Good way to make a quad blade guard?

So I was reading the article on the MIT guys using the kinect to map out a physical space and what struck me was not the amazing mapping technology, but their really great guard they've got on their quad props.


It looks like the straight edges are CF Rods... does…

Flying 'thing'

Hi all, its wonderful to see wonderful creations... I've been envious (not jealous :) ) of many a post now, and decided to get even! Unfortunately here (Nairobi, Kenya) the electronics are limiting, no access to good airframes save from importing, leaving us enthusiasts disappointed, so I have decided to start with an airframe, then build the logic to fly it using a small…

ArduPilot - First Flight

Ok, I've spent the last few weeks putting together my ArduPilot and plane.  It's running ArduPilot 2.7.1 in "Stabilize" mode.  The first flight was not very stable, possibly due to the fair amount of wind, but also because the ArduPilot is not tuned.  I've read the manual and have some observations/questions for anyone who can answer.
1. I'm running on a plane, Sky Fly Max by Hobbico, that is a boom type plane with ailerons, rudder, and elevator. I've modified…

Easy Star Bathtub mod :-)

Here is my quick mod to make it easier to fill up my Easy Star with all the gear. The lid will be held in place with 6 pair of magnets glued to the fuselage. I did the prototype with 3 mm balsa but the next version will be in 2 mm ply. I will probably make a box on…

Remember that RC Fullsize mid air last year? FAA report out

They seem to point the finger at the RC pilot, although I think both pilots were showboating. That is unless smoke on and stay down is a standard go around in the USA

Choosing a 3D Package

Having recently developed an interest in CAD and modelling (i.e. industrial design tools not standing around in a bikini). I found this handy video on CadJunkie that runs over some of the different approaches some of the different packages take (Subdivision, NURBS surfacing and solid modelling). Looking at some of the awesome CAD renders on here i'm sure many members are already quite familiar with this, but for anyone who like me hasn't really touched CAD since the…

Visual Odometry For GPS-Denied Flight with a Kinect

The Robust Robotics Group at MIT has developed a system that allows a quadrotor outfitted with a kinect sensor to fly autonomously in GPS-Denied environments, building a map of the environment.

Unlike previous work, our system does NOT rely on external motion capture to localize and control the vehicle. All sensing and computation required for local position control is done onboard the vehicle.

We have collaborated with members of the Robotics and State Estimation Lab at… Continue

Arducopter with 8 Motors - Crash, Rebuild and First Flights

Here is video of first flights with the new lighter Hashcopter. PIDs make it a bit agressive and unstable because of reduced weight. Also you can see the massive camera flying with the copter.

Story goes like this:

I had a bad crash after few hours of flight time with Hashcopter. Crash was caused by flying the battery too empty and one off the ESCs cutting power off. The copter is capable of landing with 7 motors but I made a mistake flying to…

Software development, 150 seconds at a time

Decided to fly with the photodiode azimuth sensing & it was a disaster, as expected. It reminds us of the years spent on Heroine 2200's photodiodes, trying to figure out a way to intelligently detect the start of a period.

Detecting the period was hard.  Fast fourier transform needed much more cycles than our flight time.

The best result was by testing…

Seaplane UAV concept

It is only a design exercise with a wingspan of 1640mm, and a lot of space for electronics and batteries and very easy access to electronics. Last image shows 6 x 5000mAh/3S.
