WorksheetsReview Questions Lesson 7: Manipulators & End Effectors
Total questions: 10
Worksheet time: 8mins
What is the fundamental relationship between a manipulator and an end effector on a robot?
The manipulator is the ‘hand’ of the robot, and the end effector is the ‘arm’.
The end effector is a specialized tool attached to the end of the manipulator.
A manipulator is a passive component, while an end effector is always an active component.
They are two names for the same component, also known as a robot arm.
A team builds a simple, non-motorized hook on the end of their robot's arm to pull a game piece. How is this component best classified?
An intake manipulator
An active end effector
A continuous roller
A passive end effector
What is a primary advantage of a horizontal roller intake?
It is the only design that can be reversed to outtake objects.
It maintains constant contact with objects, providing flexibility in manipulation.
It requires fewer materials and is more compact because it uses the floor as one side.
It can accommodate objects of various shapes without needing precise alignment.
A robot is designed to collect objects that are always on the ground. Its intake uses the floor as one surface to help guide objects in. What is a likely disadvantage of this design choice?
The mechanism might jam if multiple objects are not perfectly aligned.
It is much heavier than other intake designs due to its intricate components.
The two rollers require careful synchronization to work effectively.
It is less effective at capturing objects that are not on the floor or are at varying heights.
An intake mechanism, which uses a motor to spin rollers that pull in objects, is a specific type of which broader category?
Active end effector
Passive end effector
Robot Chassis
Robot Manipulator
How does a typical roller intake mechanism achieve the 'outtake' function to release an object?
By reversing the direction of the motor that powers the intake.
It relies on a separate pneumatic cylinder to push the object out.
It uses a mechanical clutch to disengage the rollers, allowing the object to fall.
It requires a second motor that is geared to spin in the opposite direction.
Which design consideration is most critical when determining the necessary force an intake needs to successfully pull in an object?
The number of objects you want to gather at one time.
The shape of the object you are trying to collect.
The types of parts you have available for building.
The weight of the object you are trying to collect.
A robot design that features two rotating sprockets with chains and rubber flaps to 'slap' objects into a container is an example of which mechanism?
A vertical roller intake
A continuous roller intake
A passive plow effector
A horizontal roller intake
Why might a robotics team choose to build a passive end effector instead of an active one?
It offers greater precision and control for complex tasks.
It is generally easier to build and adds less weight to the robot.
It can grab and lift objects more effectively.
It is more adaptable to objects of various shapes and sizes.
Which intake design is described as being more intricate, taking longer to assemble, and having a risk of jamming if objects are not aligned properly?
A horizontal roller intake
Plow design intake
Vertical roller intake
Continuous roller intake
