Radio:
Goal: Inform Persuade Entertain Control Manage Educate
Source: Sounds and Information
Encoder: Devices that convert sound and info into a modulated sine wave (rapidly changing electric current in a wire)
Problem:
Sine wave contains no information.
We need to modulate (vary) it.

Mars Rover Exploration
Objective:
Be the first team to successfully create your required 3 mechanisms and deposit them where required.
Players (4 or 5):
THE ROVER
MARS
1 Classroom Exploration Robot (CER):
– No sight; only sound recognition and mobility
2 Mission Control (MC):
