[Ricochet Robots] A puzzle a day keeps the robot doctor away

Ah_Pook

Hey I hear you like solving spatial puzzles!

Rules: You need to move the selected robot to the selected target, which is determined by the goal token in the center of the board (color and symbol). Robots move in a straight line horizontally or vertically until they hit something (a wall or another robot). Each such move counts as one move. The goal is to move the selected robot to its' goal in the fewest possible moves. The robots are randomly placed at the beginning of the game. The end position for the robots after getting the target robot to the goal is the start position for the next puzzle.

The actual game has a time element to it which is not going to be replicated here. I'm going to check for answers each afternoon(ish), and whoever has posted a correct answer that is the fewest moves will get a point. There are 17 goal tokens, so we'll just go through them all and whoever has the most points at the end wins. Feel free to drop in or out as we go. Points will be awarded and new puzzles posted sometime in the afternoon EST each day.

You only get one answer submission, and we're going to use the honor system here that no one is going to look at other people's answers before submitting. Post answers in the thread in this format please:

Is the next rounds new starting states based on the individual's previous end state or based on the best route winners state?

Ah_Pook

I'll start the next one from the end state of the first winning solution posted

Blue down, goal.

discrider

So... if the end state is the next start state..
We should aim for non-target robots to end on the outside of the maze for bonus points right?

(Read: to make them as useless as possible)

Ah_Pook

It's hard to know what will be useful since the goal token is random yknow.

Vyolynce

For the first several rounds, anyway.

Ah_Pook

Please put the number of moves the spoiler as well, so no one gets any hints before they submit their answer

discrider

Yeah, looks ok @Elvenshae , but you should spoil your move count

Jam Warrior

Nice to see an alternative at the same move count.

Ah_Pook

Puzzle 2 up, points given. Bunch of people got 8, Elvenshae gets cool points for getting 8 in a different way than everyone else. I get cool points for posting the worst answer, with 12

Now I can read your answer, I really can’t see one less being physically possible, but I’d love to be corrected.

Hey Pook is it possible to put the new puzzle in a normal post as well as the OP? Having to scroll all the way up is going to get tiring.

Jeeezus.

Found a few 7s involving moving multiple bots, checked Vyolynce’s answer so I could use a different one to his, and see he has a much simpler better answer.

It’s so obvious with hindsight!
