Multiple robot control system using grid coordinate system for tracking and completing travel over a mapped region containing obstructions

摘要

A control system for a mobile robot calculates the instantaneous position of the robot, and sequentially stores data representative of the respective robot positions. The system studies and stores a range which the robot is to travel, and calculates a running pattern of the robot in the specific range. The robot is allowed to travel within the range without leaving any region untravelled in spite of the presence of obstructions which alters its path, while checking its own position. Also, the robot compensates for dislocations caused by slippage of its drive wheels or errors in the operation of its motors.
