From Ali Osman Ulusoy, Octavian Biris, Joseph Mundy of Brown University: This paper presents a probabilistic volumetric frame- work for image based modeling of general dynamic 3-d scenes. The framework is targeted towards high quality modeling of complex scenes evolving over thousands of frames. Extensive storage and computational resources are required in processing large scale space-time (4-d) data. Existing methods typically store separate 3-d models at each time step and do not address such limitations. A novel 4-d representation is proposed that adaptively subdivides in space and time to explain the appearance of 3-d dynamic surfaces. This representation is shown to achieve compres- sion of 4-d data and provide efficient spatio-temporal pro- cessing. Theadvancesoftheproposedframeworkisdemon- strated on standard datasets using free-viewpoint video and 3-d tracking applications.... ( full paper )
From Navic209's youtube channel: Inspired by the Baxter robot, this arm can be trained to move with your own hands. Once the train button is pressed, you move the arm and gripper as needed while the Arduino stores the positions in EEPROM. After that the arm will replay the motion as needed.

According to AllThingsD Apple is in the process of buying PrimeSense. PrimeSense is the company that developed and licensed the hardware and chip design used in the original Kinect. This could have an effect on several low cost depth cameras including the ASUS Xtion which uses PrimeSense hardware or the $200 developer camera sold directly from PrimeSense . Their online store is still open but who know for how long.
IEEE Spectrum: As cool as quadrotors are, in most cases they're simply not as good as helicopters. Because of the way they're designed (with four small rotors instead of one big one), they're less powerful, less efficient, and less maneuverable. The power and efficiency issues come from the fact that one big rotor generates more lift per aircraft footprint than four small rotors, and as for maneuverability, a helicopter that can alter rotor pitch instantly will always outmaneuver a quadrotor that can only control blade speed. Seriously, try doing this with a quadrotor. So, the thing that quadrotors have going for them is that they're simple. Helicopters have complex main rotor heads, with shafts and bearings and linkages all over the place, while quadrotors just have four motors and that's it. The University of Queensland researchers came up with a "Y4" configuration that aims to take all the good bits of helicopters and make them as simple as quadrotors. I'm just going to start calling this new design a triquad. Keep in mind that this is still a quadrotor: it just had things shifted around a little bit. Almost all of the triquad's lift comes from its big main fixed-pitch rotor, located at the center of the "Y" (pictured below). The three little fixed-pitch rotors in the "Y" configuration are angled (at a fixed 45 degrees) to provide counter-torque (which they do slightly more efficiently than a helicopter tail rotor) along with pitch and roll control. Here's how the control works... cont'd at IEEE Spectrum Follow up discussions: DIY Drones post and discussion. Hackernews post.
Harvest Automation robots are designed to work around the clock, they never need a break, and can handle the most tedious and repetitive work on a Nursery or Greenhouse operation with consistent accuracy and on-time performance.
TORC's unmanned ground vehicle (UGV) conversion kits, which maintain the ability for optionally manned operation, offer the proven capabilities and modularity necessary for AFRL to scale from one prototype to production quantity.
CoaXpress and MatLab integration offer options where previously none existed. The ability to have a controllable high speed camera at distances greater than 7m wasn't a possibility before, without the use of extenders and other potential hardware failures.

REIKU's Cable Saver™ Solution eliminates downtime, loss of revenue, expensive cable and hose replacement costs, maintenance labour costs. It's available in three sizes 36, 52 and 70 mm. All of the robots cables and hoses are protected when routed through the Cable Saver™ corrugated tubing. The Cable Saver™ uses a spring retraction system housed inside the Energy Tube™ to keep this service loop out of harms way in safe location at the rear of the Robot when not required. The Cable Saver™ is a COMPLETE solution for any make or model of robot. It installs quickly-on either side of the robot and has been tested to resist over 15 million repetitive cycles.
