In the last few months various hackers and enthusiasts have been jumping on board the Leap Motion devices and having them do their bidding. One interesting example of this has been demonstrated by Yu Jiang Tham - his device is a robot arm that can mimic the motion of a user's arm by capturing the position from a Leap Motion device and converting it to servo controls via an Arduino. Doing so is not a beginners' project, however all the physics theory, code and notes have been included to you can replicate it. Which could be quite worthwhile or really fun, for example:
For a further development of this project, consider creating a link from the Leap Motion to a remote arm - thus controlling it from a distance. This isn't too far from reality, where doctors can remotely conduct operations using more precise versions of this technology. Nevertheless, to find out more and create one yourself, visit Yu Jiang's website. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're new to Arduino and want to join the fun, the first step is a solid board for your projects - our Freetronics Eleven - the Arduino-Uno compatible with low-profile USB socket, onboard prototyping space and easy to view LEDs:
