Review - Automation and Robotics

Refer to the simple gear train setup in the photo.

• There are two input gears and one output gear.

• There are one input gear, one idler gear, and two output gears.

• There are one input gear and two output gears.

• There are two idler gears and one output gear.

How is a build guide a useful communication tool for engineers?

• It tells the robot exactly what to do, saving you time.

• It provides clear step-by-step instructions to help you assemble parts successfully.

• It builds the product for you so that it is done correctly.

• It provides several different build options so that everyone in the class has a different final system, some of which will not work.

What is one benefit of adding a loop to an algorithm?

• If you need to edit the code where the loop occurs, you will need to update the code in several places.

• Adding a loop will require you to write the same set of code multiple times.

• By adding a loop, the algorithm will always run only once and then automatically stop.

• Using a loop will reduce the number of steps and time you spend writing and editing the code.

Davonte, Emma, and Aleks are working together to create an algorithm for their robot with the following design requirements: The robot must move forward and backward, the code must include a loop, the code must include a wait or pause, and the code must continue to repeat for as long as the program is running. They came up with the code shown in the diagram, but it isn’t successful. How can the group debug their algorithm to meet the design requirements?

• They need to replace the repeat loop with a wait loop.

• It is coded correctly; they should check their hardware connections.

• They need to replace the repeat loop with a forever loop.

• They need to replace the repeat loop with a drive loop.

According to the table, which of the following statements is true?

• In Setup 1, the driving gear is larger than the driven gear.

• In Setup 2, the output gear is larger than the input gear.

• In Setup 1, the driven gear is larger than the driving gear.

• In Setup 2, the driven gear is larger than the driving gear.

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?

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

• The driving gear and driven gear need to be the same size.

• The output gear needs to be larger than the input gear.

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

Which of the following statements is true?

• When designing a solution to a problem, there is only one correct way to do it.

• If a client is hiring you for a project, it is ok not to follow all the client’s design requirements.

• You should always document your sketches and ideas in your PLTW Gateway Notebook.

• You must fail before you can make any improvements to your design.

Why is it important to repeatedly test your design as you are building it?

• To troubleshoot any problems that may occur.

• To ensure that it meets the design requirements.

• To try out different improvements to the design.

• All of the above answers are correct

After learning how to create algorithms, you realize you have a strong interest in learning more about creating programs in high school to determine whether the skill could be a possible career path for you. What types of classes would help you specifically learn more about coding?

• Mechanical engineering: develops mechanical systems and technology to meet the needs of humans and other living creatures.

• Software development: designs, builds, and maintains computer programs, like the ones on your computer, phone, and gaming systems.

• Electrical engineering: focuses on the design, development, and maintenance of nearly everything that uses electricity.

• Aerospace engineering: develops technologies for use in aviation, defense systems, and spacecraft.
