  • Publication number: 20080078030
    Abstract: Disclosed herein is an intelligent bed robot. The intelligent bed robot includes a pressure sensor-provided mattress, an intelligent robot arm, transfer rails, and at least one gripper. The pressure sensor-provided mattress monitors the position, posture and motion of a user on a bed in real time, and assists the user. The intelligent robot arm includes vertical bars disposed on two opposite sides of the bed and configured to have a predetermined length, a horizontal bar configured to connect the vertical bars to each other, and torque sensors disposed at lower ends of the vertical bar, and measures horizontal and vertical forces applied by the user. The transfer rails guide the intelligent robot arm along a path of movement. The gripper is coupled to the horizontal bar of the intelligent robot arm, and is provided with a finger unit capable of picking up an object.
