title: How I can add a trained RL controlled vehicle to the system in tutorial01?
body: <p>I would like to know how I can add a trained RL controlled vehicle in the system in the tutorial01.</p>
  
  <p>I have run the tutorial04_rllab. I added an RL controlled vehicle with the name “r1” and successfully trained it.  Now, when I want to do the same in tutorial01 I cannot. It seems that this RL controlled vehicle cannot perform well.  </p>
  
  <p>Could it be because I didn't add the trained RL controlled vehicle?</p>
