Franken-Bots Movement sequences of a headless R Bot

On the 3-10-4 level I have pointed out a surprising and sequential behavior of a headless R Bot (which means the body alone without eye or anything else).



It doesn't seems to be a new discovery but no investigation has been made before, so several creators though as an erratic behavior of R Bot (a crazy bot ). Strange as computers and programs follow a logic pattern...

Recently @Scare Crow used it in his Patience level. So maybe it's time to dig deeper on the subject and try to find out what's going on behind this.

When we let a headless R Bot walk on his way we could thought of a crazy bot with unexpected rotations behaviors. In fact he follows this pattern:


So R Bot follows a sequence of 3 steps, turn right, 10 steps, turn right, 4 steps, turn right then starts over from the 3 steps sequence.

First conclusion: it doesn't seem to be a bug but an algorithmic behavior. For a reason that I ignore @Martin Magni coded the movement of a headless R Bot like that...

Now... Another question pointed out : what happens if R Bot is stopped in his path? That's were I am stucked... It seems that he doesn't follow a logic path until the moment is coming back to the 3-10-4 sequence.

Here is a testing level I have made. It is intended to test the behavior of R on the 10 steps path initialy but the 3 and 4 steps sequence can be checked too. The red bricks are the place where R turns depending on the step you stop him (for step 3 and 8, the next should be 10 but the world is to large to place them...).


It's hard for me to beleave that an "if...then...else" code condition decide for the movement of R Bot when an unexpected obstacle is on his way, but until now I don't have more clues and it could be great to find a kind of "single equation" on that. I could share some others partial results but I know some have interesting stuffes to post

For now @Scare Crow (and now @meko it seems ) try to investigate on that but maybe more want to join the party

Let's share our testing levels, results, questions or fulgurances together!

 

You're right, when R Bot is in front of an obstacle he leaves the 3-10-4 sequence for a while but he comes back to it after an unexpected sequence. So he didn't forget it. On your testing level R is walking 2 steps before the obstacle then 13 other steps (unexpected) before coming back to the "magic" sequence. If blocked after 1 step the unexpected step would be different but not the final goal to the magic sequence. I wonder what is the logic behind this unexpected sequence...
