The document describes an activity called "Robot Writer" where groups of 2-8 people try to write a word together using a pen attached to a contraption made of tubes. Variations make the task more difficult, such as writing in cursive, adding mazes, or only allowing one person to see. The objectives are to brainstorm solutions, create something as a group, and discuss the experience. Guidelines, instructions, safety tips, and debriefing questions are provided to facilitate the activity.
