I don’t understand (nor find find the folder in which it is defined) the TrajByNameRequest srv variable.
I do understand how the TrajByName srv variable is created.
On < Unit 4: Services in ROS >, in the < Python Program {4.5}: simple_service_client.py >, the srv variable TrajByNameRequest is imported alongside the TrajByName srv variable.
Although, when I check the folder < /home/simulations/public_sim_ws/src/all/iri_wam/iri_wam_reproduce_trajectory/srv > , there is no TrajByNameRequest srv variable defined; only the TrajByName srv variable appears.
Thank you in advance.
