Innovative soft robotics technology spawns new products

The robot gripper invented by researchers at the University of Chicago and Cornell University is now available commercially. Empire Robotics, the company founded to commercialize the invention, is taking orders for the limited first release of its product called VERSABALL, scheduled to ship later this month.

“When we first started with the universal jamming gripper we did not think about industrial applications,” said Heinrich Jaeger, the William J. Friedman and Alica Townsend Professor in Physics at the University of Chicago. “But soon there were inquiries from various companies and in those early days we had to tell them that we are in basic research rather than R&D and that therefore we could not really make robotic grippers for sale.” (more…)

Images Capture Split Personality of Dense Suspensions

Stir lots of small particles into water, and the resulting thick mixture appears highly viscous. When this dense suspension slips through a nozzle and forms a droplet, however, its behavior momentarily reveals a decidedly non-viscous side. University of Chicago physicists recorded this surprising behavior in laboratory experiments using high-speed photography, which can capture action taking place in one hundred-thousandths of a second or less.

UChicago graduate student Marc Miskin and Heinrich Jaeger, the William J. Friedman and Alicia Townsend Friedman Professor in Physics, expected that the dense suspensions in their experiments would behave strictly like viscous liquids, which tend to flow less freely than non-viscous liquids. Viscosity certainly does matter as the particle-laden liquid begins to exit the nozzle, but not at the moment where the drop’s thinning neck breaks in two. (more…)
