For example, if you move the slider all the way to the right and select “10” because you’re having an amazing day, Droid will automatically light up green. Then the robot’s lights will fade to a color that represents the aggregate mood of everyone who voted so far that day. And because the droid’s LEDs are equidistant, Christian can easily draw other patterns like logos, letters or even animations.
The project serves as a conversation starter with colleagues, enables them to check in with themselves about how they’re feeling and even inspires them to use technology in a creative way to solve real problems. But the best part of building the bot was bonding with his daughter and teaching her important lessons.
“I hoped she’d have fun, pick up a thing or two about technology and math and learn that it’s OK to not get it right straight away,” Christian says. “For example, cutting 30 pieces of plywood to the wrong size because of a measuring mistake is not a failure, it’s a lesson for next time.”
