Taylor Veltrop used a Kinect to read his arm movements which were then carried out by a robot. The robot was programmed using Willow Garage's open-source robot operating system (ROS). As Kit Eaton suggest, this quick experiment provides an illustration of the path towards robotic avatars.

In recent years, ‘social’ robots—cleaning robots, nursing-care robots, robot pets and the like—have started to penetrate into people’s everyday lives. Saerbeck and other robotics researchers are now scrambling to develop more sophisticated robotic capabilities that can reduce the ‘strangeness’ of robot interaction. “When robots come to live in a human space, we need to take care of many more things than for manufacturing robots installed on the factory floor,” says Haizhou Li, head of the Human Language Technology Department at the A*STAR Institute for Infocomm Research. “Everything from design to the cognitive process needs to be considered.”

In the 1970s the CIA had developed a miniature listening device that needed a delivery system, so the agency’s scientists looked at building a bumblebee to carry it. They found, however, that the bumblebee was erratic in flight, so the idea was scrapped. An amateur entymologist on the project then suggested a dragonfly and a prototype was built that became the first flight of an insect-sized machine. A laser beam steered the dragonfly and a watchmaker on the project crafted a miniature oscillating engine so the wings beat, and the fuel bladder carried liquid propellant. Despite such ingenuity, the project team lost control over the dragonfly in even a gentle wind. “You watch them in nature, they’ll catch a breeze and ride with it. We, of course, needed it to fly to a target. So they were never deployed operationally, but this is a one-of-a-kind piece.”

A new form of propulsion that could allow microrobots to explore human bodies has been discovered. The technique would be used to power robots and other devices such as microfluidic pumps from a distance. Finding a propulsion mechanism that works on the microscopic scale is one of the key challenges for developing microrobots. Another is to find a way to supply such a device with energy because there is so little room to carry on-board fuel or batteries. Now a team lead by Orlin Velev at North Carolina State University in Raleigh, US, has found that a simple electronic diode could overcome both these problems. Velev and Vesselin Paunov from the University of Hull, UK, floated a diode in a tank of salt water and zapped the set-up with an alternating electric field.

Robots might one day trace the origin of their consciousness to recent experiments aimed at instilling them with the ability to reflect on their own thinking. Although granting machines self-awareness might seem more like the stuff of science fiction than science, there are solid practical reasons for doing so, explains roboticist Hod Lipson at Cornell University's Computational Synthesis Laboratory.

Google announced at Google IO conference 2011 that they will supply Android@Home framework for home automation to developers, giving them the ability to think of "every appliance in your home" as a potential accessory for your phone. The Google team teased ideas like lights turning on and off based on calendar events, applications talking to washing machines, games automatically adjusting for mood lighting, and basically little green dudes taking care of all the menial duties in your house. One amazing demo was a concept, Android-powered device hub called Tungsten. Using RFID embedded into CD cases the device was able to detect the CD and add it to your library. Another touch and it started automatically.

This is Treebot. As you might expect, Treebot was designed to do one thing: climb trees. It is by no means the first robot able to do this, but its arboreal predecessors (RiSE and Modsnake and accidentally PackBot are just a few) weren't autonomous and didn't have the skills necessary to negotiate the complex network of branches that you tend to find on trees worth climbing.

The Berkeley-based startup is developing exciting new technology that is truly the stuff of comic books and, formerly, of science fiction. Specifically, the company is making wearable, artifi­cially intelligent bionic devices that it calls “exoskeletons”. This has taken shape in two significant forms: eLEGS and HULC. Both of which you can see (as well as an interview with Berkeley Bionics CEO Eythor Bender) in the accompanying video.

This video from PAL Robotics shows the teleoperation system of its REEM robot. Equipped with a Kinect sensor as a motion capture device, a laptop captures the gestures and movements of a person and feeds the result to the robot as commands. This process is called motion retargeting and the teleoperation system was developed by Marcus Liebhardt as part of his master thesis project. PAL Robotics is a small Spanish company based in Barcelona, part of the PAL Group from Abu Dhabi. It develops humanoid robots since 2004 and its latest version of the REEM line of robots focuses towards commercial applications.

IROS 2011 takes place later this month in San Francisco (25th ~ 30th), and as usual there’s so many interesting projects being presented that attendees won’t be able to see them all. We’ve looked at the schedule and will highlight some of them, beginning with this robot developed at the Graduate School of Information Science & Technology, The University of Tokyo, Japan.

Using robots, the two ETH architects, who run the Gramazio & Kohler design studio, have fabricated intricate building parts out of wood, concrete, bricks, and foam, and have used these parts to build complex, beautiful installations in Zurich, London, Barcelona, New York, and other locations.
