The Twisting Tennis Racket

This paper describes, analyzes, and explains a novel twisting phenomenon which occurs in a triaxial rigid body (such as a tennis racket) when it is rotating about an axis initially near its unstable intermediate principal axis.

Event Triggered Stablization

Event-triggered control is an idea that appears pleasing theoretically, as well as relaxes the need to have periodic signalling - robotics, it would reduce computation and communication loads.

A direct method for Trajectory Optimization of Rigid Bodies Through Contact

A paper about trajectory optimization in hybrid systems. Interesting, as it relaxes would be naively been consider a core constraint of hybrid systems - the order at which vector fields are switched through. While specific for a rigid body, it provides a scablable numerical tool to optimizie over the 'aggregate' dynamics, rather than find optimal solutions in each vector field with a known ordering
