ROBOCHOP: Interactive Installation Allows Internet Users Worldwide to Remotely Control a Pop-up Robotic Plant
From Clemens Weisshaar and Reed Kram:
From March 16-20, 2015 internet users and visitors to CODE_n (Hall 16) at CeBit in Hanover will be able to use an online app connected to the ROBOCHOP installation to design and fabricate a piece of furniture in real time.
The ROBOCHOP interface lets participants instruct a robotic arm to grab and sculpt a prefabricated 40 x 40 x 40cm durable foam cube using a floor mounted hot wire tool to create the object of their choice.
The pop-up robotic plant has been conceptualised, coded and built by KRAM/WEISSHAAR. ROBOCHOP features a needle gripper as the robot’s hand, coaxial cooling of the cutting wire and sensors to measure the wire’s tension and provide direct feedback to the system. This harnesses the robot’s brute force and allows it to sculpt hundreds of unique objects consecutively with elegance and precision. Once manufacturing is complete, each custom object is packaged and posted to the user anywhere in the world entirely free of charge... ( full release ) ( homepage )

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 )

ArduIMU V4: An Arduino Based Integrated Measurement Unit
Kickstarter for version 4 of ArduIMU:
Initially, the ArduIMU project was started as an open source project by 3DRobotics in 2007 to create an inertial measurement unit based on the Arduino™. We contributed to the software development of that project, but, the initial ArduIMU was meant to be used solely as an inertial measurement unit. We want to do better than that; so we developed a brand new platform with other sensors such as a barometer, relative humidity sensor, and light sensor. We also included wireless communication capabilities as well an SD card for data logging and storage. Since then, we have gone through many revisions, adding even more sensors and functions which are present in the latest ArduIMU V4. With this new augmented and improved sensor board we are redefining the term IMU. We proudly present our Arduino™ based Integrated Measurement Unit: the ArduIMU V4... ( cont'd )
High Speed Bipedal Robot Running Using High Speed Visual Feedback
From University of Tokyo:
ACHIRES is composed of high-speed vision and high-speed actuators to achieve instantaneous recognition and behavior. The similar technologies are used in our Janken (Rock Paper Scissors) Robot. High-speed vision detects the state of the biped robot including the timing of landing at 600 fps. The biped mechanism with the leg length of 14 cm is set to run in the sagittal plane. At present, the running velocity reaches 4.2 km/h. Simple control based on high-speed performance of sensory-motor system enables the biped robot to stably run without falling, unlike computationally expensive ZMP-based control which is commonly used for balance. The aerial posture is recovered to compensate for the deviation from the stable trajectory using high-speed visual feedback.
We also address a task of somersaulting. While running, the robot takes a big swing with one foot and jumps. After takeoff, both legs are controlled to curl up for high-speed rotation in the air. ACHIRES is going to be improved to push the envelope while demonstrating various biped locomotion tasks... ( cont'd )

Ino: Command Line Toolkit for Arduino Hardware
Ino tools webpage :
Ino is a command line toolkit for working with Arduino hardware
It allows you to:
Quickly create new projects
Build a firmware from multiple source files and libraries
Upload the firmware to a device
Perform serial communication with a device (aka serial monitor)
Ino may replace Arduino IDE UI if you prefer to work with command line and an editor of your choice or if you want to integrate Arduino build process to 3-rd party IDE.
Ino is based on make to perform builds. However Makefiles are generated automatically and you’ll never see them if you don’t want to.
Features
Simple. No build scripts are necessary.
Out-of-source builds. Directories with source files are not cluttered with intermediate object files.
Support for *.ino and *.pde sketches as well as raw *.c and *.cpp .
Support for Arduino Software versions 1.x as well as 0.x.
Automatic dependency tracking. Referred libraries are automatically included in the build process. Changes in *.h files lead to recompilation of sources which include them.
Pretty colorful output.
Support for all boards that are supported by Arduino IDE.
Fast. Discovered tool paths and other stuff is cached across runs. If nothing has changed, nothing is build.
Flexible. Support for simple ini-style config files to setup machine-specific info like used Arduino model, Arduino distribution path, etc just once.

Raspberry Pi Model B+
From Eben Upton, Raspberry Pi Founder:
This isn’t a “Raspberry Pi 2″, but rather the final evolution of the original Raspberry Pi. Today, I’m very pleased to be able to announce the immediate availability, at $35 – it’s still the same price, of what we’re calling the Raspberry Pi Model B+.
The Model B+ uses the same BCM2835 application processor as the Model B. It runs the same software, and still has 512MB RAM; but James and the team have made the following key improvements:
More GPIO. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model B.
More USB. We now have 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behaviour.
Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.
Lower power consumption. By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W.
Better audio. The audio circuit incorporates a dedicated low-noise power supply.
Neater form factor. We’ve aligned the USB connectors with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes... ( cont'd )
Intro to Shape Memory Alloy Actuation Using Flexinol
From Jie Qi's projects page:
Shape memory alloys (SMAs) are metals that change shape when heated up. They are wonderful actuators in that they are light, silent and can be "turned on" by simply running current through. The shape that they change to can also be set, though this process is a bit more tricky. Flexinol is a particular brand of nitinol, which is an SMA made of nickel and titanium, and is pre-set to contract about 10% of its original length when heated.
In my projects, I generally used the 0.006" to 0.01" diameter, High-Temp wires.
Since Flexinol draws a lot of current (about 300mA for the diameters I used), you need a strong power supply like a wall supply or a good lithium-ion battery. I've used from 3.7V up to 6V (any more and my Flexinol wires would start overheating). To turn the Flexinol on, I would simply short the ends of the wire to the power. For digital control, I used a standard MOSFET circuit which is a digital switch that can be turned on and off using a microcontroller... ( cont'd )

Dynatect Automated Machine Safety Roll-Up Doors
Need to increase safety? Are you using light curtains? Is space a concern?
Dynatect's Gortite® VF Automated Machine Safety Door combines safety technology, speed, and a physical barrier to isolate hazardous operations. Use of a physical barrier with safety sensors can save up to 30 square feet of manufacturing space. Using the ANSI minimum safety distance formula, the Gortite® VF Door limits the depth penetration factor and average approach speed, allowing closer location of the safeguarding device. Unlike light curtains, which can't contain process hazards, an automated machine safety door can isolate common workplace debris. This physical barrier is designed to contain process driven hazards such as weld sparks, UV flash, and light debris. Thus, the operator can maintain closer proximity to the work area improving ergonomics and productivity.
