Inverse Dynamics-Based Motion Control of a Fluid-Actuated Rolling Robot
2019, Vol. 15, no. 4, pp. 611-622
Abstract
In this paper, the rest-to-rest motion planning problem of a fluid-actuated spherical robot
is studied. The robot is driven by moving a spherical mass within a circular fluid-filled pipe
fixed internally to the spherical shell. A mathematical model of the robot is established and
two inverse dynamics-based feed-forward control methods are proposed. They parameterize the
motion of the outer shell or the internal moving mass as weighted Beta functions. The feasibility
of the proposed feed-forward control schemes is verified under simulations.
