Intro to Robotics Assessment

What happens when condition in "repeat untill" block evaluates to "true"?

• The robot ends the program.

• The robot continues to repeat the loop.

• The robot skips all the blocks in the loop and moves on in the program.

• The robot executes the block within the loop but skips rest of the program.

A robot completes tasks in a random order.

• True

• False

Program flow is referred to as......

• the way a robot executes a program from top-to-bottom.

• the way a robot executes a program from bottom-to-top.

• the way a robot executes a program by alphabatical order.

• the way a robot executes a program in a random order.

A "wait until" block.....

• holds program flow in that place.

• needs a true condition to proceed in program flow.

• helps a robot make a decision.

• All of the above.

The ................ sensor sends sound waves by the emitter to bounce of an object and come back to the receiver.

• distance Sensor

• force Sensor

• color Sensor

• gyro Sensor

Placing an "if-then-else" block inside a loop is a common technique often used to......

• Repeat a sequence of movements in exactly the same way many times.

• Choose between two branches of code.

• Repeat a decision multiple times.

• none of the above.

What will the robot do if it does not sense an object within 20 cm?

• Display smilie

• Turn right

• Play beep

• Move forward for 15cm

Why would this program not work when trying to detect obstacles?

• Movement block prevents the sensor to be checked at the right distance.

• The distance sensor is unable to detect, anything at that distance.

• The "wait-until" block should be placed above the movement block.

• All of the above

What happens in Program Flow when a condition in a “repeat until” block becomes true?

• The robot ends the program immediately.

• The robot continues to repeat the loop.

• The robot skips all the blocks in the loop and moves on in the program.

• The robot executes the block within the loop but skips rest of the program.

Which of the following is NOT true about the condition in a loop?

• It can repeat blocks forever

• It can be set to run the commands in reverse

• A sensor can be used to decide whether to repeat or move on

• Any positive integer can be used to repeat a certain number of times
