Week 12 Quiz: miniAuto Movement Programming

Question 1: Mecanum Wheels

What makes Mecanum wheels different from regular wheels?

A) They are larger and heavier B) They have rollers at 45° angles enabling omnidirectional movement C) They only rotate in one direction D) They require special motors to operate

Question 2: Motor Control Pins

How many motors does the miniAuto have and what types of pins control them?

A) 2 motors controlled by analog pins only B) 4 motors controlled by PWM pins and direction pins C) 6 motors controlled by digital pins only D) 3 motors controlled by servo pins

Question 3: Sideways Movement

What wheel pattern creates sideways movement to the left?

A) All wheels rotate forward B) Front left and rear right backward, front right and rear left forward C) Left wheels forward, right wheels backward D) All wheels rotate backward

Question 4: Rotation Movement

How do you make the miniAuto rotate clockwise in place?

A) All wheels rotate in the same direction B) Left wheels forward, right wheels backward C) Right wheels backward, left wheels forward D) Only the front wheels move

Question 5: PWM vs Direction Pins

What's the difference between PWM pins and direction pins in motor control?

A) PWM controls speed, direction pins control forward/backward B) PWM controls direction, direction pins control speed C) Both control the same thing D) PWM is for servos, direction pins are for DC motors

Question 6: Arduino Functions

Which Arduino function is used to control motor speed?

A) digitalWrite() B) analogWrite() C) digitalRead() D) analogRead()

Question 7: Movement Sequences

In the movement demonstration program, what happens between each movement command?

A) The robot immediately starts the next movement B) The robot stops motors and delays before the next movement C) The robot waits for user input D) The robot resets to starting position

Question 8: Motor Safety

What is the purpose of the stopMotors() function?

A) To increase motor speed B) To set all motor PWM values to 0 for safety C) To change motor direction D) To reset the Arduino

Question 9: Movement Pattern Design

Describe how you would program the miniAuto to move in a square pattern. Include the specific movement functions and timing you would use.

Question 10: Troubleshooting Movement

If your miniAuto is not moving correctly (e.g., going in circles instead of straight), what are three possible causes and how would you fix them?
