Want to record a trajectory and then play it back

Post by frossi » Mon Feb 11, 2019 9:19 pm

Hi,

I am part of a team that has recently acquired a swarm bundle.

We want to record a given trajectory by moving the CF manually and then play it back by sending those same coordinates to the CF.

I believe there was a post describing how to move the CF manually in order to record the trajectory but could not find it. Is it possible to do this and how exactly?

Thanks and congrats for an amazing product!

Fede R.-

This is correct, the icra demo was implementing this functionality. The file that has the implementation is there: https://github.com/bitcraze/crazyflie-f ... /retrace.c.

As a side note, this code should work with any positioning system, we had it working without modification in a Qualisys mocap: https://www.youtube.com/watch?v=3lDvWlbDSOA.
