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.

A New Swimming Robot Based on an Amazonian Fish

Anyone who reads RobotNext knows that one of my favorite topics is robots based on nature.  I believe that the field of bionics (or biomimetics) is where many of the next cutting-edge robot designs will originate.  So many current robots have animals as their models.  Many of these have been written about here.  You can find them in the nature section of the archives.  There are snakebots, fishbots, and ratbots, to name a few.  

This particular robot is based on the Amazonian Knifefish.  Dubbed the Gymnobot, this fishbot is designed to propel itself through the water using a fin.  With this robot, the researchers hope to prove the advantages of using a fin instead of a propellor for moving through the water.  Check out this story at the link to Computerworld below.

Snake Robots to Become More Intelligent

If researchers in Norway are successful, a more intelligent snakebot could be crawling its way up a pipe near you.  Scientists at SINTEF in Norway are working to make snake robots as smart as a teenager.  These robotic snakes have many possible applications besides inspecting pipes.  One possibility is that of acting as a robotic fire hose.  The snakebot could use the high pressure water in the hose as its power source and as the fire extinguisher.  Of course, these types of robots are also being explored as possible search and rescue devices since they could reach areas inaccessible to other more conventional machines.  See one of the previous posts here at RobotNext on snakebots.  Read the complete article at PhysOrg.com.  Follow the links below.

Robot Serpent for the Battlefield

Snakebots are back in the news again, but this time as a weapon.  RobotNext has posted articles about robot snakes that have been developed with the purpose of traversing difficult terrain or tight places in order to perform mostly humanitarian or rescue purposes.  This robot will save lives in a different way.  According to the Jerusalem Post, this snakebot is controlled by a soldier with a laptop computer.  In a demonstration of its abilities, it was shown slithering along in caves, tunnels, and buildings as it transmitted video and sound back to the controller.  Check out the article links below for the complete story.
