UAV Flight from Vieques to Puerto Rico!

Hello Everyone,

I am an aerospace engineering Ph.d student at a university in New York and also the teaching assistant for an undergraduate course in aircraft design which will be partly taught in Puerto Rico. One of the main objectives for the course is that the studens have to design, document, and build radio control airplanes following traditional design formulae. Having following this community for a while, I proposed to the course instructor and also my advisor to attempt to fly autonomously at least one of the student designed airplanes off the coast of Puerto Rico from the island of Vieques to mainland Puerto Rico which is close to 20 miles!! I have been given the approval and my plan is to use the Ardupilot with pre-programmed GPS way points to accomplish this at least semi-autonomously. The idea is to also establish visual contact during the entire flight using a chase boat. I would like to ask the community, whomever has successfully implemented and flown the Ardupilot system including wireless telemetry with the ardustation or otherwise, if you would be interested in being a consultant to the project. If so, leave me a comment with your contact information and I will get back to you with further details. We plan to fly the RC airplanes/ UAVs during the first week of June in Puerto Rico of course, just to give you a time frame. Thanks everyone, Victor.

Hello everyone, I've been visiting the website for a while and have enjoyed reading the discussions here, but this is my first official post. I am working on hovering my co-axial helicopter and decided to do this using the Propeller chip, and specifically using the Sparkfun 5 DOF IMU and Jason Wood's code which we all appreciate. To make a long story short, I downloaded the code successfully to the development board with the IMU and ADC soldered according to the circuit in the code, but I am having trouble checking whether the IMU gives me correct angle, rate, and q bias. I am using the modified FullDuplexSerial object to display the readings from the KF on the screen using the serial terminal, but I am getting various different errors. Is this the correct way to do this? I was wondering if someone who has done this before could offer any advice or procedure to check whether the IMU and Kalman Filter work. Any help will be greatly appreciated! I look forward to advancing my knowledge to keep up with you guys! -Victor
