Question:

“The following commands are used to make Leanbot perform a sequence of actions. Select all the correct outcomes:

Leanbot.begin();  

LbGripper.close();  

LbMotion.runLR(-400, -400);  

LbMotion.stopAndWait();  

LbMission.end();

Question:

“Which of the following best describes the Internet of Things (IoT)?”

Question:

Match the following Leanbot actions with the corresponding commands:

Description: Leanbot uses commands to perform actions. Actions like picking up objects and controlling movement are executed by specific commands.

Commands:

• LbGripper.open();
• LbGripper.close();
• LbMotion.runLR(+400, -400); LbMotion.waitRotationDeg(90); 
• LbMotion.runLR(-400, -400);
• LbMotion.stopAndWait();

Actions:

• Open the grippers
• Close the grippers.
• Turn right.
• Move backward.
• Stop.

Question:

“Robots can be programmed to perform repetitive tasks more efficiently than humans.”

Question:

“Which of the following is a key principle of ethical AI?”

Question:

“The following code is written to make Leanbot pick up an object, rotate left, and stop. However, there is a bug in the sequence. Identify and fix the bug:

Leanbot.begin();  

LbGripper.close();  

LbMotion.runLR(+400, +400);  

LbMotion.stopAndWait();  

LbMission.end();

(LbMotion.runLR(vL, vR) specifies the speed of the left (vL) and right (vR) wheels.

• Positive (+): Robot moves forward.
• Negative (-): Robot moves backward.)

What change(s) are needed to make the program work as intended?”

Question:

Complete the command sequence to make Leanbot rotate right and stop:

Leanbot.begin();  

;  

LbMotion.waitRotationDeg(90);

LbMotion.stopAndWait();  

LbMission.end();

Description:
Leanbot uses commands like LbMotion.runLR(vL,vR) to control movement, where vL and vR are speeds for the left and right wheels. 

• Positive (+): Moves forward.
• Negative (-): Moves backward.
