VISION-BASED SYSTEM FOR NAVIGATING A ROBOT THROUGH AN INDOOR SPACE

摘要

Methods, systems, and devices are provided for navigating a robot along a route. Navigation is accomplished using an image sensor mounted on the robot, which captures an image of a target. The target comprises a plurality of data zones and a plurality of data indicators organized with no more than one data indicator located within one data zone. The target has a target code based on which of the data zones contains the plurality of data indicators. A target distance between the robot and the target is determined, and, if the target distance is below a distance threshold, then an instruction, based on the target code is used to command the robot.

1. A method for navigating a robot along a route, comprising:
a) providing a target comprising a plurality of data zones and a plurality of data indicators organized with no more than one data indicator located within one data zone, the target having a target code based on which of the data zones contains the plurality of data indicators; b) using an image sensor mounted on the robot to capture an image of a target; c) determining a target distance between the robot and the target based upon the image; and d) if the target distance is below a distance threshold, then determining an instruction based on the target code and commanding the robot based on the instruction.
