  1. Castor Bot

  2. Now, we will begin creating a robot • Log onto your computer • On your screen, click on the website labeled “castor bot” • Your building instructions will be found there • Raise your hand if you need any help

  3. Now, that everyone has created a robot... • Please open your NXT program • Click “new program”

  4. We will now go through the basics on programming your robot

  5. How to program your robot

  6. Creating a new program… • You can create a new program or open a program you previously created. • Once you have a name for your program, select go!

  7. You should get a screen like this.

  8. Your work area • The Left bar is for putting blocks on your program • There are many different blocks, but we will go over the most basic ones first. • In the middle is our area where we do our programming. • We drag items onto the tracks.

  9. Please drag the movement block onto the track

  10. Using the Motion block • Has many parts. • The active ports. • Power • Direction: can be set to forward, reverse or stop. • Duration: controlled by: • Rotation • Degrees • Time • Steering: can adjust how hard a turn • Brake or coast modes.

  11. Ports What are ports? • Cables connecting brain to components A, B, C • Used for controlling motors 1,2,3,4 • Used for connect to the sensors • We will learn more about these later

  12. Changing ports and power • Depending on how many active motors you have connected, we check/uncheck Ports A, B, and/or C. • Power effects the speed of the motors.

  13. Controlling Direction What is it to control direction? Dragging the arrow left/right changes the direction that the robot will move. This feature is only active when two motors are selected. It controls forward, backward, or stop. How will changing the power effect the steering?

  14. Duration of activity Duration effects how long the block is active. Types of Duration Degrees Unlimited Time Rotation Let’s investigate!!
