Abstract
A robotic device including one or more proximity sensing systems coupled to various portions of a robot body. The proximity sensing systems detect a distance of an object about the robot body and the robotic device reacts based on the detected distance. The proximity sensing systems obtain a three-dimensional (3D) profile of the object to determine a category of the object. The distance of the object is detected multiple times in a sequence to determine a movement path of the object.
Claims18
A robotic device, comprising:
- a base;
- a moveable portion coupled to the base;
- a time-of-flight proximity sensing system coupled to at least one of the base or the moveable portion, the time-of-flight proximity sensing system being configured to detect a distance of an object to the time-of-flight proximity sensing system;
- and
- a control system configured to automatically control a reaction of the robotic device based on the detected distance of the object, wherein the control system is configured to automatically:
- receive multiple detected distances of the object in a time sequence;
- determine a movement direction of the object based on the multiple detected distances;
- compare the movement direction of the object with a movement of the moveable portion;
- and
- control the movement of the moveable portion based on a result of the comparing.
