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 )

I am traveling from Halifax, Nova Scotia to Victoria, British Columbia this summer. As you may have guessed, robots cannot get driver’s licences yet, so I’ll be hitchhiking my entire way... ( 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.

Parallella: $119 Parallel Computing Platform with 16-core Epiphany chip
Parallella Computer Specifications:
The Parallella platform is an open source, energy efficient, high performance, credit-card sized computer based on the Epiphany multicore chips developed by Adapteva. This affordable platform is designed for developing and implementing high performance, parallel processing applications developed to take advantage of the on-board Epiphany chip. The Epiphany 16 or 64 core chips consists of a scalable array of simple RISC processors programmable in C/C++ connected together with a fast on chip network within a single shared memory architecture...

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 )

By far, one of the most inspirational and impressive projects thats come from the 3D printing/DIY community has been the work were seeing on open-source assistive devices, and one online organization that is playing a major role in making this happen is e-NABLE, a group started by Dr. Jon Schull of Rochester Institute of Technology.
BugJuggler: Project to build 70ft tall robot that juggles cars
Project Overview:
BugJuggler will use a diesel engine to generate hydraulic pressure. An operator located in the robot’s head will be able to control its motions using a haptic feedback interface connected to high-speed servo valves. Hydraulic accumulators - essentially storage batteries for hydraulic fluid - will allow for the rapid movement required for the robot to juggle cars or other large, heavy objects.
The first stage of the BugJuggler project will be construction of a working 8ft tall single arm proof-of-principle juggler able to toss and catch a 250lb mass... ( cont'd )
Intel's 3-D Printed Robot "Jimmy"
From Wired:
Intel describes Jimmy as a research robot, but a less sophisticated version of the adorable droid will go on sale later this year for $1,600. The caveat is that you will have to 3D print your Jimmy. The 3D printing blueprints will be available without charge, but to construct the robot you will also need to purchase a kit from Intel that will contain all the parts of Jimmy that aren't printable, including motors and an Intel Edison processor..
