A Robotic Wheelchair Able To Climb Steps
A demo of Chiba Institute of Technology's wheel chair concept:
"If a sensor detects a step, the robot calculates whether it can lift that leg. It can't raise its wheels right away, so the steering system at the rear makes preparatory motions to gain stability. When the wheels can be raised stably, the robot lifts its legs."

Espresso Book Machine
The Espresso Book Machine makes a perfect-bound paperback book virtually identical to the publisher’s original in a matter of minutes. The user chooses a digital file via the EspressNet software system, either at the physical EBM, or remotely via the Internet (users can also bring their own files in person: on CD’s, flash drives, etc.). The EBM uses PDF files for the book block and the cover. A high-speed Xerox 4112 Copier/Printer prints the pages of the book – the book block. The printer uses standard US letter-size (8.5” x 11”) or A4 paper stock. A high-speed Xerox 4112 Copier/Printer prints the pages of the book – the book block. The printer uses standard US letter-size (8.5” x 11”) or A4 paper stock. A rotating wheel applies a thin layer of heat-activated glue over the milled edge. The clamp then moves the book block down to the cover, which waits on the binding table. The EBM uses special pneumatics and clamps to press the cover against the spine and around the book block. This produces a traditional “perfect-bound” book.
Human Support Robot From Toyota
Toyota Motor Corporation has developed a human support robot (HSR) prototype to assist independent home living for persons with limited arm or leg mobility. Aiming to improve quality of life, Toyota has developed the HSR prototype in cooperation with the Japan Service Dog Association to identify the needs and desires of individuals with limited limb mobility, and developed functions focused around picking up dropped objects, retrieving items, and communicating with family members and caregivers. In 2011, TMC conducted in-home trials using the robot with individuals with limb disabilities in cooperation with the Foundation for Yokohama Rehabilitation Service and incorporated user feedback into development.
Stack Exchange Teams Up With US Patent Office To Crowd Source Prior Art
The new America Invents Act came into effect on September 16, it lets ordinary people provide feedback on patent applications. The US Patent Office and the question/answer resource Stack Exchange are teaming up to create AskPatents . AskPatents allows allows anyone to participate in the patent examination process.
Joel Spolsky, co-founder of Stack Exchange:
"Ask Patents is a collaborative effort, neatly tagged by keywords and classification, and searchable by patent application number. It is inspired by a research project called Peer To Patent, run out of New York Law School. That pilot project, created by Professor Beth Noveck, proved very successful at identifying prior art that the USPTO wouldn’t otherwise have known about.
Citizen volunteers and other interested parties will be able to ask about applications that they think are suspicious. Others can answer, identifying possible prior art, and using our upvote/downvote feature to rate any examples of prior art that other people found.
The USPTO, complying with the new law, will also provide an online system for submitting prior art. We’re also integrating with Google Patent Search, so every patent application on Google will include a link to discussion on Stack Exchange. Google has also implemented an algorithmic prior art search utility that will be helpful to site participants.
On Ask Patents, participants can also ask and answer questions about the nuances of patent law or about specific patent applications.
Collectively, we’re building a crowd-sourced worldwide detective agency to track down and obliterate bogus patent applications. Over time, we hope that the Patent Stack Exchange will mitigate the problems caused by rampant patent trolling. It’s not a complete fix, but it’s a good start."
Rethink Robotics releases Baxter, its Manufacturing robot
Baxter, is six feet tall, 300 pounds, and a robot. For a hulking machine, Baxter is remarkably expressive. A pair of eyes on the screen that serves as a face stare down as the robot picks up plastic components, look concerned when it makes a mistake, and direct its glance at its next task when one is finished. It's cute. But the real point of these expressions is that they let workers nearby know instantly if Baxter is performing appropriately, and they provide clues to what it is about to do next. Even more amazing, when Baxter is done with one task, a fellow worker can simply show the robot how to start another. "Almost anyone, literally, can in very short order be shown how to program it," says Chris Budnick, president of Vanguard Plastics. "It's a matter of a couple of minutes."
Baxter is the first of a new generation of smarter, more adaptive industrial robots. Conventional industrial robots are expensive to program, incapable of handling even small deviations in their environment, and so dangerous that they have to be physically separated from human workers by cages. So even as robotics have become commonplace in the automotive and pharmaceutical industries, they remain impractical in many other types of manufacturing. Baxter, however, can be programmed more easily than a Tivo and can deftly respond to a toppled-over part or shifted table. And it is so safe that Baxter's developer, Rethink Robotics, which loaned Baxter to Vanguard Plastics, believes it can work seamlessly alongside its human coworkers.
New AlphaDog Field Testing Footage
New footage of AlphaDog, the DARPA Legged Squad Support System (LS3) originally designed by Boston Dynamics.
The goal of the LS3 program is to demonstrate that a legged robot can unburden dismounted squad members by carrying their gear, autonomously following them through rugged terrain, and interpreting verbal and visual commands.
QBotix Solar Tracking System
From todays press release:
QBotix today unveiled the QBotix Tracking System™ (QTS), a comprehensive dual-axis tracking system that employs rugged, intelligent and mobile robots to dynamically operate solar power plants and maximize energy output.
The solar panels are installed on QBotix designed mounting systems that don't have any individual motors and are optimized for cost, strength, durability and installation simplicity. The robots travel on a track and adjust each mounting system to optimally face the sun in succession. Each robot replaces hundreds of individual motors and controllers found on conventional tracking systems. The embedded intelligence and data communication capabilities of each autonomous robot optimize power plant performance and enables detailed operational knowledge at an unprecedented level.
QTS is now available for commercial deployments.

A 1998 presentation by computer scientist Guy Steele, co-designer of the Scheme programming language. If you are at all interested in computer language design and theory you owe it to yourself to watch at least the first 10 minutes of the video. It might be the "Sixth Sense" of computer language design presentations.
Disney's 'Physical Face Cloning'
Disney Research released info on research they've been doing for simulating, and fabricating synthetic skin for an animatronics character that mimics the face of a given subject and its expressions. The process starts with measuring the elastic properties of a material used to manufacture synthetic soft tissue. Given these measurements they use physics-based simulation to predict the behavior of a face when it is driven by the underlying robotic actuation. Next, we capture 3D facial expressions for a given target subject.

A New Programming Language For Image-processing Algorithms
Halide is a new programming language designed to make it easier to write high-performance image processing code on modern machines. Its current front end is an embedding in C++. Hardware targets include x86-64/SSE, ARM v7/NEON, and CUDA. Created by researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) Halide was used to rewrite several common image-processing algorithms whose performance had already been optimized by seasoned programmers. The Halide versions were typically about one-third as long but offered significant performance gains — two-, three-, or even six-fold speedups. In one instance, the Halide program was actually longer than the original — but the speedup was 70-fold. The paper is available here and the source will be posted within the next couple of days on github and the projects home here .
