Robot overcomes uncertainty to retrieve buried objects

The algorithms behind the system, known as FuseBot, reason about the probable location and orientation of objects under the pile. Then FuseBot finds the most efficient way to remove obstructing objects and extract the target item. But for a robot, this task involves complex reasoning about the pile and objects in it, which presents a steep challenge. With FuseBot, a robotic arm uses an attached video camera and RF antenna to retrieve an untagged target item from a mixed pile. Future iterations of the system could also be used with a mobile robot that searches multiple piles for lost objects.
