Ant behavior inspires more efficient warehouse robots

When it comes to groups that work together to get a job done, ants have pretty much got the process perfected. That’s why computer scientist Marco Dorigo studied the creatures’ behavior, and created his Ant Colony Optimization model – an algorithmic technique that can be applied to human endeavors, when efficiency is the order of the day. Scientists from Germany’s Fraunhofer Institute for Material Flow and Logistics have now applied these algorithms to a swarm of 50 autonomous shuttle robots working in a parts warehouse, in an effort to create a new and better type of materials-handling system.

Ocean-powered robotic jellyfish could theoretically run forever

Researchers have created a silicone submarinal robot that gets about by mimicking the motion of a jellyfish. The robot is powered by heat-producing reactions catalyzed by its surface, and using hydrogen and oxygen present in the water as fuel. It's claimed that that the Robojelly, so named by its Virginia Tech creators, could run indefinitely, effectively drawing energy from the water in which it swims. Read More

NASA and GM develop power-assisted Robo-Glove

Having trouble getting the lid off that pickle jar? Well, perhaps the Human Grasp Assist device can help. Designed through a collaboration between GM and NASA - and also known as Robo-Glove or K-Glove - the device is based on grasping technology initially developed for the hands of the space-going Robonaut 2. Essentially a power-assisted work glove, Robo-Glove is designed to minimize repetitive stress injuries in both astronauts and autoworkers. Read More

SAFFiR robot could be putting out fires on Navy ships

If there's one thing that you don't want happening on board a ship, it's a fire. People on board burning ships can't simply run out onto the streets, as they hopefully could in the case of a structural fire, plus many people caught belowdecks don't have windows nearby to climb out of. Then, there's also the fact that crew members fighting such fires have to work in narrow, claustrophobic passageways, instead of wide-open roads. Given that fires are particularly possible on military ships, due to attacks by enemy forces, America's Naval Research Laboratory is now developing a special something to help fight fires at sea - it's called SAFFiR, the Shipboard Autonomous Firefighting Robot.

Robot becomes a leader among fish

A couple of years ago, a team of scientists from the University of Leeds succeeded in getting live stickleback fish to follow a computer-controlled “Robofish” as it was moved through their aquarium. Part of the reason for the experiment was to learn about fish behavior, in hopes that human interference in their migration routes could be minimized. While the Robofish was simply a plaster model, researchers from the Polytechnic Institute of New York University recently conducted a similar experiment, but using an actual tail-flapping robotic fish. Their discoveries could help save wild fish populations in the event of environmental disasters. Read More

Quadrotors perform James Bond theme

When we last heard from the University of Pennsylvania's General Robotics, Automation, Sensing and Perception (GRASP) Lab, researchers there had provided video of a swarm of quadrotor robots, which they had programmed to perform some pretty impressive precision flying. Well, now the GRASP quadrotors are back, performing a feat that’s certainly much more ... entertaining. In a video that was presented yesterday at the TED2012 conference in California, a group of the little guys are shown performing the James Bond theme on musical instruments. Read More

Industrial robot to try its hand at sketching portraits

Pity the poor industrial robot. It spends countless hours toiling away at mindless manual labor, never getting a chance to explore its creative side. Well, next month at the CeBIT digital technology trade show, one such robot will get the opportunity. When visitors to the Fraunhofer display take a seat on a provided stool, one of the company's industrial robots will create a pencil sketch of them, then hold up the finished product for everyone to see.

Robotic universal jamming gripper gets “shooting” capabilities

Last year we looked at a universal robotic gripper, which was made by filling an elastic membrane with coffee grounds. The versatile gripper, which is attached to a robotic arm, was able to pick up a wide variety of objects, including a coin or raw egg, which are notoriously difficult for robotic grippers modeled after the human hand to deal with. Now the universal jamming gripper's developers have given it the ability to "shoot" objects some distance, which could enable it to sort objects into different bins, dispose of trash, or maybe even try out for the NBA.
