Roach-inspired robots buddy up to climb stairs

If you've ever watched a war or adventure movie, you're well familiar with the "no man left behind" ethic. Now, thanks to an advance involving their VelociRoACH, researchers at University of California at Berkeley's Biomimetic Millisystems Lab have figured out a way to create machines that will have a "no robot left behind" sense of duty – at least when it comes to climbing stairs.Read More

Slithering serpentine robot snakes its way to seabed inspections

It looks like something you'd want to steer clear of in a video game, and most likely real life as well, but this menacing mechanical snake isn't out to hurt anybody. Developed to cut the costs of maintaining underwater equipment, the Eelume robot is designed to be unleashed permanently on seabeds where it will glide through tight spaces tending to gear that is difficult and expensive to reach for us humans.Read More

Bees' supreme obstacle avoidance to make for smarter drones

For more than a century, aeronautical visionaries have turned to the natural world for inspiration and those working with modern-day miniature aircraft that fit in the palm of your hand are no different. By learning how bees safely zip through thick rainforests in spite of their poor vision, scientists say they can endow flying robots with similar capabilities, promising exciting new levels of autonomy for small drones.Read More

Nanopillared surface inspired by insect wings counteracts bacteria

Keeping surfaces bacteria-free is particularly important when it comes to medical devices and implants. In a move that could replace the use of biocidal coatings and antibiotic drugs in such applications, scientists have developed a germ-repelling synthetic polymer inspired by the antibacterial powers of insect wings, which they say could form the basis of resilient new types of eye implants.Read More

Robotic finger mimics human digits as it is heated and cooled

Scientists at Florida Atlantic University have employed a novel thermal training technique to give robotic fingers a natural look and feel. With the ability to curve and straighten as it is heated and cooled, the researchers are hopeful their lifelike new creation will be put to use in underwater robotics and eventually, advanced prosthetic devices.Read More

Drones

Vampire bat-inspired drone can fly and crawl

Robot drones that can both fly and move about on land would vastly improve their usefulness by increasing the areas in which they could operate. Adding wheels of sufficient size to handle most terrains, however, would adversely increase both the weight and size of such a drone. Researchers at the Swiss Federal Institute of Technology in Lausanne (EPFL), building on their earlier developments, have created a drone that uses wings incorporating movable tips, allowing it to both walk and fly.Read More

Robots help create ultra-thin wooden exhibition hall

The Landesgartenschau Exhibition Hall in Stuttgart, Germany, is claimed to be the first building to have its core structure made entirely from interlocking timber sections created by robots. Made up of over 240 individual segments of beech plywood created using a robotic fabrication method, the 17 meter (55 ft) tall, 245 square meter (2,637 sq ft) structure required just 12 cubic meters (424 cubic feet) of timber to construct.

Insect uses gears to enable 200 g hops

Among the mechanical components not found in nature is the spur gear. That is, until now. Zoologists of the University of Cambridge have discovered that the juvenile form of the leaf-hopper Issus coleoptratus has a set of gear-like linkages between the two jumping legs to synchronize the legs during a jump.
