No. If you want guaranteed 1kHz control you need a realtime kernel. The lower limit on Rate/Timer are dependent entirely on your system and load level.
Hello-
I'm writing a node that will be my servo loop for a robot. In a previous implementation the timing consisted of checking the system microsecond counter and calling the servo update each millisecond.
Can I use ros::Rate or ros::Timer to get anywhere near 1 kHz rate? If not, what is the practical lower limit for these?
Thanks,
