New Video of Mantis, the Two Ton Hexapod

Posted 28 Mar 2013 at 22:00 UTC by steve

Mantis is a hexapod robot powered by hydraulics and built by Matt Denton. Mantis weighs 1900 kg and covers about 5 meters when standing still. The powerplant is a 42kw Perkins 2.2 diesel engine. 18 hydraulic actuators move the legs. Computer control is provided by a PC-104 controller running GNU/Linux and HexEngine. The robot is equipped with a suite of sensors that includes 6 force transducers, 6 ankle ball joint angle sensors, a body inclinometer, as well as hydraulic and diesel engine monitoring sensors. From the Mantis website:

"This is definitely the largest hexapod we have built so far", says Micromagic founder and Mantis' chief designer Matt Denton. "This walking machine started as an idea back in 2007, we secured private funding in 2009 to start the project and - after three years of design, build and testing - the robot made a first successful test drive in the summer of 2012 at Bestival UK."

Just reading about Mantis is not sufficient to fully grok the awesomeness of this giant robot. Read on for video of Mantis in action! More photos and info on Mantis can be found the Mantis Facebook page

The Pars Rescue Robot Won't Let You Drown

Posted 27 Mar 2013 at 01:38 UTC by steve

Amin Rigi of the RTS Lab in Tehran, Iran let us know about a new rescue robot they're working on. The robot is named Pars. it's a ship-based quadcopter that responds instantly when alerted to potential drowning victims in the ocean, locating them with FLIR, and dispensing life preservers directly over them. The current prototype carries one life preserver and they are working on a new model to carry three life preserver rings. Future models may dispense up to 15 self-inflating rings. A launching platform for use on ships has been designed but more intriguing is an idea for a stand-alone launching platform. From the website:

A sea platform has also been designed for the robot. This platform used satellite data for its control and it uses solar energy for its energy. It is always in the water and the robots are ready for action. When a marine incident occurs it quickly operates and sends the robots to the event to help.

In both cases, the launching platform also serves as a recharging station, keeping the robots in a continual ready state. This looks like a great project and we look forward to seeing future progress reports on the Pars robots. Read on to see some renderings of the robots in action as well as the designs for the launching platforms.

Humanoid Robots Interviewing Children

Posted 25 Mar 2013 at 23:08 UTC by steve

The KASPAR humanoid robot, developed at the University of Hertfordshire has previously been used in studies of human robot interaction with normal and autistic children. We reported in 2007 on KASPAR being used to teach social skills to autistic children. According to a recently released paper, KASPAR is now being used by researchers interested in finding out if children interviewed by a humandoid robot respond in the same way as to human interviewers. In particular they wanted to find out if children would be more or less willing to disclose information to robots. The results surprised the researchers, who had expected to see some preference in the children for either robots or humans. From the paper:

The results were contrary to our expectations. Rather than having a clear preference, the children behaved very similarly towards either of the interviewers (human/robot). The children used similar amounts of words, keywords and filler words when responding to both the robot and the human interviewer. There was also very little difference in the amount of words the children used relative to the amount of words the interviewer used. These findings illustrate that the children communicated with the robot in a similar way to which they did the human interviewer.

They did find one interesting difference. Their measure of the children's eye gaze reveals they spent much more time looking at the robot's face during interviews than they did with human interviewers. For all the details, read the paper by Luke Jai Wood, Kerstin Dautenhahn, Austen Rainer, Ben Robins, Hagen Lehmann, and Dag Sverre Syrdal, titled Robot-Mediated Interviews - How Effective Is a Humanoid Robot as a Tool for Interviewing Young Children?.

Robotic Ocean Cleanup Arrays

Posted 25 Mar 2013 at 20:35 UTC by steve

Boyan Slat has launched the Ocean Cleanup Foundation to develop safe methods of cleaning the billions of tons of plastic that humans have dumped into the world's oceans, where they are poisoning the food chain. His solution involves arrays of booms that would direct small plastic particles into robotic collection platforms. The arrays would be anchored along the radius of the ocean gyres where the massive plastic garbage patches form. The arrays are powered by ocean currents and the booms allow sea life to safely avoiding being trapped. Even better, researchers estimate the system could collect as much 7.2 billion kg of plastic (around a third of what's out there) in a form that could be profitably recycled. From the projects website:

Is it the perfect solution? No. We will be able to retrieve billions of kilograms of plastic from the oceans, but that still won't be 100% of what's in the world's oceans. We’ll need a combination of extraction from the oceans and prevention on land in order to succeed. One of the problems with preventive work is that there isn’t any imagery of these ‘garbage patches’, because the debris is dispersed over millions of square kilometres. By placing our arrays however, it will accumulate along the booms, making it suddenly possible to actually visualise the oceanic garbage patches. We need to stress the importance of recycling, and reducing our consumption of plastic packaging. Furthermore, by developing systems that will intercept plastic before it reaches the sea, we hope to further reduce the impact of plastic on the oceans.

For more see the Ocean Cleanup Project FAQ, see the Wikipedia article on Marine Debris, and for other robotic solutions for cleaning up the plastic, see Resources relevant to sampling and removal of plastic from oceans. Read on to see Boyan Slat's TEDxDelft talk: How the oceans can clean themselves.

Random Robot Roundup

Posted 18 Mar 2013 at 20:14 UTC by steve

We've got two weeks of random stories to unload from the editor's inbox, so let's get started! The University of Michigan says roboticists have a lot to learn from cockroaches. Researchers at Purdue think they're onto a solution for the dendrite problem that causes lithium-ion batteries to explode, and it could make batteries safer, while allowing higher energy densities and faster charging. While we're celebrating better batteries, it's a good time to mention the Raspberry Pi's first birthday party. They're having a webinar on new accessories to celebrate (they've already had their cake). Also, via the FreeIO.org website, Eben Upton's keynote address at PyCon. Roboticists at CMU have been busy robotically disassembling Oreo cookies. MIT is happy about their team of Shafi Goldwasser and Silvio Micali winning the Turing Award for their work in cryptography and complexity theory. AUVSI has released a new study finding that (surprise!) AUVs are good for the economy and will create 70,000 new jobs over the next three years. A reader asked us to remind you about Tekkotsu, a nice Free Software framework for robotics development and education, check it out. Mario Tremblay wrote a blog post over at the RobotShop claiming that "all sciences lead to robotics". Our friends over at the IEEE Spectrum Automaton blog have an interesting post on brainless bristle-bots exhibiting swarm behavior.
