Quasivelocities and stabilization of relative equilibria of underactuated nonholonomic systems
Abstract-- This paper is concerned with the theory of quasivelocities and its applications to control. The equations of motion of a mechanical system are derived using the Lagrange

Analysis of undercompensation and overcompensation of friction in 1DOF mechanical systems
This paper investigates the effects of undercompensation and overcompensation of friction in PD controlled 1DOF mechanical systems. The friction force that is acting on the mechan...

Task-induced symmetry and reduction in kinematic systems with application to needle steering
— Lie group symmetry in a mechanical system can lead to a dimensional reduction in its dynamical equations. Typically, the symmetries that one exploits are intrinsic to the mecha...

Dynamically running quadrupeds self-stable region expansion by mechanical design
— Dynamic stability allows running animals to maintain preferred speed during locomotion over rough terrain. It appears that rapid disturbance rejection is an emergent property o...
