I am studying Mechatronic Engineering at Chico State, and work at Tesla Motors in Fremont.
Please tell us a bit about your UAV interest
There is something awesome about giving an inanimate object autonomy...

It seemed to me when I originally joined this site it was way more about hacking/programming/tinkering and dedicated to trying to solve the "drone problem."Now it seems like more of a market place and site to discuss ready made products.But maybe…
Hello All! I am working on a project where I have two devices that constantly trying to locate eachother using GPS modules and LoRa transcievers. Its a buddy tracker for spearfishermen, to make it easier to locate your partner when you're out in…
"Hey guys, it has been a while since I worked on this. I am glad other people are looking at it. I struggled for a long time with magnetometers, and really could not find any decent explanation on why the rotation matrix is constructed this way.

"I was under the impression that most off the shelf GPS units do not work at this altitude, but obviously this is not the case. Do companies (like ublox) put any firmware restrictions so they do not operate at certain altitudes/velocties???"
"Hmm, my tilt-compensation looks exactly the same:
//My Math: Rotation Matrix from body frame to vehicle 1 frame magComp[0] = (magVector[0]*cosPitch) + (magVector[1]*sinRoll*sinPitch) + (magVector[2]*sinPitch*cosRoll); magComp[1] =…"

"Are you programming your own IMU?Make sure your sensors axes are all inline. For example, I am using an MPU-9150 which consists of two sensors.
So in my case, I switch the x and y values of the magnetometer, and switch the sign on the z-axis.…"

Hello All!I have searched far and wide for a good tilt-compensation algorithm, and a decent tutorial to accompany it. I have read application notes and looked at lots of source code, but I never really understood where it was coming from, and none…
"Do you have a picture of the vehicle?
I guess the simplest thing to do would be to drive the vehicle around for a bit collecting magnetometer data...
Or would that not give you the data you need?"

"I am not familiar with their transmitter...I haven't even used ArduPilot extensively (I've been playing around trying to build my own platform), but I still have received lots of help from nice people here.

"I think you should give hobbyists more credit, I would guess that a hefty percentage of those people going on to kickstarter to back a project like this are already involved in RC in some form."
"Hello!My name is Brett Smith, and I saw that you were trying to back the Thalumus project on kickstarter. I have been putting together an open source AHRS for one of the engineering clubs, using an 8-bit AVR instead of a full ARM cortex. I am trying…"

Hello All,I have been working on an propeller based autopilot for a while now, and things have been coming along great. Although I was nervous about the lack of interrupts, the faster speed and multiple cogs have made timing the program efficient. I…
"Start building up your code! I would start testing your electronics on a breadboard.
Make sure you can provide all sensor data to the arduino mini pro. Make sure you can use your arduino to arm all ESCs and to control the speed of all four motors.…"
