Intro to Robotics Final Exam Review

What is the definition of a robot?

A re-programmable machine that can do repetitive work, without getting tired, at a high rate of accuracy.

What are the three major parts of a robot?

Manipulator, controller, and power supply

What are the four main parts of the manipulator?

Waist, shoulder, elbow, and wrist

What is the purpose of the controller?

It is the brain

What does the power supply do in a robot?

provides the energy for the robot to do work

What is the purpose of the drive system in a robot?

move the manipulator

Left and right movement of the robot wrist is called?

yaw

What type of robot drive system can lift the heaviest payloads?

Hydraulic

What is the point called where two parts of a robot are connected and move?

joint

What is the importance of having sensors on a robot?

Allow the robot to be more responsive, to make decisions while operating, and to make it more like people

What is a simple definition of a sensor?

any device that has the ability to detect and respond to physical stimulus

Why are sensors necessary in both the aviation and space industries?

1) to make sure specific aspects of flight are maintained and assure safe travel

2) To communicate to a flight crew the current operating characteristics of an aircraft

3)Allow for automatic adjustment in the operating characteristics of an aircraft

What is a "closed-loop" servo system?

A system that sends an electronic signal to a computer for comparison

In what situation is a closed-loop servo system used?

Anywhere a feedback signal is necessary

What is a "non-contact" sensor?

A device that does NOT require physical touch to operate correctly

What is a "contact" type sensor?

A device that does require physical touch - presently one of the most popular types of sensors because of the use of touch screens

What is artificial intelligence?

provides machines more information so they can make more complicated decisions

Where is "Artificial Intelligence" used?

in any situatoin where it is necessary to provide machines more information so they can make more complicated decisions

What is the purpose of a "feedback loop" in a sensing system?

to allow a machine to make instantaneous changes in its operation

What type of sensor uses small black stripes to gather information?

barcode sensor

What is the best type of sensor to use to measure the grip of a robot's hand?

force sensor

Small strands of glass bundled together to transmit signals using light are called what?

fiber optics

What type of sensor uses a single frequency light source?

infrared sensor

What sensor is best for controlling the movement of a cyllinder or piston?

macnetic sensor

How does a photoelectric sensor work?

When a light source shining on a detector is interrupted, a signal is generated in the detector that can be used as information

What type of sensor can measure pressure of gasses, liquids, or solids?

pressure sensor

Which type of sensor detects reflected waves off of nearby objects?

proximity sensor

What type of sensor produces a signal based on the movement of air across its surface?

sound sensor

The use of a thermometer or thermocouple is associated with what type of sensor?

temperature sensor

Which sensor type allows people to directly interact with the computer inside an iPod?

touch sensor

What sensor can be used to provide a machine, like a robot, with the ability to sense an image.

vision sensor

If more sensors are connected to the NXT robot, will the complexity of the program increase?

yes

Is it possible for the NXT brick to use more than one sensor in a program?

yes - up to 4

What is the purpose of the NXT "brick", what is it, and what can it do for the Lego robot?

it is the controller that can be programmed to make a robot run

What are the "Motors, Turn and Stop" program blocks used for?

they make a motor start turning, turn opposite directions, and stop turning

How are the "Sound sensor and Ultrasonic sensor" blocks used in NXT programing?

they can be used to wait until one of those sensors reaches a certain value to make a motor stop or start

What does the term "Computer Aided Design" mean?

A method used in Architecture, Mechanical Engineering, and Civil Engineering to design products, allows engineers the ability to show in 3D design before physically prototyping, replaces hand drawings with an automated process

In what field is CAD used in?

Agriculture, automotive, aerospace, manufacturing, architecture

What different CAD softwares are available?

OnShape, Solidworks, AutoCAD, Rhino, Sketchup, CADD, Microstation, Revit

When designing on OnShape, what is generally the first thing you do to start a design?

Create a sketch

When designing in Onshape, the term Plane refers to what?

A 2D surface used in sketching

Which manufacturing process do our 3D printers utilize

Additive Manufacturing

When designing with OnShape, you can use any manufacturing process to create a design.

True, keeping in mind how things are made is important and helps with design

The viewcube allows you to

Orient the workspace to any view of an object

What tool is used to create rounded corners in an object

Fillet tool

What is the tool used to constrain the size to a specific measurement of an object?

Dimension tool
