Your goal is to program the robots to reach the home robot. To do this, you'll need to drag arrow tiles onto the grid to guide the robots. When you're ready to test your solution, click the "Run all tests" button and watch them go!

As you proceed with these tests, you'll have more robots and more tiles to use. Rainbow tiles will cause robots to "split"; you'll need to get all the robots home safely! Some maps will have holes that you don't want your robots to fall into. Eventually, you will encounter boxes: wooden boxes can be pushed, but steel boxes CAN NOT be pushed.

In the bottom left-corner of the screen, you can edit signals on the robots to make them perform certain actions when they're stuck or pushing moveable objects. There are two functions: on_cant_move() (which has the robot perform a certain action when they are unable to move) and on_can_push (which has the robot perform a certain action when pushing a box).

If a solution doesn't work, you can always rebuild your path! If you want to test how a robot will move on your path without them actually moving, select a test case and click "Run test" to see how it performs.
