Abstract
Methods and systems are described for controlling movement and an applied force at the tip of the continuum robot that includes a plurality of independently controlled segments along its length. An estimated force at the tip of the continuum robot is determined based on measurements of loads and positions of each segment. A reference position command and a force command are received from a user interface. The reference position command indicates a desired movement for the distal end of the continuum robot and the force command indicates a desired force to be applied by the tip of the continuum robot to a tissue surface. The position of the continuum robot is adjusted to cause the tip of the continuum robot to apply the desired force to the tissue surface based on the estimated force at the tip of the continuum robot, the reference position command, and the force command.
