits

  • Improved safety and efficiency in robot navigation.
  • Real-time adaptation to changes in the environment.
  • Enhanced autonomous capabilities for mobile robots.


Original Abstract Submitted

A robot control system according to an embodiment is configured to control a mobile robot configured to autonomously move by referring to a map, the robot control system being further configured to: acquire a distance to a nearby object measured by using a range sensor; specify a position of the nearby object on the map according to the distance from a position of the mobile robot to the nearby object; estimate a movement vector indicating a moving speed and a moving direction of the nearby object according to a change in the distance to the nearby object; add a cost for restricting a movement of the mobile robot on the map; and perform control so that the mobile robot moves according to the cost updated according to a result of measurement by the range sensor.
