Raffaello D'Andrea on Feedback Control

Posted 27 Feb 2013 at 23:16 UTC by steve

Raffaello D'Andrea gave a really nice talk that introduces the basic concepts of feedback control using live demonstrations from his quad-copter research. The video above is the full talk as given at ZURICH.MINDS. If you want to see his quad-copters do one more cool trick, click through for the latest video of two pole-balancing copters tossing the pole back and forth between each other. The flying robots are great attention-getters but the talk covers some interesting and important topics, so it's worth a listen anyway.

Best Robot Photos of the Week

Posted 26 Feb 2013 at 20:13 UTC by steve

Crunch Time...

Today's edition of best robot photos of the week should be called the good, the bad, and the ugly. Most fall easily into the "good" category including art bots, the Doctor's favorite robot, and a pair of gay Google Androids showing their robot love for each other. But in the "bad" category we've got at least one killer robot, and for "ugly" we offer a creepy female android who wants to hug you. Every week we post a collection of the best robot photos submitted by our readers to our robots.net flickr group. Why? Because everyone likes to see cool new robots! Want to see your robot here? Post it to flickr and add it to the robots.net flickr group. It's easy! If you're not already a flickr member, it's free and easy to sign up. Read on to see the best robot photos of the week!

Random Robot Roundup

Posted 25 Feb 2013 at 20:34 UTC by steve

Kitty Gifford alerted us to an upcoming event in Ithaca, NY on 26 Feb called Science Cabaret that will include a discussion of walking robots. New neuroscience research may have identified some novel network structures that evolved in the human brain. Meanwhile, a study of machine visual recognition suggests that non-metric recognition algorithms may be the best way to go. Garret Fisher of F5 Robotics, let us know about an IndieGoGo campaign to raise money for an ROV that looks like a proprietary version of the very successful open hardware / open software Open ROV project. Our friends at the NooTriX blog let us know about their latest post on questions of robot ethics. The Swirling Brain rounded up stories on the Veter Project, a $10 robot fish pet, and an experiment that torments lab rats using robot rats.

Robots Podcast #124: Insect-inspired navigation

Posted 25 Feb 2013 at 03:45 UTC by John_RobotsPodcast

In this episode Per talks with Michael Mangan from the University of Edinburgh, where he did his PhD in the Insect Robotics Group, with Professor Barbara Webb (previously interviewed by Robots Podcast), about using robotics to study and replicate insect behaviour. His current research focuses on the navigational abilities of desert ants. These ants scavenge for food over long distances despite searing surface temperatures that evaporate pheromone trails too quickly to be useful for guidance. He has recently documented the impressive individual route following behavior of desert ants in southern Spain. This has allowed the first rigorous testing of robotic and biologically plausible models of navigation in the ant world, as viewed by the ant. Mangan is currently constructing these virtual worlds for public use and they will be available from AntNav.org.

A Model-driven Approach to Robot Architecture

Posted 21 Feb 2013 at 19:37 UTC by steve

While you might have trouble getting any two roboticists to agree on what exactly a "robot architecture" is or which one is best, you would probably find agreement that the process of designing a robot architecture is a form of engineering. Piotr Trojanek argues that, if that is the case, then it might be worthwhile to apply the workflow of model-driven engineering development to the task of designing a robot architecture. He lays out his thoughts in a recently published paper called, Model-driven engineering approach to design and implementation of robot control systems (PDF format). From the paper:

"We believe, that model-driven engineering provides the necessary framework that enables the development of methods and tools for robot control and programming in a much more disciplined and efficient manner than before. Dedicated tools for all the steps involved (i.e., definition of domain meta-model, multiple notations, model-to-model and modelto-text transformations) promise that the final solution can be delivered with much less effort."

The paper gives a brief introduction to the predominate 1960s robot architecture known as sense-plan-act (SPA) and its subsequent replacement by the modern subsumption architecture championed by Brooks. The author proceeds to use the Eclipse Modeling Framework to take the reader through the process of using a model-driven approach that ends with a subsumption architecture that is then tested on simulated robots as well as on a real-world LEGO Mindstorms NXT platfrom. The complete architecture modeler and an ADA code generator are available for download from github

Robots.Video: Reboot Robot Robot Reboot

Posted 18 Feb 2013 at 20:11 UTC by steve

It's been a while since we brought you a diversion from all this robot science stuff in the form of a robot music video. How about a look at a strange little song and video by Kim Manning and Andrea Wittgens called, Reboot Robot Robot Reboot. Kim says,

"Writing Reboot Robot was the most fun I’ve had since kindergarten. We locked ourselves away in a room at the Holiday Music Motel with a piano and an iPhone filled with tracks by Matt Willson. We had the intention of writing another serious soulful song and ended up laughing til we cried and writing a song about robots falling in love. We got stuck on this idea that robots reboot themselves when they have sex, it was so ridiculous we knew it just might work."

You may notice a little binary solo in the middle, probably a borrowing from the Flight of the Conchords robot song, The Humans Are Dead. I haven't compared the lyrics to see if it's the same string or not, I'll leave that as an exercise for our readers. For more, you can check out the website, Reboot Robot Robot Reboot.

Training Humans and Robots to Working Together

Posted 16 Feb 2013 at 21:41 UTC by steve

An MIT news release highlights recent research from the Interactive Robot Group at MIT's Computer Science and Artificial Intelligence Lab (CSAIL). The researchers look at the best strategy for ensuring that humans and robots can work side-by-side in manufacturing environments. Not surprisingly, the biggest problem is that people have trouble doing things in the same way each time, which can confuse robots. Various techniques have been tried in the past to solve this problem, most of which involve trying to train the humans. A new approach was needed. From the news release:

So Shah and PhD student Stefanos Nikolaidis began to investigate whether techniques that have been shown to work well in training people could also be applied to mixed teams of humans and robots. One such technique, known as cross-training, sees team members swap roles with each other on given days. “This allows people to form a better idea of how their role affects their partner and how their partner’s role affects them.”

The researchers concluded that the cross-training approach was "an extremely effective team-building tool" when dealing with teams of robots and humans working together. The details of their research can be found in a paper that will be presented soon at the International Conference on Human-Robot Interaction, titled "Human-Robot Cross-Training: Computational Formulation, Modeling and Evaluation of a Human Team Training Strategy" (PDF format).

The Blind See With Robot Eyes, Thanks to NSF

Posted 15 Feb 2013 at 22:38 UTC by steve

A National Science Foundation news release details the long history of NSF funded research that has resulted in the the Argus II Retinal Prosthesis which gained FDA approval yesterday, becoming the first "bionic eye" approved for use in the United States. The cybernetic device consists of video camera glasses that wirelessly transmit an image to a microelectrode neural stimulator array implanted in the damaged retina, providing the brain with an image. The device can restore vision to victims of retinitis pigmentosa. From the news release:

"The implant allows some individuals with RP, who are completely blind, to locate objects, detect movement, improve orientation and mobility skills and discern shapes such as large letters."

The research began in the 1980s and received a first NFS grant in 1994. Twenty years and $40 million later, we have the first cure for this type of blindness. An improved unit that will fit entirely inside the human eye and has 15 times more electrodes exists in prototype form and will someday replace this initial externally worn unit. For more see the Second Sight news release and the functional description of the prosthesis. The NFS also posted several videos detailing the history of the research.
