Bot Paths The dynamic of the red robot

Don't read if you want to do level 7 and 14 with no help ! (it for that i post here)

I arrest in level 14 and remarks the dynamics of red robot is strange so i share my hypotheses.
I retry the level 7 and i arrived to this hypotheses :

*red robot do a walk-turn-walk if he have one block where he can walk around him
*red turn only if he don't move anywhere
*red robot can do left of map with no help on corner
*red robot can use downstair/upstair with no help (level 14 is exemple)
*red robot can use elevator and transport by drag block
the most important dynamic
*red robot do help for go right in corner, it need to block with you to continue (level 7 is exemple)

Perhaps i try element and situation different and continue hypotheses.

Edit: A good train for red robot : 19
