Fine Grained Robotics [PDF]

, 1991
Fine grained robotics is the idea of solving problems utilizing multitudes of very simple machines in place of one large complex entity. Organized in the proper way, simple machines and simple behaviors can lead to emergent solutions.

A generalised approach to torsionality maximisation in longitudinal-torsional ultrasonic devices [PDF]

, 2011
A longitudinal-torsional vibration mode has many applications in ultrasonic systems. Obtaining this behaviour could be achieved either by coupling the longitudinal and torsional modes or by degenerating the longitudinal mode, but the results may be ...

Euler buckling in red blood cells: An optically driven biological micromotor

, 2005
We investigate the physics of an optically-driven micromotor of biological origin. A single, live red blood cell, when placed in an optical trap folds into a rod-like shape. If the trapping laser beam is circularly polarized, the folded RBC rotates.
