Abstract:
An apparatus includes an image receiving module configured to collect a depth image provided from a camera, a human body detection module configured to detect a human body from the collected depth image, and an activity recognition module configured to recognize an action of the human body on the basis of a 3-dimensional action volume extracted from the human body and a previously learned action model.
Abstract:
A mobile robot having a returning mechanism includes one or more moving members mounted on a body of the mobile robot; and a cable member connected to one side of the mobile robot so as to supply the mobile robot with electrical power. Further, the mobile robot includes a returning member having a rigidity stronger than the cable member and disposed to wrap the cable member so that the cable member is placed within the returning member; and a take-up unit configured to pull the returning member to keep it taut.
