Why might a bumper switch be less effective than a limit switch in certain situations?

• The bumper switch cannot detect objects at an angle or with light force

• The bumper switch requires more programming than a limit switch

• The bumper switch cannot detect objects at all

• The bumper switch is too sensitive to all forms of pressure

Which switch would you use if you needed to detect objects approaching at an angle with minimal force?

• Limit switch

• Bumper switch

• Both switches are equally effective

• Neither switch would work

Why might a programmer choose to use a bumper switch instead of a limit switch in their design?

• The bumper switch is more reliable with direct, strong forces, such as a button press

• The bumper switch is designed to detect slight, indirect pressure from any direction

• The bumper switch can detect objects without making contact

• The bumper switch requires less programming knowledge

In which scenario would a limit switch be more effective than a bumper switch?

• When detecting an object that brushes against the robot lightly

• When requiring a strong force to activate the switch, such as a button press

• When needing a switch that remains pressed even after the object moves away

• When detecting sound in the environment

What is the primary difference between a limit switch and a bumper switch?

• A limit switch is more sensitive and can detect light touches, while a bumper switch works best with direct force

• A bumper switch is more sensitive to small movements, while a limit switch requires firm pressure to activate

• A limit switch is used only for detecting walls, while a bumper switch can detect any object in its path

• A bumper switch can detect objects at a distance, while a limit switch requires physical contact to function

What would a programmer not need to do if they use loops instead of copying and pasting code?

• Write the same code repeatedly

• Test the code for errors

• Think about the logic of the program

• Set up the initial program

What is one of the main benefits of using loops in algorithms?

• Loops reduce the amount of repetitive code a programmer has to write

• Loops allow a program to run only once before stopping, making it more efficient

• Loops eliminate the need for debugging the code

• Loops allow the program to run in multiple directions

What is a disadvantage of copying and pasting code instead of using a loop?

• The programmer will have to update every copy of the original code if changes are needed

• Copying and pasting code makes the program run faster but increases the chance of syntax errors

• Using copied code instead of loops allows the program to use less memory and run more efficiently

• The loop might stop working

Why is it easier to update code that uses a loop compared to code that copies and pastes the same commands?

• The programmer only needs to update the loop once in a single location

• The loop automatically updates itself without any changes needed by the programmer

• Loops can rewrite the entire program automatically

• Using a loop prevents the need for any debugging or modifications in the future

How do loops help a programmer reduce the time spent writing code?  

points

• Loops allow the programmer to write the code once and repeat it without copying and pasting

• Loops automatically generate new code for every repeated action without programmer input

• Loops run the code faster than other commands

• Loops automatically correct errors in the program
