Ploy's First Robot

Ploy was an upper-elementary student who had loved building toys out of spare parts since she was little. This year, she joined her school's robotics club, determined to build a robot arm that could sort plastic bottles from paper for the annual science fair.

Ploy sketched her design excitedly, then built her first prototype using an old motor and a cardboard arm. But when she flipped the switch, the arm just flopped weakly, barely able to move at all. Her plan had failed on the very first try.

Ploy felt discouraged, especially when she saw a clubmate's robot working smoothly on its very first attempt. Disheartened, she secretly considered switching to a much simpler project instead.

The club's advisor noticed Ploy's discouraged face and came to sit beside her. "Almost every great invention failed many times before it worked," she said. "Try looking closer at *why* it didn't work, instead of giving up on it."

Ploy went back and tested each part carefully, one at a time. She discovered her motor was simply too weak to lift the heavy cardboard arm, so she rebuilt it using lightweight popsicle sticks instead.

Her second prototype could move, but it still sorted bottles and paper incorrectly much of the time. So Ploy tested it again and again with her family's real recycling at home, adjusting it a little more each time a problem showed up.

On the day of the fair, Ploy's robot actually worked. It was slow and far from perfect, but it correctly sorted a bottle from a piece of paper in front of the judges. Rather than pretending it had all been easy, Ploy told the judges honestly about every failed attempt along the way.

Ploy didn't win first place — a classmate's robot looked flashier — but the judges praised her problem-solving and honesty more than anyone else's. Win or not, Ploy felt proud of everything she had learned, and kept improving her robot just for the fun of it.
