endrew posted a discussionNoisy gyro reading.
I am using invensense gyros with an ardupilot mega for a quadrotor imu/controller.Attached are the reading from my gyros which seem to be very noisy, perhaps from vibrations. Is this amount of noise seem normal to you? I think it's much to noisy and i tried many different ways to isolate the gyros from vibrations with no real success... See More

could you explain this issue NewSoftSerial about?

W. Thielicke commented on endrew's blog post Another quadrotor project"At the moment, the copter has to be more or less perpendicular to the cam and inside the FOV of the camera. If the camera is tilted +- 20° the calculations should still work I think, because nothing really changes, except that the markers get a…"
ionut commented on endrew's blog post Another quadrotor project"Hi W.Thielicke
Very nice.Does it work with the camera angled?Or the copter must be perpendicular to the camera?
Also did you try to switch position, camera on the copter and leds on the ground?"
W. Thielicke commented on endrew's blog post Another quadrotor project"Hi, looks very interesting! As MarcS already pointed out, something similar (but a bit less precise) can be done using a standard webcam + Matlab. 3D Position (x,y,z, yaw) and accelerations + velocities in all directions can be calculated pretty…"
MarcS commented on endrew's blog post Another quadrotor project"Hi Inout,
the clarontech looks as if it is designed for small tracking volume (medical). Interesting, anyway.
I´m well aware of the geometry and the necessary calculations regarding point tracking in 3D. You would probably use more then 2…"
ionut commented on endrew's blog post Another quadrotor project"MarcS I think you can use Wiimote with your pc but you need 2 wiimotes.You need to attach 3-4 leds to your aircraft and track them.You will have to calibrate your system.That means you have to know the position of the leds on your geometrical model…"

Remarkable stability.
can you to give the material that you took and the code.
Some photographs of readier of the model
Thank you
DODY"
MarcS commented on endrew's blog post Another quadrotor project"I like the tracking system. But so pricy...
Is there anything open source regarding indoor tracking?
I would first think of the sensors (camera) used in the Wiimote. If you could use custom sensors like these, a system should be quite cheap.
Thanks…"
Earl commented on endrew's blog post Another quadrotor project"Impressive stability !
Post details on hardware and post the code ??

Patrice Mainville commented on endrew's blog post Another quadrotor project"wow, impressive stability, what is the Optitrack system you talk about, do you have a link?"
Leon commented on endrew's blog post Another quadrotor project"That's exactly what I am trying to do, but without the optitrack system. My indoor drone only uses 4 sonars + 1 IMU.
Obviously, I will not reach the same performance."
endrew commented on endrew's blog post Another quadrotor project"This clip is shot in Ben Gurion University in Israel, In one of the Mechanical Engeneering labs.
I've been playing around with quadrotors for a while, and when I discovered the optitrack system, I had to see if It will work... :)"

Its based on Arduimu - flat version.
Everything works at 50hz.
I used SPI to communicate between the CPUs.
Stabilization is simple gyros(drift corrected) feedback loop.…

Season Two of the Trust Time Trial (T3) Contest has now begun. The third round was a reliablilty/aerial photography round for both planes and copters, which is now closed. Stay tuned for the next round, beginning soon.A list of all T3 contests is here.
