Design and control of a gravity-assisted underactuated snake robot with application to aircraft wing assembly
… Instead, they are deployed by modulating gravitational torques. By tilting the base link appropriately, the gravitational torque drives each unactuated link to a desired angular position. With simple, compact locking mechanisms, the arm can change its configuration using the actuated base …

Pattern formation and hydrogen production in suspensions of swimming green algae
… orientate by gyrotaxis, a balance between a gravitational torque due to uneven starch deposits causing cells to be bottom heavy and a viscous torque due to fluid flow gradients, and phototaxis, biased movement towards or away from a light source. In Chapters 2 and 3, a stochastic continuum …

Geometric Mechanics of Active Particles
… In the presence of overdamped forces and torques, inertial forces are negligible and time-evolution become purely kinematical in nature. This dissipative structure precludes the existence of a dynamical Hamiltonian and there is therefore no a priori reason for the existence of a conserved …

Constant Orbital Momentum Equilibrium Trajectories of a Gyrostat-Satellite
This dissertation investigates attitude transition maneuvers of a gyrosat-satellite between relative equilibria. The primary challenge in transitioning between relative equilibria is the proper adjustment of the system angular momentum so that upon completing the transition maneuver the …
