Abstract

The present application relates to the field of robot technology, and particularly relates to a bionic intestinal robot, comprising a plurality of first deformation members and a plurality of second deformation members, a plurality of vane valves and a driving member, the first deformation members and the second deformation members are staggered, in use, the driving member has a clockwise rotation state and an anticlockwise rotation state. In the clockwise rotation state, the driving member drives the deformation members to rotate clockwise and forces the inner wall of the through cavity in the first deformation member to contract, and then the driving structure inside the through cavity in the first deformation member is extruded by the contraction of the inner wall, until the driving structure pushes the to-be-conveyed member to the through cavity in the second deformation member. Then the driving member rotates anticlockwise, in the anticlockwise rotation state, the driving member drives the deformation members to rotate anticlockwise and forces the inner wall of the through cavity in the second deformation member to contract, and then the driving structure in the second deformation member is driven to move again, and the bionic intestine which can simulate peristaltic wave is obtained by repeating the above process, and the control is simple, stable and reliable.
