Abstract: The present invention discloses an all-round observation under-actuated capsule robot and an axis rolling-over locomotion method thereof by magnetic field control. A radially magnetized NdFeB magnet ring is loaded into an inner cavity of a capsule sphere in a non-connected way, and the NdFeB magnet ring independently idles with the rotating magnetic field around a capsule axis and is completely suspended in the inner cavity filled with silicone oil in the capsule sphere.
