What is the formula for calculating a gear ratio?

of Driving Gear Teeth divided by # of Driven Gear Teeth

What will happen when you have a system with a Driving Gear that is larger than the Driven Gear?

You will increase SPEED and decrease TORQUE.

You will increase TORQUE and decrease SPEED.

How does a compound gear ratio change the mechanical advantage of speed or torque within a mechanism?

Multiples the mechanical advantage

Always doubles the mechanical advantage

Divides the mechanical advantage

Only decreases the mechanical advantage

What are idler gears?

Gears that change the direction of the rotation.

Gears that either increase or decrease the gear ratio.

The first or last gears of a gear train.

Gears that can increase or decrease speed or torque.

What can the drivetrain design affect?

how the robot moves around the field

How can turning scrub be reduced?

Make the wheelbase wider than longer.

Make the wheelbase longer than wider.

Make the wheelbase all the same length.

Make the wheelbase have a different width in the front and back of the robot.

How is turning scrub created?

Friction is created from the wheels dragging sideways on the ground.

Friction is created with when the wheels are moving forward.

Friction is created when the brakes of the robot are applied.

Friction is created from air particles in the air.

What is a robotics lift?

A mechanical system in the robot that allows the change of positioning of another mechanism or object.

A mechanical system in the robot typically used with a claw, intake, or launcher to move, place, reposition, or retrieve objects to places the robot would otherwise be unable to reach that

A mechanical system in the robot assembled to lift other manipulators vertically or to lift the robot off the ground.

What are the main categories of lifting mechanisms?

Linkages, rotating joint, elevators

Rotating joints, swing arms, elevators, bar arms, linkages, scissors

Swing arms, 4-bar arms, scissors

4-bar arms, 6-bar arm, 8-bar arm, double reverse 4-bar arm

Arms that involve more than one pivoting bar which makes connections between a tower and an end tower.

A lift that uses linear motion to raise a set of linear slides vertically.

A single arm connected to gears that rotate between two structures or towers.

A series of two beams attached together at the center called stages.

What happens to the arm when using a linkage?

The arm is lifting relatively level. However, the arm does move in a slight arc as it lifts.

The arm is not lifting relatively level and the arm moves in a slight arc as it lifts.

The arm is lifting relatively level and the arm does not move in an arc as it lifts.

The arm design passes over the top of the tower and reaches the other side of the robot.

How are double reverse arm lifts usually assembled?

as pairs to equalize the forces on the arms

as stages to equalize the forces on the arms

as pairs to combine the forces on the arms

as polar opposites to equalize the forces on the arms

What is a double reverse 4-bar arm lift?

A four bar linkage with the end linkage serving as a second tower for a top set of four bars.

A lift that uses linear motion to raise a set of linear slides vertically.

A series of two beams attached together at the center called stages.

A single arm connected to gears that rotate between two structures or towers.

How does the double reverse 4-bar prevent the robot from tipping over?

It keeps the weight of a load centered over the base of the robot.

It keeps the weight of a load in front of the robot.

It keeps the weight of a load in the back of the robot.

It keeps the weight of a load at the sides of the robot.

When adding more linkages to a scissor lift, it will:

Increase the distance it can extend but decrease its stability.

Increase the distance it can extend and increase its stability.

Decrease the distance it can extend but increase its stability.

Decrease the distance it can extend and decrease its stability.

How do scissor lifts change the direction of a force?

Horizontal force makes the scissor lift move vertically.

Vertical force makes the scissor lift move horizontally.

Inside forces make the scissor lift move outside forces.

Outside forces make the scissor lift move inside forces.
