Robotic Glove For Auto Workers And Astronauts
General Motors and NASA are jointly developing a robotic glove that auto workers and astronauts can wear to help do their respective jobs better while potentially reducing the risk of repetitive stress injuries.
The Human Grasp Assist device, known internally in both organizations as the K-glove or Robo-Glove, resulted from NASA and GM's Robonaut 2 – or R2 – project, which launched the first humanoid robot into space in 2011. R2 is a permanent resident of the International Space Station.
When engineers, researchers and scientists from GM and NASA began collaborating on R2 in 2007, one of the design requirements was for the robot to operate tools designed for humans, alongside astronauts in outer space and factory workers on Earth. The team achieved an unprecedented level of hand dexterity on R2 by using leading-edge sensors, actuators and tendons comparable to the nerves, muscles and tendons in a human hand.
Research shows that continuously gripping a tool can cause fatigue in hand muscles within a few minutes, but initial testing of the Robo-Glove indicates the wearer can hold a grip longer and more comfortably.
For example, an astronaut working in a pressurized suit outside the space station or an assembly operator in a factory might need to use 15 to 20 pounds of force to hold a tool during an operation but with the robotic glove they might need to apply only five to 10 pounds of force.
Inspired by the finger actuation system of R2, actuators are embedded into the upper portion of the glove to provide grasping support to human fingers. The pressure sensors, similar to the sensors that give R2 its sense of touch, are incorporated into the fingertips of the glove to detect when the user is grasping a tool. When the user grasps the tool, the synthetic tendons automatically retract, pulling the fingers into a gripping position and holding them there until the sensor is released.
New Medical Technology Saving Lives
Most of the medical advances that we have seen have been with pharmaceuticals, as drug companies compete to introduce new more effective drugs because the patents on many blockbuster drugs are about to expire. But the coolest advances have to do with medical equipment. The age of high-tech medicine is here with even greater advances in development.
Interview - Wireless Assembly Line Robotics - Joseph Citrano III, of Honeywell
A robot has multiple axis, so a wireless switch is sensing position on those different axis. A Limitless™ wireless solution includes wireless switches and I/O devices that are paired and communicate with a PLC or controller interface.
Proximity sensing in robotic clamping applications
Clamping applications often rely on sensors to detect whether the jaws or grippers are in the proper position - open or closed. Though other technologies can be used in place of sensors to determine the open/closed conditions, sensor implementation can increase reliability and obtain data that only a detection device very near the application can provide.
Seegrid Robotic Industrial Trucks - Case Study
The Warehouse Group took to the Robotic Industrial Truck right away when they saw how it helped with their workload. On the manufacturing side, an unexpected secondary benefit is that we removed clutter and unsightly pallets from the work areas so the trucks can maneuver, providing a cleaner, safer work environment.
Instructions For Developing Your Own 3D Camera
The Hackengineer web site has complete plans for building a portable 3d camera. The system uses a Texas Instruments DLP pico projector, Leopard Imaging’s Leopardboard 365 VGA camera board, a small 2x telephoto lens, and a BeagleBoard. The system uses the concept know as Structured-light . Structured light uses a set of temporally encoded patterns that are sequentially projected onto the scene. When the pattern is seen from different viewpoints, the pattern appears geometrically distorted due to the surface shape of the object. This information is used to construct the depth data.
Truss Climbing Robots
Cornell's Creative Machines Lab constructed a robot testbed capable of re-configuring simple truss structures. The robot can add and remove bits and pieces as it goes. The goal of the project is to eventually have similar robots that could be used to assemble structures in difficult situation such as disaster recovery or space exploration.
Julian: A Open Source Grammar Based Speech Recognition Library
Achu Wilson is building a personal robot called Chippu. Using Julian, a special version of Julius Speech Recognition Library , he was able to recognize and execute voice commands. He details the process of getting the library working with ROS in his blog post here.
President Signs FAA Bill To Integrate Unmanned Vehicle Systems By 2015
President Obama has signed the FAA Modernization and Reform Act 2012. The bill will allow the FAA to rebuild its air traffic control system to the next generation technology which will include switching from radar to a GPS air traffic control system. The law will open up the skies to unmanned drones by September 2015.
