The application relates to mobile robot technology and particularly relates to a multi-loop spherical robot derived from a Bricard mechanism, which is composed of a first spherical shell, a second spherical shell, a third spherical shell, a fourth spherical shell, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a fifth connecting rod, a sixth connecting rod, a seventh connecting rod, an eighth connecting rod, a first connecting base, a second connecting base, a third connecting base, a fourth connecting base, a fifth connecting base and a sixth connecting base, and a driving motor, wherein the multi-loop derived from the Bricard mechanism is combined with the spherical shell, a new configuration of a single-degree-of-freedom driving spherical robot is obtained, and the spherical robot has the motion ability of a tumbling gait, a peristalsis gait and a self-rotation gait.

This utility model discloses an adjustable multifunctional elderly chair, relating to the field of electric reclining chair technology. It includes a fixed frame with a higher front and lower back, a connecting column fixedly connected to the front end of the upper side of the fixed frame, a seat plate rotatably connected to the connecting column above the fixed frame, a back plate rotatably connected to the end of the seat plate away from the connecting column, and a leg plate rotatably connected to the connecting column. Support columns are fixedly connected to both ends of the upper side of the seat plate near the connecting column along the width direction, and elbow plates are hinged to the upper side of the support columns. Connecting blocks are fixedly connected to both ends of the seat plate near the connecting column along the width direction, and the two connecting blocks have round holes adapted to the connecting column, allowing the connecting blocks to fit onto the connecting column and rotatably connect to it. Two electric telescopic cylinders are arranged below the side of the seat plate away from the connecting column. This device improves the comfort of the elderly user.
