Controlling A Quadcopter With A Leap Motion

November 18, 2012 by Brian Benchoff 13 Comments

A few folks over at National Instruments going under the name LabVIEW Hacker have gotten their hands on a Leap Motion dev kit. The Leap is an interesting little input device designed to track fingertips in 3D space, much like a Kinect but at much higher resolution. Needing something to show off their LabVIEW prowess, these guys controlled their office AR Drone with the Leap, making a quadcopter controller that is completely touchless.

Building on their previous AR Drone hack, the LabVIEW team spent the better part of a day adding wrappers around the Leap SDK and adding in control for their RC quadcopter. Now, simply by moving their fingertips over the Leap sensor, they can control their office quadrotor using a very high-resolution 3D scanner.

Using UAVs To Find Mannequins Lost In The Outback

October 7, 2012 by Brian Benchoff 40 Comments

Every other year the Australian Research Center for Aerospace Automation, the government of Queensland, Australia and other government and research institutions hold a contest to develop technology for unmanned aerial vehicles for the wastes of central Australia. Canberra UAV – a group of autonomous drone enthusiasts from the Make, Hack, Void hackerspace – took part in this UAV challenge this year. They ended up with one of the most successful UAVs to every compete, and while they didn’t quite finish the competition they were one of the most successful entries to date.

The goal of the Search and Rescue Outback Challenge is to take off from a landing strip, search for a mannequin named Outback Joe, and deliver 500 ml of life-giving water via air drop. Out of 72 teams entered in to this year’s Outback Challenge, only 6 were allowed to take off – safety restrictions, don’t you know – and all but two hadn’t been destroyed via ‘rapid, unplanned descent’ during qualifications.

UAV Canberra was the only team able to search the entire 5 nautical mile radius search area with their cameras and find Outback Joe. Contest judges gave them permission to drop their payload, but unfortunately the bottle of water was snagged on the engine.

In the many iterations of the Search and Rescue Outback Challenge, UAV Canberra is only the second team to locate a mannequin in the outback, and the first to do it autonomously. A shame, then, that they were unable to claim a victory, but we’ll look forward to their entry in the next Search and Rescue competition.

You can check out a few videos of the Canberra UAV team’s flights after the break.

Autonomous Plane? Quadrotor? Both? Meet The ATMOS!

September 4, 2012 by Jeremy Cook 12 Comments

If you’ve been trying to decide between building an autonomous quadcopter or a fixed wing UAV, you may not have to choose anymore. [Team ATMOS] from Tu Delft University in the Netherlands, has developed a UAV that can autonomously transition from quadcopter flight to that of a fixed-wing aircraft. Although the world has seen several successful examples of transitioning-flight or VTOL aircraft, team [ATMOS] claims to have made the first autonomous transition of this type of craft.

This UAV was featured in their school newspaper, which provides a write-up about the work that went into creating this hybrid UAV. When you’re done with that, be sure to check out the two videos after the break. The first shows the [ATMOS] taking off vertically and flying off as a flying-wing fixed aircraft. The second video shows this and other UAVs in the [DARPA] competition that it was designed for. Fast forward to 2:24 to see this aircraft do a fly-by.

Extending The Range Of The AR Drone, 2 Ways.

August 23, 2012 by Caleb Kraft 50 Comments

As I mentioned earlier, we’ve got an AR Drone to play with. One of the common mods that popped up on the internet were ways of extending the range on the AR Drone. It normally uses a local Wi-Fi connection to your phone or tablet for control and video signals. Many found this quite restrictive and have gone pretty far in extending that range.

The first and easiest was just to set up a higher power Wi-Fi Bridge where you’ll be flying. The Drone only has about 15db of wi-fi magic in it, so anything stronger than that is an improvement. There were too many variations on this to delve into the details, but as you see, there’s not much too it.