According to AUVSI (Association for Unmanned Vehicle Systems International), major UAS provisions in the FAA bill include:
Setting a 30 Sept., 2015 deadline for full integration of UAS into the national airspace
Requiring a comprehensive integration plan within nine months
Requiring the FAA to create a five-year UAS roadmap (which should be updated annually)
Requiring small UAS (under 55 pounds) to be allowed to fly within 27 months
Requiring six UAS test sites within six months (similar to the language in the already-passed defense bill)
Requiring small UAS (under 55 pounds) be allowed to fly in the U.S. Arctic, 24 hours a day, beyond line-of-sight, at an altitude of at least 2,000 feet, within one year
Requiring expedited access for public users, such as law enforcement, firefighters, emergency responders
Allowing first responders to fly very small UAS (4.4 pounds or less) within 90 days if they meet certain requirements
Requiring the FAA to study UAS human factors and causes of accidents
Humanoid "Projet Romeo" Greeting Video
Projet Romeo is being developed by Aldebaran Robotic, the same group working on the NAO . Project Romeo is a 4 foot tall humanoid designed to assist elderly and disabled individuals in their daily activities. The robot will be able to walk through a home, fetching food from the kitchen, taking out the garbage, and acting as a loyal companion who helps entertain its owners and keep tabs on their health. The project started in 2009 but the company hasn't released much info about it until now. Below is the first video of Projet Romeo, sitting in a chair, talking and moving his arms and hands:
Origami Robots
Ramses Martinez, Carina Fish, Xin Chen and George Whitesides have published a paper describing a soft pneumatic actuator constructed by combining paper with a silicone elastomer. On pneumatic inflation, these actuators move anisotropically, based on the motions accessible by their composite structures. They are inexpensive, simple to fabricate, light in weight, and easy to actuate. This class of structure is versatile: the same principles of design lead to actuators that respond to pressurization with a wide range of motions (bending, extension, contraction, twisting, and others). Paper, when used to introduce anisotropy into elastomers, can be readily folded into 3D structures following the principles of origami; these folded structures increase the stiffness and anisotropy of the elastomeric actuators, while being light in weight. These soft actuators can manipulate objects with moderate performance; for example, they can lift loads up to 120 times their weight. They can also be combined with other components, for example, electrical components, to increase their functionality.
LS3 AlphaDog Heads Outdoors
Boston Dynamics' LS3 is a four legged military robot designed to go anywhere and carry up to 400 lbs of gear with enough fuel for missions covering 20 miles. The development of LS3 is being funded by DARPA and the US Marine Corps. The project has been in development for sometime and now DARPA released a new video of the prototype traversing hills and uneven ground as they test it outdoors.
Liquid Silver Printed Circuit Boards
University Of Illinois engineers have demonstrated a method of printing liquid silver onto flexible surfaces to create conductive trails. The advantage of silver is that the particles are much smaller than other conventional electronic ink making it easier to print using a inkjet nozzle. Hopefully in the future this silver ink will make printing circuit boards with a simple desktop printer a reality.
Britain's UAV Industry Plans New PR Effort
Companies seeking to enable the routine use of surveillance drones across Britain are planning a long-term public relations effort to counter the negative image of the controversial aircraft. The Unmanned Aerial Vehicle Systems Association (UAVSA), a trade group that represents the drone industry to the UK government, has recommended drones deployed in Britain should be shown to "benefit mankind in general", be decorated with humanitarian-related advertisements, and be painted bright colours to distance them from those used in warzones, details from a UAVSA presentation show.
Plans are also under way to establish corridors of segregated airspace to fly drones – or UAVs – between restricted "danger zones" (airspace where test flights take place) in isolated parts of England and Wales.
A series of presentations given by industry figures in recent months show public opposition is considered a major hurdle. UAVSA has discussed how it could use the media to disseminate favourable stories, creating a narrative that presents the introduction of drones in the UK as part of a "national mission".
Interview - Unmanned Arial Vehicle (UAV) Tech
You can pretty much give UAVs any use you want, provided that you have enough imagination and patience to see that function come alive. Some of the most common uses right now and in the future will probably be related to photography, mapping, surveillance, surveying and any other activities that might involve risking human lives.

ST Robotics Develops the Workspace Sentry for Collaborative Robotics
The ST Robotics Workspace Sentry robot and area safety system are based on a small module that sends an infrared beam across the workspace. If the user puts his hand (or any other object) in the workspace, the robot stops using programmable emergency deceleration. Each module has three beams at different angles and the distance a beam reaches is adjustable. Two or more modules can be daisy chained to watch a wider area. "A robot that is tuned to stop on impact may not be safe. Robots where the trip torque can be set at low thresholds are too slow for any practical industrial application. The best system is where the work area has proximity detectors so the robot stops before impact and that is the approach ST Robotics has taken," states President and CEO of ST Robotics David Sands.
