Hello,

Is there a ros2 package that supports publishing the pose of the tag detected by voxl-tag-detector?
On https://docs.modalai.com/voxl-tag-detector/, I see there a description of using voxl_mpa_to_ros, is there similar support for voxl_mpa_to_ros2, so the detected pose is exposed as a ros2 topic?

Thank you!

@Alex-Kushleyev Thank you, appreciate the detailed response! (I completely missed this message, I thought I'd get a notification but I forgot to subscribe to notifications)

Hello,

We're using the voxl2 for our quadrotor and had a few questions related to how the px4 and escs are integrated to help us correctly tune our system's parameters. If you could help us out that would be appreciated!

1. How is the output (PWM value or motor control signal) of the thrust model (equation that uses THR_MDL_FAC ) used by the px4? Given a desired relative throttle value, does it calculate the relative PWM through the equation and directly send those to the esc? Or is the output of the equation used as a relative RPM, which is then sent to the esc as a rpm setpoint?
2. Our motors run fine even though we don't have the kv value specified in our esc parameters file. Would you recommend using the kv values?
3. The min_pwm and max_pwm specified in the esc file seem to scale from 0-999 while the pwms used to find the THR_MDL_FAC value in this script has pwm in us. Could you clarify the pwm units in the esc file and how it relates to those used to calculate THR_MDL_FAC value?

Thanks!

Adding more information (I work with Jeffrey), we get an error

[ Error writing lock file /sys/devices/system/cpu/cpu0/cpufreq/.scaling_governor.swp: Permission denied ]

I can't seem to delete the .swp file either.

Thanks!
