This activity will give you the tools to program your Controller.

You can use the Help information inside of VEXcode V5 to learn about the blocks. For guidance in using the Help feature, see the Using Help tutorial.

Step 1: Let's start programming the Controller.

  • Start by watching the Using Loops tutorial video.

  • Open the Tank Drive example project.

    Do the following in your engineering notebook:

    Predict what the project will have the Clawbot do. Explain more than the fact that the project utilizes the Controller.
    How do the joysticks move the robot? What is the Clawbot doing?

  • Save, download, and run the Tank Drive example project.

  • For help, see the tutorial in VEXcode V5  that explains how to Download and Run a Project.

  • Check your explanations of the project in your engineering notebook and add notes to correct them as needed.

Step 2: Controller: Tank Drive

What are the benefits of using the [forever] block?

Here is our project without the [forever] block:

What do you think would happen if this program were run? Discuss as a group. Write down your prediction in the engineering notebook.

Step 3: Navigate a Slalom Course!

Slaloms are courses which the participant must navigate around the set flags, or markers. Ski slaloms are a popular winter sport and are included in the Winter Olympics.

Now that the Controller is paired and the project is downloaded, you are ready to move your Clawbot using the Controller!

  • Collect the four classroom items you will use as flags in your slalom from the teacher.

  • Collaborate to set the flags in place for the Driver to navigate the Clawbot around, according to the slalom diagram.

  • Download Tank Drive Example project. If there are any questions about how to download a project, check out the Download and Run a Project tutorial.

Step 4: Robo-Slalom

Use the Controller to move your Clawbot along the outside of each “flag.” The robot’s path must prevent it from touching any flag, and allow it to cross the finish line.

  • Run the project and drive the Clawbot forward and reverse, and turn left and right using both Joysticks.

  • Time how long it takes for the Clawbot to complete the course. Document the times in the engineering notebook.

  • How fast can you get Clawbot through the Slalom course?
