Robotics Basics
What is a robot?
A machine that can sense, think (process), and act automatically.
Which sensor allows a robot to detect colors?
Color sensor.
What programming structure uses “If this happens, then do this”?
Conditional (IF–THEN statement).
Name one place where robots are used to sort materials.
Recycling plant.
What is the first step in the engineering design process?
Identify the problem.
What are the three main parts of a robot system?
Sensor, Program (controller), Actuator (motor).
What does a color sensor measure to detect color?
Reflected light.
What should the robot do if it detects an unknown color?
Stop or signal (or another programmed response).
Why might color sorting be useful in recycling?
It separates materials quickly and accurately.
What does “iteration” mean in engineering?
Repeating and improving a design.
What is an actuator?
A device (like a motor) that moves or controls part of a robot.
Name one other common robot sensor besides a color sensor.
Touch sensor, ultrasonic sensor, light sensor, gyro sensor.
What is debugging?
Finding and fixing errors in code.
Name one industry that uses automation.
Manufacturing, agriculture, healthcare, logistics.
Why do engineers test prototypes?
To find problems and improve performance.
What makes a machine different from a robot?
A robot can sense and make decisions whereas a basic machine cannot.
Why might a color sensor give incorrect readings?
Lighting changes, dirty objects, similar shades.
What happens if you remove conditionals from a sorting robot program?
The robot cannot make decisions.
Why are robots often better than humans at repetitive tasks?
They are faster, consistent, and don’t get tired.
What tradeoff might exist in a sorting robot?
Speed vs accuracy.
What field combines engineering, coding, and problem-solving to build robots?
Robotics.
What type of sensor would you use to detect distance from an object?
Ultrasonic sensor.
Why is logic important in robotics?
It allows robots to make decisions based on sensor input.
What is one limitation robots have compared to humans?
Difficulty adapting to unexpected changes.
Why is teamwork important in robotics projects?
Different skills are needed (coding, building, testing).
