ROBOTICS CLUB_QUALIFYING EXAM

Which programming concept allows a robot to make decisions based on sensor values?

• Events

• Sequence

• Broadcast

• Conditionals

A student's robot keeps crashing into walls despite having an ultrasonic sensor. What's the most likely issue?

• Line sensor is active

• Too many LEDs are on

• Gyroscope sensor is broken

• No logic checks for distance

Which of these will result in spinning in place clockwise?

• Left motor 0, right motor 100

• Left motor 100, right motor 100

• Left motor 100, right motor -100

• Left motor -100, right motor 100

If the gyro sensor returns unstable values, what might be the cause?

• Software error

• Poor calibration

• Weak ultrasonic signal

• Too much ambient light

In an 'if-else' structure, what happens if the condition is false?

• Code stops

• The robot resets

• The 'else' section runs

• The block skips to the end
