Hi @byeongkyu,
This is very fascinating topic and I will write here how I am solving this issues with my customers.
I wanted to explain you this today, but I will probably not manage it. I will try to make a full description, a figure and few PR which could help you over the weekend.
Stay tuned!
Hi @byeongkyu,
sorry for taking me so long time. Here the explanation "how I would solve this":
LifecycleNode
on_configure
callback.ForwardCommandController
to trigger this. (We will have soon GPIOController which will be more suitable for this. You can find very complicated, initial implementation of it in UR driver repository).Please also consider following figure to better understand callback and lifecycle of the hardware in ros2_control
Many robots has multiple joints. Some joints needs initializing procedure for example, find origin point. Now, the hardware_interface has only init->read->write loop and it it not accept any commands by external.
How can I implement the jobs that said above?
