Robot Kolunun Programlanması - C++

• This exploration will introduce students to basic programming of the V5 Clawbot's Arm Motor.

• Learning to program the Arm Motor enables students to properly control the V5 Clawbot's arm movements. For more information about the instructions used in a text program, visit the help information.

Model each of the troubleshooting steps for the students.

• Since this is a beginning activity with programming, the teacher should model the steps, and then ask the students complete the same actions. The teacher should then monitor the students to ensure that they are following the steps correctly.

• Make sure that the students have selected Open Examples from the File menu.

• Make sure that the students have selected the Clawbot Template (Drivetrain 2-motor, No Gyro) example project.

  You can point out to the students that there are several selections to pick from on the Examples page. As they build and use other robots, they will have a chance to use different templates.

• You can ask students to add their initials or the name of their group to the project name. This will help differentiate the projects if you ask the students to submit them.

• Point out that when they first opened VEXcode V5, the window was labeled MyProject1. MyProject1 is the default project name when VEXcode V5 is first opened. Once the project was renamed Drive and saved, the display was updated to show the new project name. Using this window in the toolbar, it is easy to check that the students are using the correct project.

• Tell the students that they are now ready to begin their first project. Explain to the students that by just following a few simple steps, they will be able to create and run a project that will raise and lower the Clawbot's arm.

• Remind students to save their projects as they work. This article from the VEX Robotics Knowledge Base explains saving practices in VEXcode V5.

This is a good point to pause and have the student groups review the steps that were just completed on starting a new project in VEXcode V5.

• If the students are using a computer, ask them now to disconnect the USB cable from the Robot Brain. Having the robot connected to a computer while running a project could cause the robot to pull on the connection cable.

Model running the project in front of the class before having all of the students try at once. Gather the students in one area and leave enough room for the Clawbot to move its arm. Demonstrate how to end the project and have the Clawbot's arm lower back to its resting position.

Tell the students it is now their turn to run their projects. Make sure that they have adequate space to safely have the Clawbot's arm raise.

The solution to the challenge is below. To lower the arm, students needed to change the “forward” parameter to “reverse” in the ArmMotor.spinFor(); instruction that was added.

// Begin project code
int main() {
  // Initializing Robot Configuration. DO NOT REMOVE!
  vexcodeInit();

  ArmMotor.setPosition(0, degrees);
  ArmMotor.spinFor(forward, 90, degrees);
  wait(2,seconds);
  ArmMotor.spinFor(reverse, 90, degrees);
  
}

Most of the instructions within this challenge are ArmMotor.spinFor();. After adding an instruction for moving the arm upward, and one for moving the arm downward, you can highlight the two instructions, right-click, and then choose to copy and paste them as many times as needed. Then the parameters can be changed to meet the challenge and wait(); instructions can be added between.

• Flight Traffic Controller Challenge Solution: 

// Begin project code
int main() {

  // Initializing Robot Configuration. DO NOT REMOVE!
  vexcodeInit();

  ArmMotor.setPosition(0, degrees);
  ArmMotor.spinFor(forward, 90, degrees);
  ArmMotor.spinFor(reverse, 90, degrees);
  wait(3, seconds)
  ArmMotor.spinFor(forward, 45, degrees);
  ArmMotor.spinFor(reverse, 45, degrees);
  ArmMotor.spinFor(forward, 45, degrees);
  ArmMotor.spinFor(reverse, 45, degrees);
  wait(5, seconds)
  ArmMotor.spinFor(forward, 90, degrees);
  ArmMotor.spinFor(reverse, 90, degrees);
  ArmMotor.spinFor(forward, 90, degrees);
  ArmMotor.spinFor(reverse, 90, degrees);
  ArmMotor.spinFor(forward, 90, degrees);
  ArmMotor.spinFor(reverse, 90, degrees);
  
 }
