EASY C GETTING STARTED The program allows programmers to

enable the joystick or to disable it. Use a new standalone project and then select either joystick or autonomous. In some cases, the robot can run automatically unless interrupted by the joystick. This could be a good idea in case a robot “accidentally” runs amuck.

Using the Development Environment

The fancy programming environment starts off with the robot doing nothing. However, it gives us some ideas of where things can go. For now, code will be placed just before the “end” flag. The first objective will utilize Output functions and Program Flow functions. Studentsmay explore otherfunction types, however they are notrequired yet.

Outputting to the MotorAdd a motor module to your program. The

motor module comes with two variables. The first says what motor will be used. The second describes the voltage. Using a negative number will reverse the voltage and make the motor spin the other way. To make more than one motor move, the programmer will need to add more than one motor module. Look on the robot to see what numberthe motors are.

UPLOADING THE PROGRAM When you have a program, plug in the

robot with the orange tethering cord to the main CPU. Then, use the build and download program to send the program to the robot. Try to make a program that will have the robot move forward, move backwards and turn around. Try to find ways to output to all the motors on the bot.

Mission Objective

In this mission the robot will function in automatic mode. The robot will start on one side of the hall. It will then go back and forth to end up on the far side of the hall. It will then stop with the program ending. Score will be based on the following formula:

Score = 105 – seconds That means that a robot that does the

mission in 6 seconds gets a 99% for the grade.
