Current Projects [Past Projects]
Architecture for Agile Assembly (AAA)
Reduction of time to market in agile manufacturing
Dynamically-Stable Mobile Robots in Human Environments
We are developing novel dynamically-stable rolling machine and walking machine research platforms to study interactions with people and operating in normal home and workplace environments.
Free-Roaming Planar Motors
We are developing autonomous planar motors for precision positioning.
Psychophysics of Haptic Interaction
Quantitative comparisons of human subjects performing peg-in-hole experiments with real, virtual, and real-remote haptic environments
Robots in Scansorial Environments (RiSE)
We are developing a bioinspired climbing robot with the unique ability to walk on land and climb on vertical surfaces.
Teleoperation with a 12-DOF Coarse-Fine Manipulator
High-fidelity manipulation of remote environments using a 6-DOF robot equipped with a 6-DOF magnetic levitation fine-motion wrist.
Vision-Guided Precision Assembly
Precision automated assembly using coarse-fine positioning.
