Robot-based system developed at Carnegie Mellon detects life in Chile's Atacama desert

... well, and something like it ultimately may enable robots to look for life on Mars," said Alan Waggoner, Atacama team member and director of the Molecular Biosensor and Imaging Center at the university's Mellon College of Science. The "Life in the Atacama" 2004 field season ?from August to mid-October ?was...

Bees solve complex colour puzzles

...h is to exploit this understanding to build seeing robots that, like the bee with its mere one million neurons, can learn to find a simple flower in a meadow, which no machine can do at present. Our lab has reconstructed our specially designed bee flight arena - known as the Bee Matrix - in the virtual worl...

Penguins waddle but they don't fall down, UH researchers say

...ch can be used to build smaller computers for such robots that will become increasingly more life-like. "There is not much research on this issue, so we're hopeful about the results," Kurz said. To facilitate his study, Kurz has created a special platform that contains a pressure mat. As penguins walk...

Robot assisted surgery more accurate than conventional surgery

...ge London, who led the research team, said: "These robots are designed to hold the surgeon's hand in the operating theatre, not take over the operation. This study shows they can be an enormous help, preventing surgeons from making mistakes. More importantly, by showing how the increased accuracy makes a di...

Two nerve cells in direct contact

...ence. For example, engineers developing navigating robots and driving assistance systems rely on simple and robust algorithms such as those realized by nature in insects. The mechanisms of optical flow field analysis are supremely suitable for technical implementation. As part of two projects supported by t...

A first glimpse of the influenza replication machine

...o analyse its structure. We developed a way to use robots to screen tens of thousands of experimental conditions and discovered a piece of the influenza polymerase that we could work with. It is a small part of the entire protein, but it provides interesting insights into how the protein works and how mutat...
