  Moved to graveyard:
Cooked :/

  Yep, I was worried that would happen. Bot 1 gets two spaces away from the bot which is used as a marker.

I can see a way to check for that, but it woud involve lots more remotes - but it might make the entire bot mechanism (which I like) to be pointless. I'll keep thinking about it, and set this one aside in the graveyard for now.

  11 steps is supposed to be the maximum with only the values 1, 0, an -1 for the total as acceptable. Extending to +/-2 allows over 1000 steps (apparently) which is probably too large to implement. I'll check your solution now, and if it is okay then I'll let you know.

  OK, got it now. How far can the sequence be extended?

  Added speedrun: 40 moves (old: 41).
One of a number of similar solutions that probably shouldn't work. Didn't fully understand the original though, so I can't be of much assistance.

  'Disintegratable Instructions' uploaded by N7DOT:
Write a set of 11 instructions to apply to a value (which starts at 0) (either add 1 or subtract 1) such that if followed in order, the total will never be 2 or -2. But the twist is that the instructions must STILL work if only every nth instruction is followed.

Not that hard, but I had a hard time devising a way to ensure that a valid path was taken (I'm worried it may not work, though).
