The application discloses a structure of a pneumatic driving continuum
robot with asymmetric stiffness, comprising: a bone joint, a plurality of groups of bone joints are arranged, and the bone joints are sequentially connected in series to form a
robot main body structure; a direction changing
assembly is arranged between adjacent bone joints, the direction changing
assembly comprises two groups of symmetrically arranged pneumatic half
bellows, and the two groups of pneumatic half
bellows are symmetrically arranged between the adjacent bone joints; a penetrating module is arranged, and the plurality of groups of bone joints are connected in series through the penetrating module; a pneumatic module is connected with the pneumatic half
bellows and drives the pneumatic half bellows to deform; wherein, the adjacent bone joints are connected through a
mortise and tenon structure. The application has different motion characteristics in different directions, can adapt to complex and changeable working environments, and improves the environmental adaptability of the
robot. The two groups of symmetrically arranged pneumatic half bellows in the direction changing
assembly combine the asymmetric stiffness characteristics, so that the robot turns more flexibly and accurately, and can complete a complex motion trajectory.
