I wanted to share my Hide and Seek robots with the forum.
I’m using Pololu motors, motor drivers, A* boards and IR proximity sensors. The bumpers are using contact switches and a voltage divider. A ‘snap’ switch gets the game started via the microphones. They both spin a 180 and the Hider takes off at high speed while the Seeker counts out 30 beeps on the piezo buzzer. After 30 seconds the Hider stops, does another 180 spin, and starts pulsing its proximity sensors at a rate of 500usec. The Seeker then searches for the Hider using its proximity sensors to home in on the Hider’s signal. When the Seeker eventually bumps into the Hider, the Hider will spin to face the point of contact and the Seeker will start counting pulses. If the count reaches a certain threshold the Seeker does a celebratory light show and the game is over…
It was a lot of fun to make them and a great learning experience.
