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 that's come from the 3D printing/DIY community has been the work we're 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.
With the help of a KUKA robot, a research project at the University of Stuttgart gave rise to a wooden pavilion that is characterized by its particular capabilities and efficient use of resources. The unusual pavilion can be visited at the State Garden Festival in Schwäbisch Gmünd, Germany until 12 October.

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 )

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.
