High Speed Bipedal Robot Running Using High Speed Visual Feedback
From University of Tokyo:
ACHIRES is composed of high-speed vision and high-speed actuators to achieve instantaneous recognition and behavior. The similar technologies are used in our Janken (Rock Paper Scissors) Robot. High-speed vision detects the state of the biped robot including the timing of landing at 600 fps. The biped mechanism with the leg length of 14 cm is set to run in the sagittal plane. At present, the running velocity reaches 4.2 km/h. Simple control based on high-speed performance of sensory-motor system enables the biped robot to stably run without falling, unlike computationally expensive ZMP-based control which is commonly used for balance. The aerial posture is recovered to compensate for the deviation from the stable trajectory using high-speed visual feedback.
We also address a task of somersaulting. While running, the robot takes a big swing with one foot and jumps. After takeoff, both legs are controlled to curl up for high-speed rotation in the air. ACHIRES is going to be improved to push the envelope while demonstrating various biped locomotion tasks... (cont'd)

Unbounded Robotics to Shut Down Due to Issues With Willow Garage Spin-Off Agreement
From Evan Ackerman at IEEE Spectrum:
IEEE Spectrum has learned that Unbounded Robotics, a spin-off of Willow Garage that developed the UBR-1 mobile manipulator, is currently "in the process of shutting down." The UBR-1 is no longer for sale.
Recently, a source (who asked not to be named) forwarded us an email from Unbounded Robotics CEO Melonee Wise. Our source received the message after requesting a quote for a UBR-1 robot:
"Unfortunately Unbounded Robotics is in the process of shutting down due to issues with our Willow Garage spin off agreement that prevents us from raising series A investment. Unbounded Robotics is no longer selling the UBR-1.... (cont'd)

Large Scale Visual Recognition Challenge 2014
Introduction:
This challenge evaluates algorithms for object detection and image classification at large scale. This year there will be two competitions:
A PASCAL-style detection challenge on fully labeled data for 200 categories of objects, and
An image classification plus object localization challenge with 1000 categories.
NEW: This year all participants are encouraged to submit object localization results; in past challenges, submissions to classification and classification with localization tasks were accepted separately.One high level motivation is to allow researchers to compare progress in detection across a wider variety of objects -- taking advantage of the quite expensive labeling effort. Another motivation is to measure the progress of computer vision for large scale image indexing for retrieval and annotation... (rules and results)
New York Times article:
Started in 2010 by Stanford, Princeton and Columbia University scientists, the Large Scale Visual Recognition Challenge this year drew 38 entrants from 13 countries. The groups use advanced software, in most cases modeled loosely on the biological vision systems, to detect, locate and classify a huge set of images taken from Internet sources like Twitter. The contest was sponsored this year by Google, Stanford, Facebook and the University of North Carolina.
Contestants run their recognition programs on high-performance computers based in many cases on specialized processors called G.P.U.s, for graphic processing units.
This year there were six categories based on object detection, locating objects and classifying them... (cont'd)
Rising Colorspace
Rising Colorspace is a site-specific installation for “Metropol Park“ at Köllnischer Park 6-7 in Berlin. It is the third systemic robot installation of our colorspace series.
A robot draws his rising movements as bowlike lines onto a shiny metallic wall. All turns and falling movements are left out. Thereof derives a wickerwork of lines in rich botanic coloration. This condenses to a colorspace. Each line grows like a bending culm and modulates the colorspace after a daily color-protocol."¨ Rising Colorspace is an evolving system continuously overwriting itself... (cont'd)

T100 Underwater Thruster Designed for Marine Robotics
From BlueRobotics' Kickstarter:
An efficient, rugged, affordable underwater thruster to propel the future of marine robotics and ocean exploration. ($100 dollars a thruster, est delivery Nov 2014)
The T100 is made of high-strength, UV resistant polycarbonate injection molded plastic. The core of the motor is sealed and protected with an epoxy coating and it uses high-performance plastic bearings in place of steel bearings that rust in saltwater. Everything that isn’t plastic is either aluminum or high-quality stainless steel that doesn’t corrode.
A specially designed propeller and nozzle provides efficient, powerful thrust while active water-cooling keeps the motor cool. Unlike other thrusters, our design doesn’t have any air- or oil-filled cavities - water flows freely through all parts of the motor while it's running. That means it can go deep in the ocean and handle extreme pressures.
The thruster is easy to use: just connect the three motor wires to any brushless electronic speed controller (ESC) and you can control it with an RC radio or a microcontroller. It's usable with Arduino, ArduPilot, Raspberry Pi, BeagleBone, and many other embedded platforms... (kickstarter)
