"Just for future reference, we figured this out by using the following:
To convert the NavEKF Euler angle to quaternions:
To send the quaternion message in MAVLink:
"Ok, after some searching, it seems that ArduPlane doesn't send message ID 31. Anyone know where I could grab quaternion values from the controller? NavEKF::getQuaternion() doesn't work. I want to send a mavlink message…"
"@Austin: Great to hear from another team! Yeah, I've been able to land my personal UAV for a year on auto-landing, it's just a little nerve racking to try and land the competition plane under PixHawk control. We've come in for approaches under full…"
Hey guys,I'm working with the newest ArduPlane, and I'm trying to get the following messages at 10Hz from the PixHawk over the second serial port to another microcontrollerMsg ID: 31, Name: ATTITUDE_QUATERNIONMsg ID: 33, Name: GLOBAL_POSITION_INTMsg…
"@Justice: We can't do IR landing, we may or may not have access to the landing area before landing. Other than that, IR landing looks awesome and we might work to implement it in ArduPlane this summer anyways :). "
"@Justice: We haven't looked into IR landings, but I'll look into it now.
@Bil: We're using a pneumatic catapult that fires at 90psi. Custom built.
@Antonie: We have thought about using a ballistic parachute, and we might use one next year. This…"
Hey everyone,I just wanted to give a little background on our team, CUAir, Cornell’s Autonomous Aerial Vehicle team. We compete in the AUVSI SUAS competition (more information here). We’re a group of 50 interdisciplinary students working on…
Hey everyone,Just to introduce ourselves, we're CUAir, Cornell's Autonomous Aerial Vehicle team. We've been working with the ArduPilot for the year, switching over from a commericial autopilot. Most of our work is going into designing a new web…
