Vex Robotics Programming Sequence

Now that you’ve had some practice downloading and using the included programs, it's time to learn to write some of your own! These are the three basic steps you will follow each time you create a new program for your robot.

Writing your first program Start simple. For your first program, you will learn how to turn a single motor on.

Launch easyC and select “New Project” from the “File” menu.

Select “L2” on the toolbar.

In the Function Blocks window (leftmost panel in the main window), under the “Outputs” heading, find the “Motor - Motor Module” block.

Left-click and drag the “Motor - Motor Module” block into the program window, between the Begin and End blocks. Release the block there.

The motor module configuration window will appear. Make sure “Motor Number” is 3 and “Clockwise” is selected. Click “OK.”

Your program should now look like this:

Make sure your hardware is set up properly and the robot is turned on. Select the “Build and Download” option in the “Build and Download” menu. Click “Yes” on download HEX file confirmation.

As soon as your program finishes downloading, the left motor will turn on, making your robot spin in place. To make it stop running, switch off the robot.

Now that your robot is off, you can unplug the wire from the serial port on the Vex Micro Controller and place your robot somewhere safe (for example, the floor). To run your program again, switch the robot back on.

Close the IFI/intelitek Loader by clicking on the. Save your program as “intro program one” by following the steps on the next page.
