Like I give command
group_command.control_strategy = ['Strategy4']
after setting the above in python script when I give velocity command in loop my actuator doesn't work. I guess there is something wrong with setting command strategy. kindly let me know about this.
This feature prevents unpredictable/harmful behavior in case a program crashes, and also serves as a "lock" that prevents an actuator to receive commands from other sources. You can find more information at https://docs.hebi.us/core_concepts.html#commands
Scope specifies a lifetime of zero, which means that a a command lasts indefinitely, but also does not lock the actuator.
Looking at the documentation here you'll find that the gains.xml file is structured to include a control strategy parameter for each of the actuators in your system. In this way, you don't need to programmatically set your control strategies in your code - it should get easily loaded as a part of the gains file for your system.
