Re: Running loco positioning problems
I have a basic idea where goes wrong with error i)
There isn't /crazyflie/base_link frame. So, there is error in RobotModel and Axes.
But I still didn't know how to create /crazyflie/base_link.

Re: Error flash crazyflie firmware with kalman config.mk
I saw there are topics to publish /cmd_vel and /goal. But I'm just worried about radio delays. If the cmd is transmitted from ground pc to drone, it requires a very robust tele channel.

Re: Error flash crazyflie firmware with kalman config.mk
thanks, this part should be no problem.
