AR Lesson 1 Review

Front

In a simple gear train with idler, which of the following statements is true? The driven gear is also referred to as the output. The middle gear is also referred to as the driving gear. The driving gear is also referred to as the output. The output gear is where the movement starts.

Back

The driven gear is also referred to as the output.

Front

Refer to the simple gear train set up below. The outer gears rotate in the ________ direction of the middle gear.

Back

opposite

Front

Your group wants to program a motor to drive forward for 2 seconds, stop for 1 second and then drive in the opposite direction for 4 seconds and stop. You create the following code. Will this code execute as you intended?

Back

Yes, this programming code meets all the requirements.

Front

Which of the following is an example of a scenario where a robot will move autonomously? A coding software program is used to create code and is downloaded to the robot, so that the robot moves based on the code. A coding software program is used to create code, and a person pushes the robot with their hands so that it moves faster. A coding software program is used to create code but is not downloaded to the robot. A person uses a handheld device to drive the robot, no coding software is used.

Back

A coding software program is used to create code and is downloaded to the robot, so that the robot moves based on the code.

Front

Which of the following must be true of the algorithm for Sophia and Jin's robot shuffle that lasts more than 20 seconds, goes both forward and backwards, and begins when BumperA is pressed? Options: The event handler block must include “When Brain left button is pressed”., The “wait time” of all the actions must add up to 15 seconds., The event handler must include a loop, The event handler block must include “When BumperA is pressed”.

Back

The event handler block must include “When BumperA is pressed”.

Front

What is the difference between a repeat loop and a forever loop?

Back

A repeat loop repeats for a designated number of times, whereas a forever loop repeats until the program stops running.

Front

Drew, Anaya, and Olivia are working together on a gear train. They want the output speed to be faster than the input speed. How should they assemble the gears to achieve this result?

Back

The driving gear needs to be larger than the driven gear.

Front

Describe the gear train that will meet the requirements for a drone propeller to spin at a speed of at least 400 rpm. You have a motor that spins at 200 rpm and the following materials: Gears in a variety of sizes. Options: There are 36 teeth on the input gear and 18 teeth on the output gear. The gear ratio of the driving gear and driven gear would be 1:1. The number of rotations of the driving gear equals 5 and the number of rotations of the driven gear equals 1. There are 18 teeth on the driving gear and 36 teeth on the driven gear.

Back

There are 36 teeth on the input gear and 18 teeth on the output gear.

Front

Your teacher says this is ok because you have failed forward. What do they mean?

Back

By learning what does not work with your design, you have learned how to improve on your next attempt.

Front

Which of the following is an example of someone not following the team norms?
1. Javier agrees to record everyone’s ideas as they share them with the group, one at a time.
2. As Bob is speaking, Bhavya has a great idea, but she waits until Bob is done before she shares it.
3. **James does not like the design that the rest of the group decides on, so he does not participate.**
4. **Desiree thinks that Harsha’s idea is great and tells him so.**
