A truly globetrotter robot

,

A British robotic submarine, Isis, has a very busy schedule these days. Last January, it was taking a 3-week Antarctic dive. In May, it was exploring a giant canyon just off the coast of Portugal. Its next mission will be the exploration of the Whittard Canyon, another deep submarine valley, this time off the coast of Ireland.

This deep-diving remotely operated vehicle (ROV) looks like a van. It is 2.7 meters long, 2 meters high and 1.5 meters wide, it weighs 3,000kg and can dive down to 6,500 meters. But this van has enough equipment to take high-quality videos of sharks appearing at an unusual depth of 3,600 meters…

Carnegie Mellon unveils Internet-controlled robots anyone can build

, , ,

Carnegie Mellon University researchers have developed a new series of robots that are simple enough for almost anyone to build with off-the-shelf parts, but are sophisticated machines that wirelessly connect to the Internet.

The robots can take many forms, from a three-wheeled model with a mounted camera to a flower loaded with infrared sensors. They can be easily customized and their ability to wirelessly link to the Internet allows users to control and monitor their robots’ actions from any Internet-connected computer in the world.

The new tools that make this possible are a single piece of hardware and a set of "recipes" that people follow to build their ’bots. Both are part of the Telepresence Robot Kit (TeRK) developed by Associate Professor of Robotics Illah Nourbakhsh and members of his Community Robotics, Education and Technology Empowerment (CREATE) Lab. Their goal is to make highly capable robots accessible and affordable for college and pre-college students, as well as anyone interested in robots.

Robotic arm gives surgeons microscopic vision, precision

,

Canadian scientists and engineers have developed a robot with a keen sense of touch that will let doctors perform microscopic operations on the brain using the most vivid visuals yet, they said on Tuesday.

A melding of brain surgery and rocket science, the neuroArm allows neurosurgeons to do their riskiest work on patients within a magnetic resonance imaging machine, or MRI, giving a clear 3D picture of even the smallest nerves.

It is expected to be used in its first operation this summer at Calgary's Foothills Hospital, site of the University of Calgary medical school's research facility.

The $24 million robot was created in conjunction with the company that built a robotic arm called CanadArm for NASA space shuttles.

Tiny fingers build micro machines

, ,

Future micro-scale machine parts will need to be made with devices that use tiny, agile ‘fingers’ that can grip, lift and do the assembly work in a controlled, coordinated way.

Engineers at the University of Illinois at Chicago have developed and demonstrated a one-square centimetre device they call the ‘micromanipulator station’ that accomplishes this goal.

‘We think this will be useful in the microfactories of the future,’ said Laxman Saggere, assistant professor of mechanical and industrial engineering, who developed the device with graduate student Sandeep Krishnan.

Introducing the blogbot

, , ,

NEC Corporation has developed a system for automatically creating multimedia blogs by talking to a speech recognition enabled robot which helps illustrate the day’s events.

The system has been developed on NEC's prototype robot PaPeRo, and is initialised when a user begins a conversation with PaPeRo about the events of their day, which the system then records and analyses. PaPeRo then searches for suitable multimedia contents on the internet, including images, illustrations and music, which are automatically uploaded and edited along with the video recording on the user's blog.

A robot for your digital camera?

, ,

According to the Pittsburgh Post-Gazette, researchers from Carnegie Mellon University and NASA Ames will release in March a $200 robot which will transform your digital cameras into powerful image-makers without your help.

Attached to almost any model of digital cameras, the Gigapan robot platform will take continuous snapshots of a place or an event. Then the software provided by the research team will produce a panoramic image built from all these snapshots. And these images will be zoomable. This means you'll have the best of two worlds, big panoramas and startling details.

This GigaPan platform has been developed at Carnegie Mellon University by Illah Nourbakhsh, an associate professor of robotics with the help of the NASA Ames Intelligent Robot Group. This project is part of the Global Connection Project.

Fantastic Voyage: Departure 2009

, ,

An international team of scientists is developing what they say will be the world's first microrobot -- as wide as two human hairs -- that can swim through the arteries and digestive system.

The scientists are designing the 250-micron device to transmit images and deliver microscopic payloads to parts of the body outside the reach of existing catheter technology.
It will also perform minimally invasive microsurgeries, said James Friend of the Micro/Nanophysics Research Laboratory at Australia's Monash University, who leads the team. The researchers hope the device will reduce the risks normally associated with delicate surgical procedures.

While others have tried and failed to create microrobots for arterial travel, Friend believes his team will succeed because they are the first to exploit piezoelectric materials -- crystals that create an electric charge when mechanically stressed -- in their micromotor design.

Human Thoughts Control New Robot

, ,

Scientists have created a way to control a robot with signals from a human brain.
By generating the proper brainwaves—picked up by a cap with electrodes that sense the signals and reflect a person's instructions—scientists can instruct a humanoid robot to move to specific locations and pick up certain objects (see video).

The commands are limited to moving forward, picking up one of two objects and bringing it to one of two locations. The researchers have achieved 94 percent accuracy between the thought commands and the robot's movements.

"This is really a proof-of-concept demonstration," said Rajesh Rao, a researcher from the University of Washington who leads the project. "It suggests that one day we might be able to use semi-autonomous robots for such jobs as helping disabled people or performing routine tasks in a person's home."

R2-D2 Home Entertainment System Rocks

, , ,

There’s only one thing better than a home entertainment system and that’s a home entertainment system that can follow you around the home in the shape of R2-D2.

This is a fully-working robot that stands just under two-feet tall and as CES drags on this is one of the most fun looking gadgets I’ve seen, if for no other reason than R2’s lens is a fully working, LCOS home cinema projector. It can project images up to 80in wide in 800x600 pixel resolution. It has an in-built DVD/CD/MP3 player, FM radio, speakers, outputs for hooking up to surround sound systems, a USB slot, memory card reader and – if that’s not enough – a pop-out iPod dock.

Robot with 'human soul' explores remotely

, ,

Technology that lets a human "inhabit" the body of a distant robot for remote exploration is being tested in Germany.

The robot sits on top of a wheeled platform and has an extendable arm that it uses to manipulate objects. An operator moves the robot around by simply walking or using a foot pedal and can see out of twin cameras positioned on the robot's head after donning a head-mounted display.
The controller's wrist is also connected to a touch sensitive (haptic) interface that controls the robot's arm. Furthermore, a wearable glove provides control over a three-fingered hand at the end of the robot's arm.

Force-feedback gives the operator a sense of the robot's physical interactions with its surroundings – by providing resistance to the user if the robot is pushing up against or grasping something, for example. Meanwhile, microphones relay surrounding noises to a pair of headphones.
