Tiny robots could be the micro-builders of the future

How small can a robot get? According to a team of researchers at Georgia Tech, really, really small. Described in the July 23 issue of the journal Soft Matter, the Georgia Tech team has been running complex computational models of swimming robots on the micron (0.001 mm or about 0.000039 inches) scale. At this microscopic level, water takes on very different properties from those of the human scale, but despite these challenges the team believes that such robots could have fascinating practical applications.Read More

Soft, autonomous Meshworm robot moves like an earthworm

In an effort to create robots with soft, pliable exteriors that would be suited to exploring hard to reach places and traversing bumpy terrain, a team of researchers from MIT, Harvard University and Seoul National University has developed a robotic earthworm called Meshworm. Moving in the same manner as an earthworm, it looks disturbingly like an earthworm as it crawls across the floor. However, unlike an earthworm and despite its soft exterior, it is remarkably tough and can survive hammer blows and even being trodden.Read More

Stompy: 18 foot wide, 6-legged, rideable robot in the works

Project Hexapod is aiming to make the construction of large scale robots cheaper and easier for hobbyists with Stompy - an 18 ft wide, 4,000 pound, 6-legged hydraulic robot that you can ride. The Massachusetts-based team behind the project has already made significant progress with the giant robot and are looking to raise funds to complete the ambitious build before making it "open hardware" by releasing all of the plans, diagrams and the list of materials used in the construction to anyone brave enough to build one of their own.

Hanson Robotics unveils latest version of its Zeno humanoid robot

Back in 2007, we did a report on Zeno, a humanoid robot with a remarkable range of movement and impressive artificial intelligence that was aimed at the children’s toy market. Built by Hanson Robotics, the 17-inch (43 cm) tall robot could stand, make eye contact and had artificial intelligence software with voice recognition to enable it to engage in conversations. Projected retail price was US$300. Five years later, Hanson has released a YouTube video announcing that the latest version of Zeno is going into production, though it’s a bit taller and a lot more expensive.Read More

Engineering students build robot capable of creating theoretically infinite WiFi network

In a little over a decade WiFi has flourished to become something that we take for granted every time we go to a coffee shop. The only problem is that in situations where WiFi would be most useful, such as on the battlefield or in a disaster areas, it’s least likely to be available. That’s the problem being tackled by a team of seven undergraduate students at Northeastern University in Boston, MA. As part of their senior project for the Northeastern’s Capstone design program, the team designed and built a robot that can enter rugged territory and create a theoretically infinite WiFi networks as it goes.

Robotic ray could end up flapping through an ocean near you

Sometime in the future, perhaps sometime soon, the robotic jellyfish, octopi and fish cruising the world’s oceans may have to make way for one other companion – the robotic ray. A team led by University of Virginia engineering professor Hilary Bart-Smith has created such a “creature,” in hopes that its autonomously-operated descendants may someday help us humans explore and study the sea, or possibly perform surveillance for the military.Read More

New algorithms improve efficiency of underwater mine-sweeping robots

In addition to human divers equipped with sonar cameras, the U.S. Navy has also trained dolphins and sea lions to search for bombs on and around vessels. All these methods are expensive and can’t always deliver the best performance in all environments. Robots would seem to be the obvious answer and underwater robots have been the focus of much research and development in recent years. Now researchers at MIT have developed new algorithms to vastly improve the navigation and feature-detecting capabilities of these robots.Read More
