Cambridge Autonomous Underwater Vehicle

The Cambridge Autonomous Underwater Vehicle, built for the SAUC-E Challenge, is a fantastic example of UAV construction. The competition is to build a UAV that can complete an underwater assault course. This baby has a full computer inside it, based off of the worlds smallest full featured x86 motherboard, the Pico-Itx.  It has a 1GHz EPIA PX 1000 Board, 1 GB of RAM, Wireless Network capabilities and runs Ubuntu server 8.04.

The CUAV suffered from leaks which ultimately cost it the competition, but the information on the build is fantastic. They have detailed pages upon pages of information about the Mechanical, Electronic, and Software aspects of the design.  They even went back in and added notes from what they learned during the competition.  The project is also outlined in much shorter form on the mini-itx website.

“Killer Zombie Drone” Is Awesome And Recycled

Usually, when someone mentions military drones, we think of something much smaller and less intimidating than this monster. This is an Airforce Phantom II, retrofitted to be a computer controlled killing machine. Able to carry 18,000 pounds of stuff that goes boom, a single computer can control up to 6 of these in formation.

Sounds scary doesn’t it?  Actually, though these are capable of being offensive, they are mainly used for target practice. These are decommissioned units that have been fixed up and modified to be radio controlled.

ArduPilot Pro Autonomous Drone

We wrote about [Chris Anderson] before when he released the Arduino based autopilot. He has since crashed his first Predator UAV, due to an underpowered motor and poor control of the v-tail only steering. He has since released a pro version of the autopilot controller, and is modifying this UAV Predator drone kit to work with it. One ATMega168 processor handles flying and the other handles GPS navigation, but because they work together, it results in a fully autonomous drone. He also has a BlimpDuino version we have covered before.

UAV Medical Couriers

We’re skeptical about most technology that’s designed to help remote villages (yes, even that one), but these new UAV medical couriers look like a great idea. The turn around time for medical sample analysis in remote South African villages can be excruciating. A team of engineers have attempted to adapt two different unmanned aerial vehicles for transport of medical samples. These could be either blood or saliva that needs testing. Test results would be relayed via phone as they are now, but the initial transport time would be much faster. The larger of the two UAVs can carry up to 500g; that’s enough to haul two units of blood for transfusion. The UAVs can be launched by hand and can survive winds up to 45kph. They fly their preprogrammed routes autonomously and don’t require any operator intervention. The team has flown two successful trials and is waiting for approval from the South African Civil Aviation Authority. For safety, they’re only transporting samples that can be sterilized before flight. New Scientist has a short video after the break. Continue reading “UAV Medical Couriers”

Ardupilot: Arduino Based UAV Autopilot


A short while back, [Chris Anderson] released an Arduino based autopilot. It rings in fairly cheap and being open source, you can tweak away. To add more functionality, he’s releasing a dual core version. Thanks to the second processor, it no longer requires an external hardware co-pilot. It uses an on-board GPS and features an ATtiny based fail safe. It’s still under development, but he’s made the design files available.

IPhone Used To Control Squad Of UAVs

Building UAVs
is only half the work involved in making them fly; the other half is a control system. The Center for Collaborative Control of Unmanned Vehicles (C3UV) from the University of Califorina, Berkeley has devised a way to control a squad of RC airplanes with an iPhone. The system works by submitting commands and coordinates to a web site via the iPhone’s web browser. The site then sends the commands to the team of drones, which carry out the orders. The drones are outfitted with cameras and a tracking device, which allows them to be monitored on the ground using Google Maps.

The iPhone Terms of Service specifically prohibits it being used to drive remote vehicles, but that shouldn’t really pose a problem: since the orders are deployed via the iPhone’s web browser, they could technically be given by any web-enabled device. Before anyone cries foul, though, bear in mind that the idea is to issue orders from the field, and the iPhone is perhaps the most high-profile mobile web device on the market, which maximizes the project’s exposure. Still, we can’t help but think that they’d have gotten more media attention if they had used a hacked Kindle instead.

24C3 Build Your Own UAV


The 24th annual Chaos Communications Congress in Berlin is already off to a great start. The first talk we attended was [Antoine Drouin] and [Martin Müller] presenting Paparazzi – The Free Autopilot. Paparazzi is an open source hardware and software project for building autonomous unmanned aerial vehicles. The main hardware board has an ARM processor and GPS. It uses inertial and infrared sensors to determine orientation and altitude. The four infrared thermopiles measure the air temperature. The ground is warmer than the sky and if you compare the temperature in the direction of each wing tip your can tell what angle the airplane is at. It’s really that simple.

They did a pretty amazing live demo. Using the network connection they controlled a UAV flying in France and another in Germany. Both planes were streaming live video from belly mounted cameras. One relaying through a home DSL connection and the other through a UMTS cellphone. They were able to change way-points on the fly and issue flight pattern commands. There is a ground crew at each location with a security pilot that will switch the controls to manual if things get out of hand.
