Clarence Hanson replied to Clarence Hanson's discussion USB connected RC transmitter"No, no trainer or remote is in this loop. It is something to connect to your computer then the computer produces the signals being sent to the RC receiver. The idea is to set the commands for each channel of the RC vehicle on the computer. Right now…"

Hello everyone. I have not been on the site in some time, and the question I am about to ask pertains to a post I know I read on here about a year ago, but have been unable to locate it. I am looking for a piece of hardware mentioned in a post from a while ago. The peice of hardware is a USB connected RC transmitter. The idea is to be able to transmit PWM signals of the type used to control RC vehicles, generated by a computer program. So this piece of hardware is not a remote control, but…See More
Clarence Hanson replied to Clarence Hanson's discussion Auto Trimmer"Alternatively the readings could be recorded from 2 seconds in the past, so in order to trim you need to have the AC is the desired state for over 2 seconds without needing to move the controls, then you can release the controls while switching to…"

"Not a bad idea, but users would have to be sure to have their hands off the stick when switching to auto...."

Been a long time away from the website, and I gotta say you guys and gals have made some significant improvements to an already impressive system. I hope to be back in the field playing with our UATs this summer. I have a question/suggestion, and it involves an auto trimming function. After briefly looking over the code and reading a manual, it appears that the trim values need to be recoded each attempt, even though you keep the values used for the controls in RAM, meaning updating it should…See More
Clarence Hanson commented on Clarence Hanson's blog post Our very first flight (with two way telemetry)"Been a long time guys!
Unfortunately, with the semester starting up and it being too cold to fly comfortably in Michigan (we go to an Air Force base so its a process to get flying) we have put the project on hold.
I would be more than happy,…"

"Clarence
This is pretty good work. I am mainly interested in two way comms between GCS and plane. Have you implemented any form of sense and avoid ? How does each plane avoid each other in air when multiple planes are being controlled from single…"
Roger A commented on Clarence Hanson's blog post Our very first flight (with two way telemetry)"Any chance of providing the amended source code for the ArduPilot and documentation on the changes made to support two way communications?"
Clarence Hanson replied to Diarmuid Wrenne's discussion Multiple Serial Devices"We use a software line with success. The soft serial library contained with the Arduino IDE is severely lacking, but Mikal Harts Soft Serial library (http://arduiniana.org/) is much more functional (although it shares a timer used to control servos,…"
Clarence Hanson replied to Diarmuid Wrenne's discussion Software Serial for GPS"I forgot to mention. When we use the software serial line to communicate we do get jitters in our servos. I imagine this is because the timers normally used for holding the servos are being "borrowed" to operate the software line, but I am…"
Diarmuid Wrenne commented on Clarence Hanson's blog post Our very first flight (with two way telemetry)"Very nice work. I think a project to build an open source ground station similar to the paparazzi one would be nice. Any move on trying to fly the aircraft via a serial uplink. I wonder whether a process that basically updates the target way point…"
Clarence Hanson commented on Tj Bordelon's blog post Finally, my autopilot is "finished"...."That is so cool!"
Clarence Hanson replied to Diarmuid Wrenne's discussion Software Serial for GPS"We use a soft serial line to communicate through an Xbee (our GPS talks at 1 Hz and our groundstation talks to our AC at around 12 Hz, so it should work) to our GS. The SoftSerial that comes with the Arduino IDE is severely lacking in functionality…"

A couple of people at the University I attend and I had our first flight the other day, and we wanted to tell all of you about it.
I will start with the goals of our "team". Our goal is to create a network of UAVs that allow for mulitple users and/or multiple ground stations attempting to control multiple vehicles. We felt that the ArduPilot platform was perfect because we have access to source code, it is inexpensive and a vibrant community which could, hopefully, provide… Continue
