Introduction: 3 Basics of Building a Robot

Picture of 3 Basics of Building a Robot

Step 1: The Input

Picture of The Input

To have an input you will need a sensor to have as an input. Your sensor could be a switch, ultrasonic sensor, potentiometer, etc,.

Step 2: The Processor

Picture of The Processor

This is the brains of the operation. You can use an arduino or another simple circuit that will control your output. This is just simply a circuit that will take the input and turn it into an output.

Step 3: The Output

Picture of The Output

This uses the output from the processor and uses it to do something. This could be a servo or an led.

Step 4: Example

Picture of Example

This is an example you can do if you have the Board Of Education Shield kit by parallax. I used one of their projects as an example. In the project the input is an inferred detector and uses an arduino to process the signal that comes in when ever a light is shined in and the stops the servo output. You press reset and the servos go until a light is shined at the infrared detector and that is processed and the servos are stopped.
