Abstract
A continuum robot having at least two independently manipulateable bendable section for advancing the robot through a passage, without contacting fragile elements within the passage, wherein the robot incorporates control algorithms that enable the continuum robot to operate and advance into the passage, as well as the systems and procedures associated with the continuum robot and said functionality.
Claims11
A robotic apparatus comprising:
- a continuum robot including a plurality of bending sections including a distal bending section and a proximal bending section wherein each of the bending sections are bent by at least one wire;
- a driver that drives the wire;
- a controller that controls a driving amount of the wire;
- and
- a base affixed to the continuum robot and capable of moving the continuum robot,
- wherein, when the base moves the continuum robot a displacement value, the distal bending section performs a rotational motion, and an angle (ζt) of the rotational motion is greater than 0 degrees, and
- the controller controls the proximal bending section so as to follow the distal bending section while preventing the proximal bending section from performing a rotational motion of 360 degrees or more, based on a bending state of the distal bending section at a time when the distal bending section finishes the rotational motion.
