With full commercial integration of UAS on the horizon for 2015, open-source projects like ours have the potential to erradicate barriers to entry into the UAS marketplace.
The regulations involved with getting software certified by the FAA are pretty
Read more…Sorry for not RTFM'ing this, but I actually have an urgent need for a piece of info that I can't seem to find. I demo my fuzzy controller to one of my professors in an hour, and I haven't figured out how to make the GCS do what I need it to do.
All I
Read more…Hi guys,
I'm kind of a noob with RC helis in general, so I'm making some noob mistakes and breaking stuff that I probably shouldn't be having a problem with.
Today, I was doing some flying on my TREX 450 Pro V2 3GX, and the heli flew great. But when I
Read more…I'm moving from my flybarless TREX 45 to a Raptor 90 SE with a flybar soon.
I heard that control for roll and pitch is rate based, and we have full acro control, but does stabilize mode also work?
Also, are there any general rules to consider when set
Read more…Here's a tutorial on exactly what PID control does for this type of system. I know I'm probably preaching to the choir for most of this, but for anyone that's never had any formal training on control systems, maybe this will help put things together.
Read more…Hey guys,
Not sure if anyone remembers, but Craig and I were working on the fuzzy logic attitude controller. That project's going nicely, and we've got it controlling pitch and roll in the HIL simulation environment.
But we've run into a pretty big SN
Read more…Hey guys,
I've got my T-Rex 450 all set up. I loaded the stock software with the stock PID values. It held stable fairly well, but I got no rudder when I moved the stick.
Then, I changed the P values for rate and stabilize on the rudder. I got a move
Read more…I decided to go with the TREX 450 Pro V2 3GX because it comes out of the box without a flybar.
At the same time, the 3GX module that comes with it creates questions.
Is the ArduPilot already designed to perform all of the functions that the 3GX does
Read more…I've been flying in HiL, and it doesn't look like the code is doing anything to maintain a target altitude while navigating on auto. I also can't put in my own stick inputs to correct it manually.
Does this happen in real world application as well? I

Allow me to introduce myself.
I'm Chris. I'm an electrical engineering student at the University of Texas at San Antonio, focussing in embedded controls. I'm currently the chairman of our IEEE student chapter robotics team.
I'm new to open
Read more…I posted something on this in the trad heli forum, but there's been no feedback, and the user group forum seems to get more views, so I'll mention it here.
Recently, my robotics team has been playing with some pressure sensitive resistors, and it got

I've noticed that ground interaction has been known to be troublesome automated takeoffs and landings.

Allow myself to introduce.. myself..
I'm Chris. I work in a controls research lab at UT San Antonio as an undergrad researcher. I'm currently doing research to apply fuzzy logic as a replacement for PID feedback control in complex syst
