Abstract: The present invention provides a system and method for operating a mobile robot. Firstly, a mobile robot can be equipped with at least one time-of-flight (ToF) sensor and the mobile robot can travel in an outdoor setting. At least one ToF sensor image related to the outdoor setting can be captured via the at least one ToF sensor. A data processing unit can process the at least one ToF sensor image to identify at least one cluster of pixels on the at least one ToF sensor image based on at least one pixel-clustering parameter. It can be determined whether at least one cluster of pixels corresponds to a hazardous object in the outdoor setting.

Abstract: A collision avoidance method and system for a mobile robot crossing a road. When a mobile robot approaches a road, it senses road conditions via at least one first sensor, and initiates road crossing if the road conditions are deemed suitable for crossing. As it crosses the road, the mobile robot senses, via at least one second sensor, a change in the road conditions indicating the presence of at least one hazardous moving object. In response to determining that at least one hazardous object in present, the mobile robot initiates a collision avoidance maneuver. A mobile robot configured to avoid collisions while crossing a road includes: at least one first sensor configured to sense road conditions, at least one second sensor configured to sense road conditions, and a processing component configured to carry out one or more collision avoidance maneuvers.
