Scroll deformation mechanism

The invention discloses a rolling deformation mechanism which comprises a vertex unit A, a vertex unit B, a first branched chain, a second branched chain and a third branched chain. Two ends of the first branched chain are movably connected with the vertex unit A and the vertex unit B respectively through a spider 12, the second branched chain and the third branched chain are movably connected with the vertex unit A and the vertex unit B through the spider 12 by a same manner, and driving motors 11 are mounted in the middle of each branched chain to guarantee symmetry of the mechanism. The degree of freedom of the rolling deformation mechanism is 3, the rolling deformation mechanism has high flexibility and deformability, and moving forward and turning can be realized by utilizing deformation of the mechanism, so that the rolling deformation mechanism can adapt to various complex environments.
