Understanding Machine Athleticism

What is the main reason quadrocopters are popular?

• They are very expensive.

• They are mechanically simple.

• They are very large.

• They are difficult to control.

What is required for quadrocopters to fly due to their inherent instability?

• Manual control by a human.

• Automatic feedback control.

• Larger propellers.

• More powerful batteries.

What is used as an indoor global positioning system for the quadrocopters?

• GPS satellites.

• Cameras on the ceiling and a laptop.

• A smartphone app.

• A handheld remote control.

What branch of mathematics is used to design algorithms for controlling quadrocopters?

• Algebra.

• Geometry.

• Control theory.

• Calculus.

What is the purpose of adding a mathematical model of the pole to the quadrocopter system?

• To make the quadrocopter fly faster.

• To stabilise the quadrocopter.

• To balance the pole.

• To increase battery life.

Why doesn't the water fall out of the glass when placed on the quadrocopter?

• The glass is glued to the quadrocopter.

• The propellers create a vacuum.

• Gravity and propeller direction minimise side forces.

• The glass is very heavy.

What is the minimum number of fixed motor propeller pairs needed for a quadrocopter to fly?

• Two.

• Three.

• Four.

• Six.

What happens when a quadrocopter performs a triple flip?

• It uses position feedback to correct motion.

• It performs the maneuver blindly and learns from it.

• It stops mid-air to adjust.

• It requires manual intervention.

How often are calculations made when a quadrocopter hits a ball?

• Every 10 milliseconds.

• Every 20 milliseconds.

• Every 50 milliseconds.

• Every 100 milliseconds.

What do three quadrocopters cooperatively carry in the demonstration?

• A large net.

• A sky net.

• A parachute.

• A camera.
