Intro to Robotics Review

What is the primary definition of a "robot"?

• A machine that always requires programming to perform tasks

• A machine, often programmable, designed to perform a task with some level of autonomy, typically mimicking human capabilities

• A device that only operates in industrial settings

• An automated tool that never interacts with humans

Newton's First Law of Motion is also known as:

• The Law of Force and Acceleration

• The Action-Reaction Law

• The Law of Inertia

• The Law of Equilibrium

How much force is needed to accelerate a 1500 kg robotic vehicle at 5 m/s²?

• 300 N

• 7500 N

• 15000 N

• 3000 N

In the Bristle Bot example, what component is responsible for steering the robot?

• The battery

• The motor

• The googly eyes

• The pipe cleaner

What is the key requirement for an object to be in equilibrium according to statics?

• Constant velocity only

• The sum of all forces and moments (torques) must be zero

• Presence of friction

• Motion in a straight line

For a robotic arm lever where the effort arm is 30 cm and the load arm is 10 cm, what is the mechanical advantage?

• 0.33

• 3

• 40

• 20

Dynamics is the study of:

• How forces cause motion

• Objects at rest

• Energy storage only

• Rotational equilibrium

Which human organ system equivalent does the "frame" of a robot most closely mimic?

• Brain

• Muscles

• Skeleton

• Senses

A 10 kg load is towed up a 30° incline by a wheeled robot. What is the tension in the cable?

• 98 N

• 49 N

• 169.7 N

• 196 N

Which type of force in robotics is exerted by a contact surface to balance an object's weight?

• Applied Force

• Tension

• Normal Force

• Force of Friction
