Drive Bases
What is the main purpose of a robot's drive base?
To support the robot and allow it to move around the field.
What is a robot mechanism designed to interact with game objects called?
A manipulator.
What mechanical components have teeth and transfer rotational motion from one axle to another?
Gears.
A robot arm rotates around a pivot point. Which simple machine does it act like?
A lever
How many points is one Bean Bag worth when scored in a Floor Goal?
Answer: 1 point.
What type of drivetrain controls the left and right sides of the robot separately?
What manipulator uses spinning wheels or rollers to pull an object into the robot?
A roller intake.
When a small gear drives a larger gear, what does the output generally gain?
Torque.
The wheels and axles on a robot's drivetrain are an example of which simple machine?
Wheel and axle.
How many points are Bean Bags worth on L1, L2, L3, and L4?
What happens when a drivetrain uses larger wheels while keeping the same motor speed?
The robot can travel faster because it moves farther with each wheel rotation.
: What manipulator closes around an object to hold it securely?
A claw or grabber.
What is a mechanism made of connected bars that transfers or changes motion?
A linkage.
A ramp lets an object move upward gradually instead of being lifted straight up. What simple machine is the ramp?
An inclined plane.

An Arm
If two gears are directly meshed together, do they rotate in the same direction or opposite directions?
Opposite directions.
On a lever, what is the name of the point that the lever rotates around?
The fulcrum.
How many Bean Bags may a Robot possess or plow at one time during Level Up?
One Bean Bag.
Two robots use the same motors. Robot A is geared for speed and Robot B is geared for torque. Which robot would generally be better at pushing another object?
Robot B, the torque-geared robot.
For Level Up, your robot needs to pick a Bean Bag up from the floor and then place it on a high Goal. What two major manipulator functions would you probably need?
An intake and a lifting mechanism, such as an arm or elevator.
A motor turns clockwise. You want the final output axle to also turn clockwise using ordinary gears. What is the minimum number of gears you need?
Answer: Three gears.
A mechanism allows you to use less force to lift an object, but you must move the mechanism a greater distance. What concept describes this advantage?
Mechanical advantage.
What is Part A of the R16 Vex Iq game rule?
You may not have more than two air tanks including ones that are not connected.
