News Detective: Dancing with Robots

Sarah checks out a robot competition.

I think I was 10 when I built my first and only robot. His name was Tinker, and he was made entirely of Tinkertoy parts. My dad had helped me rig up a motor and a rubber band that allowed him to roll around on hard floors.

Tinker wasn't actually a robot. Although he could move, he had no real intelligence. He didn't have a computer, and I couldn't program him to move forward, turn, or stop. He simply rolled every time I plugged in the 9-volt battery.
