Motomo Lab 1
Objective
Learn to control the motor with its new feature, the servo. This will allow to turn different directions using angles.
Activity
Students will learn to turn motomo using a servo.
Assessment
Students will learn to analyze problems.
Students will learn to handle a servo using the angles and its limitations.

Welcome to our first Motomo Lab! In this lab we will learn about servos and why they are so useful in our day to day. We will also learn how to handle them using angles.

First Locate the servo. The servo is the brown cube on top of the front wheel. This servo is called MG90S. There are all types of servos ours can only turn from 0 to 180 degrees. Other servos can turn all around and some are built to lift heavy materials.
A servo is a DC motor that has been built to move accurately instead of infinetly turning. This allows us to code the servo to move to very specific directions fast and accurately. In our case, the library built for the servo is built to go from -90 degrees to 90 degrees. This means 0 degrees the wheel will point forward, -90 will point left, and 90 will point right. For any troubleshooting with angles and hardware refer to our troubleshooting page.

To code for the robot, make sure the library YYLibs is installed into your C2G mini. This library allows to code for the servo and change its angles. Try seting up the servo blocks and change the angles to see if you can master the movement!
Step 3
Lastly, try to combine servo movement and DC motor movement. What the robot go left and right with the new hardware! Tips: For one motor, we will only have to the the motor to go forwards or backwards since the servo will be in charge of the turning.
