Humanoid robots are high-dimensional movement systems for which analytical system identification and control methods are insufficient due to unknown nonlinearities in the system s...
This paper deals with global disturbance rejection of nonlinear systems. The disturbance is assumed to be sinusoidal with completely unknown phases, amplitude, and frequencies, bu...
We present Graphite, a system that allows the user to visually construct a query pattern, finds both its exact and approximate matching subgraphs in large attributed graphs, and ...

This report details our development of a computer controlled spotlight with four actuated degrees-of-freedom for pan, tilt, linear movement, and beam focusing. We review the mecha...
An implementation of a biped robot which as capable of dynamic walking by a simple nonlinear control algorithm. is presented. Four D.C. servo motors actuate the knee and ankle joi...
