Overview

As you enter the puzzle, you see a blue emitter on the left, a room blocked by a blue door in front of you with a blue receiver next to it, and a room to the right past a purple barrier. In the right room is an inverter, and a red receiver that deactivates a blue door to a third room with a rail drone and a connector in it. Behind the blue door in the first room is another empty room with a red receiver, which controls access to the progress wheel.

Hints

A basic hint:

[ hint ]

Since the name of the puzzle is Automatic doors, you have to figure out a way to keep opening the doors automatically

If you're having trouble getting started:

[ hint ]

After you get access to the third room, don't be hasty. Pick up the connector and connect it to things visible from that room so that you can move around while that connection is still active

If you're thinking about the rules of which laser color wins:

[ hint ]

A connector that is connected directly to an emitter will try to push that color to all the remaining connections. Only if the connection to the emitter is interrupted, it will look for a secondary source of energy.

Solution

• 
  Step 1: Connect the inverter to the red receiver and the rail drone.
• 
  Step 2: Go to the third room and grab the connector. Create a connection to the red receiver next to the progress wheel, but don't drop the connector yet.
• 
  Step 3: Come back to the second room and create connections to the blue emitter, blue receiver, and the inverter. Now you should have 4 active icons for your connector.
• 
  Step 4: Place the connector on the rail drone.
• 
  Step 5: Wait until the connector deactivates the blue door, then move into the inner room.
• 
  Step 6: Wait until connector activates the red receiver next to the progress wheel, then activate it.
