Weekly Newswrap

For this week’s newswrap, there are four stories.  First, from Saturday, is the article about the chemical-detecting robot built by a high school student as a science fair project.  Read the article to find out how it was done.  And yes, it was made from LEGOs!  Second, there is a story on a biologically inspired robot. This one is built by the US Navy to clean barnacles from the bottom of ship’s hulls.  The BUG or Bio-inspired Underwater Grooming robot works by using suction to attach to the hull of a ship.  Third is a post on snakebots.  (I couldn’t let the week go by without a snakebot!)  Of course, it is from Carnegie Mellon and the story has great details on the snakebots developed there.  Finally, there are the Tai Chi robots from Beijing.  Watch the video to see the robots in action.

US Navy's Bio-inspired Underwater Grooming Robot

The US Navy is trying to save some money by making their ships more fuel efficient. Keeping a ship's hull free of barnacles, oysters, algae, and other marine life can decrease fuel consumption by up to 40 percent and increase speed by 10 percent. To do the job of cleaning, or "grooming", a vessel's hull, the Office of Naval Research has developed the Bio-inspired Underwater Grooming (BUG) robot (PDF format). The BUG is an autonomous robot that uses negative pressure vortex regenerative fluid movement (which civilians refer to as "suction") to stick to the hull of a ship. Four wheels drive it forward while sensors including biofilm detectors and flourometers allow it to avoid obstacles and plan paths that will take it toward fouled surfaces. The Navy hopes BUGs will be online by 2015, saving up $500 million in maintenance costs per ship while reducing the Navy's carbon footprint. The robot could also be used on non-military ships and yachts. For more info, see the ONR news release.
