time_to_reach_goal metric relies on human agents data rather than robot's

Hi there,

I am using your package to test my navigation algorithm. To become familiar with the metrics recording, I started by computing metrics that don't involve human agents, such as time_to_reach_goal. However, in hunav_metrics.py i see that t1 and t2 are computed using agents rather than robot data. I understand that you use the header.stamp information to compute elapsed time, yet I find it a bit misleading.

Thanks for your time.

Hi!
It does not matter. The input of the functions to compute the metrics are two vectors. One for the agents data, another for the robot data along the trajectory. These vectors have the same length and the same timestamps for each time step along the trajectory. Therefore, the time elapsed is the same if you calculate it with the robot data or the agents data.
