How Do Robots Talk to Each Other?

When you want to tell your friend a secret, you use your voice. But robots don’t have vocal cords. Instead, they talk using invisible waves in the air!

Robots use Wi-Fi, Bluetooth, or Radio waves to send messages back and forth. For example, if you use a remote control to drive a toy car, the remote is flashing an invisible radio wave to the car’s antenna, yelling ‘GO FORWARD!’ in computer language (1s and 0s).

If you join a FIRST® Robotics team, you’ll learn how to connect your gamepads to a robot using these invisible radio signals to control its every move!
