Re: [Autopilot] Hello!

Hello Spencer,
Helicopters also captured my interest several years ago. I have built an
AHRS and GPS+AHRS unit for the start, based on cheap atmel avr overclocked
chips, implementing two Kalman filters (attitude for fast loops and hovering
position) and excited integer ahrs matrix lib published on this site. I used
some kind of fuzzy logic and several cross-linked pid&pd loops to hover
electric powered zoom400 small helicopter. The power of integers was not
enough to hover bigger concept 60 helicopter and the next step was intel
PXA255 board, Xemics DP1203 and some avr based custom pcbs. I would like to
tell about this subj, that I have tried to implement ideas of hovering
published in "autopilot" source, but i still had to do a lot of work in case
of bigger helicopters, and at the end to develop my own algorythms for
hovering which were very exciting when i have seen some human pilots and my
robot hovering at the same time and circumstances, and robot was just the
perfect in the winds up to 5m/s. 
I would be glad to share some experience. I am working on
gumstix+xsens+maxstream+avr. My goal is to create cheap and effective
hovering autopilot for helicopter UAVs of 3m hauptrotor.

Subject: [Autopilot] Hello!



Hello all:

 

I stumbled across this site doing some research, and got really excited
about what I saw!  

 

Some personal info:  I am an aerospace engineering major, new to RC
helicopters, but they have captured my interest.  I build research UAV's for
a living for my university, and love my work!!!

 

I am interested mostly in the implementation and testing side of things,
applying the knowledge to the field.  My goal is to be able to use this
system both as a supplemental control system and maybe even use it instead
of the more expensive options out there.

 

One question I had for the group was: what hardware do I need?  I looked on
Rotomotion's site, but there seemed to be a couple different options, so if
anyone can answer that for me, that would be awesome!!!

 

Thanks!!!
