U5L2: Using Comparison Blocks and Driving Until Near

Which of the following blocks is a Boolean block that reports if the first value is larger than the second value?

• <Less than> block.

• b. <Greater than> block.

• (Random) block.

• <And> block.

Which of the following blocks is a Boolean block that reports if the first value is less than the second value?

• (Round) block.

• <Or> block.

• <Greater than> block.

• <Less than> block.

What value does a block report while inside of a [Wait until] block?

• The distance to the nearest object.

• A TRUE or FALSE value.

• The total time needed to run the project.

• The total time the VR Robot has until it reaches an object.

Which of the following describes that the VR Robot will drive forward until the value of the Distance Sensor is less than 150 millimeters (mm)?

• Drive forward for 150 millimeters (mm).

• Drive forward until the Distance Sensor is greater than 150 millimeters (mm) away from an object.

• Drive forward until the Distance Sensor is less than 150 millimeters (mm) away from an object.

• Drive forward, stop, drive forward again for 150 millimeters (mm).

Why was the [Drive] block used instead of the [Drive for] block in this project?

• If the [Drive for] block was used, the VR Robot would drive a specific distance and come to a stop before moving to the [Wait until] block. This is because the [Drive for] block is a waiting block and does not allow the project flow to continue until its condition is met.

• If the [Drive for] block was used, the VR Robot would start driving until it was told otherwise. This is because the [Drive for] block is a non-waiting block and will allow the project to move to the next block in the stack immediately.

• If the [Drive for] block was used, the VR Robot would drive a specific distance four times, acting as a [Repeat] block.

• If the [Drive for] block was used, the VR Robot would not move. This is because the [Drive for] block is a reporter block.
