Space
What does “autonomous” mean in the context of robotics?
Controlled by a human using a remote
Programmed to move randomly
Able to operate independently
Built by a human with tools
Which step of the Engineering Design Process comes after planning?
Improving
Testing
Building
Researching
What is the main function of gears in a robot?
To control electricity
To manage speed and force
To power batteries
To connect sensors to the brain
If a robot needs to lift something heavy, what type of gear setup is best?
Large gear driving small gear
Small gear driving large gear
Two equal-sized gears
No gears at all
When a large gear turns a small gear, what happens to speed and torque?
Speed increases, torque increases
Speed decreases, torque increases
Speed increases, torque decreases
Speed and torque stay the same
Which mechanical system helps lift weight by spreading out the effort over distance?
Gear
Pulley
Sensor
Motor
What is one advantage of block-based coding for students?
It requires no internet
It helps robots recharge
It is easier to understand than text coding
It allows students to build motors
What does an ultrasonic sensor detect?
Light
Sound
Temperature
Distance
Which sensor would help a robot follow a path marked on the floor?
Ultrasonic sensor
Touch sensor
Light sensor
Temperature sensor
What is the function of a motor in a robot?
To process information
To move parts of the robot
To store data
To detect objects
Which of the following is a benefit of using sensors in robots?
They reduce battery usage
They help robots make decisions based on the environment
They prevent robots from needing code
They improve the color of the robot
A gear train includes a driver gear with 10 teeth and a driven gear with 20 teeth. What happens to the speed of the system?
Speed increases
Speed stays the same
Speed decreases
The gears will not move
In the Engineering Design Process, what is the purpose of the "test" phase?
To build the robot
To brainstorm solutions
To see if the design works as intended
To paint the robot
Which tool would be most helpful when measuring the length of a robot arm?
Thermometer
Stopwatch
Ruler or measuring tape
Magnet
If a robot is not turning as expected, what is the first step you should take?
Replace the battery
Rebuild the robot
Check the code and motor connections
Add more weight
What does a loop (or repeat block) do in programming?
Stops the program
Tells the robot to turn
Runs the same command multiple times
Connects the robot to the internet
What is torque?
The robot's battery level
The speed of a spinning gear
The force that causes rotation
The color of a sensor
Why are prototypes important in robotics?
They are the final product
They help test ideas before finalizing a design
They replace programming
They are used only for decoration
A student builds a robot with wheels powered by two motors. One motor turns faster than the other. What will happen?
The robot will move straight
The robot will spin in a circle
The robot will fly
The robot will stop moving
What is the first step in the Engineering Design Process?
Build a prototype
Brainstorm solutions
Identify the problem
Test the final design
Why is it important to test a prototype?
To make sure the robot looks good
To see if the design works and identify problems
To skip to the final product
To sell it to others
What does it mean to iterate a design?
Build something brand new
Use someone else’s design
Improve the design based on test results
Finish the project early
During which step do students usually sketch or plan how their robot will look or work?
Ask questions
Create a prototype
Brainstorm and plan
Share results
