Abstract
Disclosed is a rigid-flexible coupled continuum robot unit and a continuum robot. In the rigid-flexible coupled continuum robot unit, structural unit blocks are staggered and interconnected to constitute an entire manipulator; two ends of a flexible nickel-titanium rod are respectively connected with two adjacent structural unit blocks; a front-end unit block is arranged at a foremost end of the manipulator; and a rear-end unit block is arranged at a rearmost end of the manipulator. When in use, a memory alloy nickel-titanium rod forms a flexible joint, a limiting clamping jaw and a limiting boss form a rigid joint, the two complement each other, after a drive wire applies pressure, the limiting clamping jaw and the limiting boss are in a wrapping relationship, a motion trail of the robot unit is limited, such that the robot unit always rotates around a center of rotation along an arc.
