Drones have the potential to perform many useful tasks, such as search and rescue, package delivery and aerial imaging. But in order to perform these tasks in an outdoor environment, the vehicles need to be able to control their position under the influence of wind gusts. This is especially true when flying…
The rotor diameter is 93 cm (36.6 in) and will operate at 1,410 rpm generating 2,000 g's of acceleration at the rotor tip, and developing 1,600 Lbs of tension in the flexelem rod due to centrifugal force. The blade…Continue
Here's a video from one of our recent tests of our GTQ-Cormorant: a submarine and quadrotor hybrid.
We use an air pump/solenoid system to move air between the clear, water-tight pressure hull and an external air bladder for depth…Continue

Every drone is uses a GPS ranging from position hold to way point navigation. But the performance of current GPS system has massive scope of improvement. Imagine a drone which can hold its position so well that its performance is comparable to a motion capture system's position hold and likewise for the way point navigation.
I have implemented a monocular visual odometry on Nvidia's JetsonTK1. Using this implementation, GPS can be replaced with this camera…Continue

This is yet another version of a 3D printed quadrotor, pointed to be one of the workhorses of my research... The main characteristic of this frame is that instead of using nut and bolts to join the arms and the base together, like in TEGO v2, I'm…Continue
I have a long history of being involved with R/C planes and helicopters and moving into drones is a natural extension of that. However, until recently I had little exposure to quad copters and I had the opportunity to see them fly at a drone meet. I got interested in them and decided to build my own…Continue
Hi, drone developers. I am a master student at department of Aeronautics and Astronautics, University of…Continue
NavStik users are now using NavStik to build a variety of autonomous systems. Its extremely small size and light weight (4 grams), coupled with a powerful Cortex M4…Continue
I'm very grateful to be in community that supports a laser-equipped Fab Lab. Lately I've been designing and fabricating custom components for my unmanned aircraft, especially components that are easily integrated into existing systems.
Above is a photo of one of my latest creations: a solution that houses a five or six-cell LiPo, an APM 2.5 autopilot…Continue

Conventional quadrotors are what’s called underactuated robots, which means that they can move in more ways than they have independent control over. For example, they can happily yaw around to any angle you want while otherwise stationary, but if you ask them to pitch or roll, they can’t do it without also changing their position: if you…Continue
First I would like to thanks to all the people that commented, see, and shared my work. I'm really happy you enjoyed it.
Now the important part. I've been very busy on the firmware and the flight software. The board is still the same :D. T he system is doing very well and the attitude autopilot is working great. Here is a video of the last…Continue

In this video the application of a Visual-Inertial (Camera & IMU) localization algorithm on a Parrot AR.DRONE quadrotor, for enabling real-time GPS-denied autonomous navigation, is presented.
A sensor package for data logging, consisting of a Beaglebone computer, an…Continue

I completed my first build recently, having made a quadrotor. I built it from scratch, no kits involved, using Wii bits for the IMU and a LPC2103 for the brains running my own code. Weighing in at around 2.4kg it's not the lightest quadrotor around, but its motors are more than powerful enough. I've yet to…Continue

Finally my x550 and APM2 quadcopter is complete! And I have successfully flown!.
Right now I seem to have a bit of yaw problem, as well as a trim/balance issue. Since the frame is not quite flat it can be hard to tell exactly what should be level, and when I yaw in a different direction, it seems to always return to original. I think I need to…Continue
