VEX EXP Robot Soccer: Lesson 2 Quiz

Which of the following best describes a manipulator?

• Two motors that function as if they are one device

• A mechanical sensor that reports if it is pressed or not pressed

• A mechanism designed to manipulate an object to complete a specific task

• A sensor capable of detecting ‘capacitive’ touch

The effectiveness of a manipulator is dependent on (a)   .

• The object it is meant to interact with

• The task it is meant to accomplish

• The number of pieces used to build it

• Both A & B

Which of the following is NOT a consideration when designing a manipulator?

• The color of the object being manipulated

• The size and shape of the object being manipulated

• The way the object is meant to be moved

• The weight of the manipulator on your robot

4. A (a)   manipulator has (b)   attached to it.

• Passive; a motor

• Intake; no motor

Which of the following is true of an active manipulator?

• It has no motors attached to it

• It is not useful for lifting an object

An intake is an example of a (a)   manipulator.

• Drivetrain

• Active

• Passive

• Unpowered

Which of the following is NOT a consideration when designing an intake for your robot?

• The parts you have available

• The weight of the object you are trying to collect

• The shape of the object being collected

• The color of the object being gathered

In the project shown here, what will the intake do when the R1 button is pressed?

• The intake will stop spinning

• The intake will spin out to push out an object

• The intake will spin in to pull in an object

• The intake will slow down to 50% velocity

Which of the following is NOT an example of a usage for an intake on a robot?

• To push out an object to score a goal in a game

• To navigate around an immovable object

• To collect multiple objects at once to move them across a Field

• It is a type of gripper that is used to pick up and transport objects

• It consists of two motors that are going to function as if they are one device

• It is a decision made from observable and measurable data

• It is a device where each motor must be coded individually
