Dynamic Probabilistic Volumetric Models

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 )

Trainable Arduiono Arm

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.   Youtube channel Source on Github Additional projects

PrimeSense Reportedly Aquired By Apple

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.

Triquad

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.

Air Force Research Lab Uses TORC's Robotic Conversion Kits for Robotic Assault-Zone Survey Vehicle

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.

Highspeed Frame Capture Interface With MatLab

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.

S4A: Scratch modification for Arduino

S4A: Scratch for Arduino (S4A) is a modified version of Scratch , ready to interact with Arduino boards. Supported boards S4A works with Arduino Diecimila, Duemilanove and Uno. Other boards haven't been tested, but they may also work. Connectivity Components have to be connected in a particular way. S4A allows for 6 analog inputs (analog pins), 2 digital inputs (digital pins 2 and 3), 3 analog outputs (digital pins 5, 6 and 9), 3 digital outputs (pins 10, 11 and 13) and 4 special outputs to connect Parallax continuous rotation servomotors (digital pins 4, 7, 8 and 12). You can manage a board wirelessly by attaching an RF module to it, such as Xbee. S4A allows you to control as many boards as USB ports you have. Compatibility S4A is backwards compatible with Scratch, so you can open Scratch projects in it. However, you won't be able to share your projects on the Scratch community website because doing so goes against the Scratch terms of use. Take in account that this compatibility doesn't work both ways, so you won't be able to open an S4A project from within the original Scratch. Using a PicoBoard along with an Arduino board is also supported... cont'd
