concept: the Earth's rotation
what everything represents:The sphere is the Earth, all the yellow Lego"s are the sun, what's happening is that the sun is giving the Earth light on each side after every single 24 hours, the other places get sunlight and we have the moon which means that we have night time and the other side of the Earth has daylight.
The mission of this robot is to detect the object and go back to its original sopt without dropping the object.
How do the electromagnet sensor and eye sensor work together?
The electromagnet sensor and eye sensor work together because the electromagnet sensor has a magnet on the robot and the disc so they get stuck together and the robot grabs the disc to take it back, and the eye sensor helps the electromagnet sensor because the eye sensor detects the disc color and it signals to the electromagnet sensor and that's how they work together.
