Question:

The following code is written to make Leanbot move forward 10cm -> stop for 2 seconds -> pick up an object -> turn right 180 degrees -> stop for 2 seconds -> move forward 10cm -> stop -> then drop an object. ( End) “.

Code: 

Leanbot.begin();  

LbMotion.runLR(+1000, +1000);  

LbMotion.delayDistanceMm(100);

LbMotion.stopAndWait();

LbDelay(2000);

LbGripper.close(); 

LbMotion.runLR(+500, -500); 

LbMotion.waitRotationDeg(180);   

LbMotion.stopAndWait();    

LbDelay(2000);

LbMotion.runLR(+1000, +1000); 

LbMotion.delayDistanceMm(100);

LbMotion.stopAndWait();

LbGripper.open(); 

LbMission.end();

Description: 

  • LbMotion.runLR(vL, vR); controls movement, where vL (left wheel) and vR (right wheel):
    • Positive (+): Moves forward.
    • Negative (-): Moves backward.

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

Question:

Complete the command sequence to make Leanbot pick up an object, move forward, and rotate right.

  • Leanbot.begin();
  • ;  
  • LbMotion.runLR(+400, +400);
  • LbMotion.waitDistanceMm(100);  
  • LbGripper.open();
  • LbMotion.runLR(+400, -400);
  • LbMotion.waitRotationDeg(90);   
  • LbMotion.stopAndWait();  
  • LbMission.end();

Description:
Leanbot commands allow it to perform a sequence of actions. The LbMotion.runLR(vL, vR) initializes movement, LbMotion.WaitDistanceMm() specifies distance, and LbGripper commands control object manipulation.

Word List:

  • LbMotion.runLR(+400, +400)
  • LbMotion.runLR(-400, -400)
  • LbGripper.close()
  • LbMotion.stopAndWait()

Choose 1 of 4 content sections in the Word List to fill in the blanks (type by hand or copy).

3 / 7

Question:

Match the following Leanbot commands to their respective functionalities:

Commands:

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

Functions:

  • Move forward.
  • Stop movement.
  • Close the grippers.
  • Open the grippers.
  • Rotate right.
LbGripper.open();
LbMotion.runLR(+400, -400); LbMotion.waitRotationDeg(90);
LbMotion.runLR(+400, +400);
LbMotion.stopAndWait();
LbGripper.close();

Question:

“The following commands are executed by Leanbot. Select all the correct actions performed:

  • Leanbot.begin();  
  • LbGripper.open();  
  • LbMotion.runLR(+400, -400);  LbMotion.waitRotationDeg(90);  
  • LbMotion.stopAndWait();  
  • LbMission.end();
