Robotics Worksheet: Sense, Think, Act

Robotics lesson 2: Sense, think, act · Set 211 · 40 questions

Robot tip (The robot loop): Sense = taking in information with sensors (touch, light, sound, distance, camera). Think = the controller running the program and deciding. Act = doing something: motors move, a gripper grips, a buzzer beeps, a light shines. Then the loop starts again.

3. 3.🔍 Which is the odd one out? (a) it decides to stop (b) it counts the boxes (c) it decides to turn (d) the wheels spin
4. 4.🔢 To make a robot vacuum avoid a chair, which is the FIRST step? (a) the controller reads it (b) the bumper is pressed (c) it drives on (d) it decides to turn
5. 5.🧠 In which order does a robot work? (a) act → sense → think (b) sense → think → act (c) act → think → sense (d) think → act → sense

17. 17.Which of these shows that the robot is acting? (a) it counts the boxes (b) a bumper is pressed (c) the wheels spin (d) a mic hears a clap
18. 18.🔢 To make a robot vacuum avoid a chair, which comes first: “the motors turn it” or “it decides to turn”? (a) it decides to turn (b) the motors turn it
19. 19.🔍 Which is the odd one out? (a) a bumper is pressed (b) it compares two numbers (c) it plans the next move (d) it decides to stop
20. 20.True or false: when the robot turns left, the robot is sensing. (a) True (b) False
21. 21.🧠 Sense, think or act: “a mic hears a clap”? (a) think (b) sense (c) act
22. 22.🔍 Which is the odd one out? (a) it compares two numbers (b) it counts the boxes (c) it plans the next move (d) the arm lifts a box
23. 23.True or false: when it plans the next move, the robot is thinking (deciding). (a) False (b) True
24. 24.True or false: when a sensor checks distance, the robot is sensing. (a) True (b) False
25. 25.🔢 To make a robot vacuum avoid a chair, what comes right after “the bumper is pressed”? (a) it drives on (b) the motors turn it (c) the controller reads it (d) it decides to turn
26. 26.🔍 Which is the odd one out? (a) a bumper is pressed (b) it compares two numbers (c) a camera spots a wall (d) a sensor checks distance
