Future surgeons may use robotic nurse, 'gesture recognition'

  • PDF
TechAndComputer (Feb. 3, 2011) — Surgeons of the future might use a system that recognizes hand gestures as commands to control a robotic scrub nurse or tell a computer to display medical images of the patient during an operation.

Both the hand-gesture recognition and robotic nurse innovations might help to reduce the length of surgeries and the potential for infection, said Juan Pablo Wachs, an assistant professor of industrial engineering at...

For robust robots, let them be babies first

  • PDF
TechAndComputer (Jan. 21, 2011) — Want to build a really tough robot? Forget about Terminator. Instead, watch a tadpole turn into a frog.

Or at least that's not too far off from what University of Vermont roboticist Josh Bongard has discovered, as he reports in the January 10 online edition of the Proceedings of the National Academy of Sciences.

In a first-of-its-kind experiment, Bongard created both simulated and actual robots that, like tadpoles...

Robotic ghost knifefish is 'born'

  • PDF
TechAndComputer (Jan. 19, 2011) — Researchers at Northwestern University have created a robotic fish that can move from swimming forward and backward to swimming vertically almost instantaneously by using a sophisticated, ribbon-like fin.

The robot -- created after observing and creating computer simulations of the black ghost knifefish -- could pave the way for nimble robots that could perform underwater recovery operations or long-term...

New cognitive robotics lab tests theories of human thought

  • PDF
TechAndComputer (Dec. 31, 2010) — In a new Cognitive Robotics Lab, students at Rensselaer are exploring how human thought outwits brute force computing in the real world. The lab's 20 programmable robots allow students to test the real-world performance of computer models that mimic human thought.

"The real world has a lot of inconsistency that humans handle almost without noticing -- for example, we walk on uneven terrain, we see in shifting...

A robot with finger-tip sensitivity

  • PDF
TechAndComputer (Dec. 22, 2010) — Two arms, three cameras, finger-tip sensitivity and a variety of facial expressions -- these are the distinguishing features of the pi4-workerbot. Similar in size to a human being, it can be employed at any modern workstation in an industrial manufacturing environment. Its purpose is to help keep European production competitive.

Picture the following: With great care, a robot picks up a gear wheel in one hand, a...
