Basic Movement

Which of the following components are ESSENTIAL in making the robot move?

• 
• 
• 
• 
• 

​ (a)   is the rate at which objects move. ​ (b)   is equal to ​ (c)   over ​ (d)   . ​ (e)   can be controlled by changing the power setting in the sketch.

• Speed
• distance
• time

What does this section of the sketch do?

int lMotorA = 5;

int lMotorB = 9;

int rMotorA = 6;

int rMotorB = 10;

• Assign different power settings to the motors.

• Assign digital I/O pins to motor pins.

• Assign analog pins to motor pins.

• Assign delay values to motors.

• Assign variable names to digital I/O pins.

What does this section of the sketch do?

void setup() {

pinMode(lMotorA, OUTPUT);

pinMode(lMotorB, OUTPUT);

pinMode(rMotorA, OUTPUT);

pinMode(rMotorB, OUTPUT);

}

• Configures motor pins as OUTPUT pins.

• Converts motor pins to OUTPUT pins.

• Creates motor pins from OUTPUT pins.

• Assigns the OUTPUT value to the motor pins.

Complete the codes with the missing values if you want your robot to move forward for half a second and stop for 1 second.

void loop() {

forward();

delay(​ (a)   );

stop();

delay(​ (b)   );

}

• 500
• 1000
• 0.5
• 1
• 100

Which of the following is a correct forward () function?

• forward() {

  analogWrite(lMotorA, 128);

  analogWrite(lMotorB, 0);

  analogWrite(rMotorA, 128);

  analogWrite(rMotorB, 0);

  }

• void forward() {

  analogWrite(lMotorA, 128);

  analogWrite(lMotorB, 0);

  analogWrite(rMotorA, 128);

  analogWrite(rMotorB, 0);

  }

• forward {

  analogWrite(lMotorA, 128);

  analogWrite(lMotorB, 0);

  analogWrite(rMotorA, 128);

  analogWrite(rMotorB, 0);

  }

• void forward {

  analogWrite(lMotorA, 128);

  analogWrite(lMotorB, 0);

  analogWrite(rMotorA, 128);

  analogWrite(rMotorB, 0);

  }

• forward(

  analogWrite(lMotorA, 128);

  analogWrite(lMotorB, 0);

  analogWrite(rMotorA, 128);

  analogWrite(rMotorB, 0);

  )

How would you describe your robotics skills in terms of assembly and wiring?

• SUNNY. Everything is clear.

• CLOUDY. I need to clarify some things.

• RAINY. I need to fix some things.

• STORMY. I need to go through it again.

How would you describe your robotics skills in terms of programming?

• SUNNY. Everything is clear.

• CLOUDY. I need to clarify some things.

• RAINY. I need to fix some things.

• STORMY. I need to go through it again.

How would you describe your robotics skills in terms of troubleshooting your robot, both hardware and software?

• SUNNY. Everything is in working order.

• CLOUDY. I need to change some things but I know what to do.

• RAINY. I need to fix some things and I need help.

• STORMY. I need to go through it again.
