REMUS SharkCam: The Hunter and the Hunted
From Woods Hole Oceanographic Institution's Vimeo page:
In 2013, a team from the Woods Hole Oceanographic Institution took a specially equipped REMUS "SharkCam" underwater vehicle to Guadalupe Island in Mexico to film great white sharks in the wild. They captured more than they bargained for.

Robot With Broken Leg Learns To Walk Again In 2 Minutes
From Medium:
Today, Antoine Cully at the Sorbonne University in Paris and a couple of pals say they’ve developed a technique that allows a damaged robot to learn how to walk again in just a few seconds. They say their work has important consequences for the reliability and robustness of future robots and may also provide some insight into the way that animals adapt to injury as well... ( cont'd )

Quoc Le's Lectures on Deep Learning
Gaurav Trivedi has put together a landing page with all of Quoc Le’s recent lecture series and accompanying resources:
Dr. Quoc Le from the Google Brain project team (yes, the one that made headlines for creating a cat recognizer) presented a series of lectures at the Machine Learning Summer School (MLSS ’14) in Pittsburgh this week. This is my favorite lecture series from the event till now and I was glad to be able to attend them... ( cont'd with all videos )
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 )
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 )
A Robot Valet Will Park Your Car at This German Airport
Last week, Düsseldorf airport (DUS) introduced robot valets to take the hassle out of parking for travelers. Travelers can leave their cars at the arrival level of the ParkingPLUS structure. As they leave, they confirm on a touch-screen that no one is in the car.
The robot valet, nicknamed "Ray," takes it from there. The robot measures the vehicle, picks it up with a forklift-like system, and takes it to the back area, where it will position it in one of the 249 parking spots reserved for automated valets.
The machine is capable of carrying standard cars weighing up to 3.31 tons. The robot valet is even connected to the airport's flight data system, and by checking customer trip data with the database, Ray knows when the customer will return for the vehicle. A traveler can note any itinerary changes in a parking app, which is available for iOS and Android.

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..

Blocky: A Graphic Programming Environment for ROS
From the robotics laboratory of Ben Gurion University:
The main goal of this project it to allow users with only basic background in programming to develop software for controlling robots using ROS, this by developing a graphical interface that is user-friendly and convenient for programing to ROS. Researchers or other users often encounter a problem when come to develop a robot, they lack extensive background in programming and most of the times comes from a slightly different backgrounds (such as mechanical engineering or electrical engineering) which requires them long-term learning or rely on other professionals. The graphical interface shown in this project suggests that a researcher or a user to control a robot in a simple and more intuitive way without having to spend weeks learning the principles of ROS and without having to learn to program at all.
This project product is a web-content, generic, open source, extensible and user-friendly program that helps in the development of a ROS based robot, while providing tools for correct developing... ( cont'd )
