Detailed Description
This system applies a thrust force to models with RCS-like thrusters. See tutorials/spacecraft_thrusters.md for a tutorial usage. Below follow the minimum necessary parameters needed by the plugin:
- Parameters
-
link_name Name of the link that the thruster is attached to. actuator_number Index of the element to be used from the actuators message for a joint. duty_cycle_frequency Frequency of the duty cycle signal in Hz. max_thrust Maximum thrust force in Newtons, applied on the «on» phase of the duty cycle. topic Name of the topic where the commanded normalized thrust is published. Unit is <0, 1>, corresponding to the percentage of the duty cycle that the thruster is on. Default uses the models name. sub_topic [optional] Name of the sub_topic to listen to actuator message on.
This plugin replicates the PWM thruster behavior in: Nakka, Yashwanth Kumar, et al.
