Well, a quick look through Patrik's graph suggests me that the node CrazyFlieJoystickDriver is not publishing any transformations, and after diving a little into the file joy_driver_pid.py, I found that those transformations occur in function getErrorToGoal, which is called here inside the function...

Hi Oliver! We've got the tracking working fine but when we press the L1-button the flie just takes of like crazy. This is the graph i get from rosrun tf view_frames frames.pdf Any ideas of what might be the problem? Patrik Hi Patrik, glad tracking works now. What was the problem before? Did you hav...

Good luck

Check these lines of code:
Crazyflie log being forwarded to ros node
ros node sending log and tf stuff

Quick look at the code checks condition setPubToRos == True. Make sure the checkbox "publish to ROS" is checked in the settings tab.

It looks like cf0 is not being published at all. It appears on your frames.pdf because it is the parent of the statis transform publisher. Are you connect to the flie and logging roll, pitch, yaw at 100hz?

Is this the same as unchecking the "Disable Hover Mode" in the Input tab? Nope, this is just a hack for the moment. Usually my "hover button" served two funcitons: half press = deadman, so you need to keep it half pressed while flying. if you drop the controller or want to cut p...

Thanks for the reply, Is there a way to get the acceleration in cartesian coordinates in your code? I've tried to look at your code and the closest I found was the "self.acc" but I'm not sure if this is the right variable. I need it for the kalman filter :D I guess you could use the roll,...

Hi guys, sorry for the slow reply. Im looking for a way to implement an Kalmanfilter to your code omwdunkley. Is it possible to just add a method in your trackManager.py or do you have to create a node to do this? Good question, I guess there are multiple points of entry. I am not sure which is best...

Ah, VMs were in the play :) Yup, so next up is makeing sure the transform tree is set up as expected, running the pid controller node, running the custom cfclient, detecting the background (uses depth registered depth images, dont use the pointcloud at all) and then detecting the flie :) Lemme know ...

Good to know, thanks! Two years ago ~ That's before crazyflie. Were you working with AR Drone? Yeah, the ArDrone 1.0, not the current one :) The ardrone has two huge advantages over the flie that make it "relatively easy" to start programming with: Ultrasonic altitude measurement - so you...

Hi!
I took the class room version of that course two years ago and strongly recommend it I learnt a lot, the presentation materials and tasks were top notch. It even won some top lecture award that year.

Enjoy it!
