The pontryagin maximum principle applied to nonholonomic mechanics
— We introduce a method which allows one to recover the nonholonomic equations of motion of certain systems by instead finding a Hamiltonian via Pontryagin’s Maximum Principle...

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...

Full Paper Sheet Control Using Hybrid Automata
Some high speed color printers require that the sheets be accurately controlled in order to achieve a precise alignment of colors. To accomplish this goal a steerable nips mechanis...

Dipole-like fields for stabilization of systems with Pfaffian constraints
This paper introduces a framework that guides the design of stabilizing feedback control laws for systems with Pfaffian constraints. A new class of N-dimensional vector fields, the...

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
