Hi, I need some help. I have a problem that I want to input a pedestrian which follow the dataset. Which means I have a dataset that included the position(x,y), line velocity(v), angular velocity(w), and time step. Then, I need to add a human into gazebo follow the time step, and he will go to the next position in next time step. I did it in vrep before, wanna to realized it in gazebo. Can anyone help me or give me some suggestion? Thank you very much!
