I like the idea a decent amount.
I've played a game before where you need to preload your actions before executing N-turns, but it was a medieval combat thing so it didn't make much sense.
Pre-programming a rover makes a lot more sense for this mechanic.
I think it would be easier to both develop and play if the map used a grid system.
Picking directions to move and spots to investigate are tricky if you have to pre-plan everything.
It would be easier to remove the angles, just have cardinal movement, and just investigate whatever space you happen to be on at the time.
I'm also curious to see how you make all those unimplemented interruptions feel fair or... preventable? Solvable?
With a system like this, I find it easy to imagine that the plans are so fragile that any interruption at any point just tanks the whole thing.
