Algorithm that harnesses data from a new sensor could make autonomous robots more nimble.
MIT paper from Andrea Censi and Davide Scaramuzza:
The agility of a robotic system is ultimately limited by the speed of its processing pipeline. The use of a Dynamic Vision Sensors (DVS), a sensor producing asynchronous events as luminance changes are perceived by its pixels, makes it possible to have a sensing pipeline of a theoretical latency of a few microseconds. However, several challenges must be overcome: a DVS does not provide the grayscale value but only changes in the luminance; and because the output is composed by a sequence of events, traditional frame-based visual odometry methods are not applicable. This paper presents the first visual odometry system based on a DVS plus a normal CMOS camera to provide the absolute brightness values. The two sources of data are automatically spatiotemporally calibrated from logs taken during normal operation. We design a visual odometry method that uses the DVS events to estimate the relative displacement since the previous CMOS frame by processing each event individually. Experiments show that the rotation can be estimated with surprising accuracy, while the translation can be estimated only very noisily, because it produces few events due to very small apparent motion ...

Leap Motion V2 Tracking
From Leap Motion's developer blog :
V2 retains the speed and positional accuracy found in V1, but the software also now tracks the actual joints and bones inside each of the user’s fingers. This leads to some immediate benefits over V1:
Finger and hand labels – every finger, hand, and joint now has anatomical labels like ‘pinky’, ‘left hand’, and ‘proximal phalanges’
Occlusion robustness – fingers are tracked even when they’re not seen by the controller, as might happen if you turned your hands completely vertically or intertwined the fingers of your left and right hands
Massively improved resistance to ambient infrared light – sunlight, powerful halogens, etc.
Much more granular data for developers about the user’s hands and fingers – 27 dimensions per hand, in addition to special parameters like grab/pinch APIs

UBR-1 Available for Purchase
From Unbounded Robotics:
Beginning today, UBR-1 is available for purchase. To order your own state-of-the-art mobile manipulation platform please contact sales@unboundedrobotics.com.
The majority of requests we have had to date have been for the UBR-1 pro model, so we have decided to focus on and ship only one model. The cost of the UBR-1 is $50,000 and will include the newest Hokuyo UST-20LX scanning laser. UBR-1 now offers a higher maximum speed, a state of the art laser scanner, more RAM, and a larger hard drive capacity. In addition to the UBR-1 we are happy to announce that we will also be offering a ROS Ready Computer Package to make setting up your robot even easier. This package includes a computer with Ubuntu and ROS pre-installed, and a wireless router pre-configured to connect your robot and computer.
We are planning to start shipping robots to their destinations in late August... ( cont'd )

New Computer Vision Project Can Solve reCAPTCHAs With Over 99% Accuracy
From Google Online Security Blog:
Translating a street address to an exact location on a map is harder than it seems. To take on this challenge and make Google Maps even more useful, we’ve been working on a new system to help locate addresses even more accurately, using some of the technology from the Street View and reCAPTCHA teams.
This technology finds and reads street numbers in Street View, and correlates those numbers with existing addresses to pinpoint their exact location on Google Maps.
We show that this system is able to accurately detect and read difficult numbers in Street View with 90% accuracy.
Turns out that this new algorithm can also be used to read CAPTCHA puzzles—we found that it can decipher the hardest distorted text puzzles from reCAPTCHA with over 99% accuracy... ( cont'd ) ( full technical paper )

Raspberry Pi Compute Module
From Raspberry Pi Foundation :
The compute module contains the guts of a Raspberry Pi (the BCM2835 processor and 512Mbyte of RAM) as well as a 4Gbyte eMMC Flash device (which is the equivalent of the SD card in the Pi). This is all integrated on to a small 67.6x30mm board which fits into a standard DDR2 SODIMM connector (the same type of connector as used for laptop memory*). The Flash memory is connected directly to the processor on the board, but the remaining processor interfaces are available to the user via the connector pins. You get the full flexibility of the BCM2835 SoC (which means that many more GPIOs and interfaces are available as compared to the Raspberry Pi), and designing the module into a custom system should be relatively straightforward as we’ve put all the tricky bits onto the module itself.
So what you are seeing here is a Raspberry Pi shrunk down to fit on a SODIMM with onboard memory, whose connectors you can customise for your own needs.
The Compute Module is primarily designed for those who are going to create their own PCB. However, we are also launching something called the Compute Module IO Board to help designers get started.
