Robot, Fetch the Water

A robot's whole brain is a list of moves in the right order.

๐Ÿšถ โฌ†๏ธ โฌ†๏ธ โ†ช๏ธ โฌ†๏ธ ๐Ÿชฃ
Footprints drawn in the dust leading in a bent path to a bucket.

๐ŸŽ’ What you need

โœ‹ Do this

  1. Draw a start box on the ground. Put your robot friend in it, facing one way. Robots never turn on their own.
  2. You may only use four commands: FORWARD one step, TURN LEFT, TURN RIGHT, GRAB.
  3. Say the whole list BEFORE the robot moves. Once it starts, you may not speak.
  4. Run it. If it walks into the chair, that is not the robot's fault. Fix the list.
  5. When it works, count your commands and write the number in the dust. Then try to beat your own number.
  6. Hardest version: put an obstacle in the middle and get the water without touching it.

๐Ÿ’ก Why it works

A real robot receives commands exactly like this โ€” turn this wheel, move this arm, close this gripper โ€” with no idea what a bucket is. Getting the order right, before anything moves, is the entire job. The list you shouted is what a program looks like from the inside.

๐Ÿ”ฅ Challenge

Blindfold your robot friend. Same task, same four commands. Suddenly your list has to be perfect, because they cannot help you.
