Optimal Actuator In MIT's Cheetah Robot
From Biomimetics MIT Cheetah project:
The high speed legged locomotion of the MIT Cheetah requires high accelerations and loadings of the robot’s legs. Because of the highly dynamic environmental interactions that come with running, variable impedance of the legs is desirable; however, existing actuation strategies cannot deliver. Typically, electric motors achieve their required torque output and package size through high gear ratios. High ratios limit options for control strategies. For example, closed loop control is limited to relatively slow speed dynamics. Series elastic actuation adds additional actuators and increases system complexity and inertia. We believed a better option existed. In the end, we developed a novel actuator, optimal in many applications... ( project homepage ) ( full published article )

Microsoft Deploys Autonomous Robot Security Guards in Silicon Valley Campus
From Extremetech:
The K5, built by the Californian company Knightscope, is billed rather euphemistically as an “autonomous data machine” that provides a “commanding but friendly physical presence.” Basically, it’s a security guard on wheels. Inside that rather large casing (it’s 5 foot tall!) there are four high-def cameras facing in each direction, another camera that can do car license plate recognition, four microphones, gentle alarms, blaring sirens, weather sensors, and WiFi connectivity so that each robot can contact HQ if there’s some kind of security breach/situation. For navigating the environment, there’s GPS and “laser scanning” (LIDAR I guess). And of course, at the heart of each K5 is a computer running artificial intelligence software that integrates all of that data and tries to make intelligent inferences...

Deep Visual-Semantic Alignments for Generating Image Descriptions
Because of the Nov. 14th submission deadline for this years IEEE Conference on Computer Vision and Pattern Recognition (CVPR) several big image-recognition papers are coming out this week:
From Andrej Karpathy and Li Fei-Fei of Stanford:
We present a model that generates free-form natural language descriptions of image regions. Our model leverages datasets of images and their sentence descriptions to learn about the inter-modal correspondences between text and visual data. Our approach is based on a novel combination of Convolutional Neural Networks over image regions, bidirectional Recurrent Neural Networks over sentences, and a structured objective that aligns the two modalities through a multimodal embedding. We then describe a Recurrent Neural Network architecture that uses the inferred alignments to learn to generate novel descriptions of image regions. We demonstrate the effectiveness of our alignment model with ranking experiments on Flickr8K, Flickr30K and COCO datasets, where we substantially improve on the state of the art. We then show that the sentences created by our generative model outperform retrieval baselines on the three aforementioned datasets and a new dataset of region-level annotations...

Project Beyond: 360° 3D Camera
From Project Beyond/Samsung:
Today we offer a sneak preview of Project Beyond,the world’s first true 3D 360˚ omniview camera. Beyond captures and streams immersive videos in stunning high-resolution 3D, and allows every user to enjoy their viewing experience in the way they see fit. It offers full 3D reconstruction in all directions, using stereo camera pairs combined with a top-view camera to capture independent left and right eye stereo pairs.
Project Beyond uses patent-pending stereoscopic interleaved capture and 3D-aware stitching technology to capture the scene just like the human eye, but in a form factor that is extremely compact. The innovative reconstruction system recreates the view geometry in the same way that the human eyes see, producing unparalleled 3D perception.
Project Beyond is not a product, but one of the many exciting projects currently being developed by the Think Tank Team, an advanced research team within Samsung Research America. This is the first operational version of the device, and just a taste of what the final system we are working on will be capable of. Once complete, we hope to deploy Project Beyond around the world to beautiful and noteworthy locations and events, and allow users to experience those locations as if they were really there. The camera system can stream real time events, as well as store the data for future viewing... ( website )
