faBrickation: Fast 3D Printing Using Bricks
Hasso-Plattner-Institut :
faBrickation is a new approach to rapid prototyping of functional objects, such as the body of a head-mounted display. The key idea is to save 3D printing time by automatically substituting sub-volumes with standard building blocks — in our case Lego bricks. When making the body for a head-mounted display, for example, getting the optical path right is paramount. Users thus mark the lens mounts as “high-resolution” to indicate that these should later be 3D printed. faBrickator then 3D prints these parts. It also generates instructions that show users how to create everything else from Lego bricks.

Prosthesis The Anti-Robot
From the Prosthesis projects Indiegogo campaign :
Prosthesis: the world's 1st, human controlled racing robot. Formula 1, meet the future. Let the races begin.
We are trying to save the future for the humans. With the relentless and unchecked automation of everything we do, we are trying to remind people that technology was invented to improve our quality of life, and that doesn't always mean just doing everything for you. Sometimes that means doing something really, really challenging. Sometimes that means taking on something that many have dreamed of, but no one has dared try before. Like building and learning to pilot a two story tall, 3500kg walking machine that you use your whole body to control, without computers to help you.... cont'd at homepage and Indiegogo .

Robonaut 2 Gets Legs
NASA :
NASA engineers are developing climbing legs for the International Space Station's robotic crew member Robonaut 2 (R2), marking another milestone in space humanoid robotics.
The legless R2, currently attached to a support post, is undergoing experimental trials with astronauts aboard the orbiting laboratory. Since its arrival at the station in February 2011, R2 has performed a series of tasks to demonstrate its functionality in microgravity.
These new legs, funded by NASA's Human Exploration and Operations and Space Technology mission directorates, will provide R2 the mobility it needs to help with regular and repetitive tasks inside and outside the space station. The goal is to free up the crew for more critical work, including scientific research.

Rex: A Single-board Computer With A Full OS That Is Designed For Robots
From the Rex Kickstarter :
Why do you want Rex?
There are two general classes of electronics used in robot hardware: microcontrollers (ex. Arduino) and single-board computers. Microcontrollers are great for projects that only require a single program to be run, quickly and without overhead, like controlling LEDs and motors. Single-board computers are great for anything you'd need a cheap, small computer for - like networking applications and image processing.
Advanced autonomous robots require the strengths of both. A system developed around Rex, being made specifically for robots, brings it all together in one nice little package in a way that has never been done before.
Hardware Specs:
Texas Instruments DM3730
1GHz 32-bit ARM Cortex-A8 Processor core
800MHz DSP core
512MB LPDDR RAM
USB Host port
MicroSD slot
Camera Module port
3.5mm Audio-in jack
3.5mm Audio-out jack
5V DC input for desktop development
Each Rex will come pre-installed with Alphalem OS, a FOSS custom linux distribution. It includes a core set of built-in device drivers - ones that we've hand-picked as being the most useful for robots (like USB WiFi adapters and cameras). We'll publish the list in a wiki on our website.
Here are the other main features:
An Arduino-style programming environment with support for multiple programming languages (C, C++, Python).
A special task manager called the Master Control Program (MCP).
An API for message passing in multi-process applications.
A standard Linux filesystem which will allow you to install just about any Linux software that can be cross-compiled for ARM.
Libraries for common processes such as I2C communication, face detection, and sensor reading.

The Factory-in-a-Day Project
From Factory-in-a-Day's page :
Small and medium-sized enterprises in Europe mostly refrain from using advanced robot technology. The EU-project Factory-in-a-Day aims to change this by developing a robotic system that can be set up and made operational in 24 hours and is flexible, leasable and cheap. The project has a budget of 11 million euros for four years, 7.9 million of which will be funded by the European Union as part of the FP7 programme ‘Factory of the Future’. The international consortium comprises 16 partners and the coordinating university is Delft University of Technology (TU Delft). The project will start on 8 October 2013 with a formal kick- off meeting in Delft.
Within 24 hours
The Factory-in-a-Day-project will provide a solution to these problems: a robot that can be set up and operational in 24 hours. SME companies can use the robot for a specific job and their staff can learn how to work closely together with the robot and thus optimize their production. “With the technological and organizational innovations of the Factory-in-a-Day project, we hope to fundamentally change the ways in which robots are used in the manufacturing world”, says project coordinator Martijn Wisse, Associate Professor at TU Delft. How does it work?
What will such an installation day look like? First of all, before the robot is actually taken to the SME premises, a system integrator analyzes which steps in the process can be taken over by the robot. In most cases the repetitive work is done by the robot while the human worker carries out the more flexible, accurate tasks and deals with problem- solving.
Customer-specific hardware-components are 3D-printed and installed on the grippers of the robot. The robot is then brought to the factory and set up, and any auxiliary components such as cameras are also set up in the unaltered production facilities. The robot will be connected to the machinery software through a brand-independent software system. After that, the robot is taught how to perform his set of tasks, for example how to grasp an object. Therefore, the operator will physically interact with the robot. A set of predefined skills will be available, rather like Apps for smart phones. Finally, the robot is operational and the human co-workers receive their training -- all in just 24 hours.

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.

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
