CAD Model and Drivetrain Building Quiz Onshape Level 3

Why is building a drivetrain from a CAD model beneficial?

• It helps in learning CAD by examining the model closely

• It allows skipping over CAD and focusing on building

• It is a faster way to build a drivetrain

• It is not beneficial for robotics

What is the advantage of starting with a simple established design?

• It allows for critical building techniques to be learned

• It saves time in the long run

• It eliminates the need for CAD

• It restricts creativity in robot design

Which drivetrain is used as an example in the CAD model?

• Basic Four Motor Chassis

• Advanced Gear Drivetrain

• Complex Chain Drivetrain

• Intake-only Drivetrain

What is the purpose of the bill of materials in the CAD model?

• To list all the parts needed for building the drivetrain

• To provide step-by-step instructions for building

• To show the order of assembly for the drivetrain

• To explain the functionality of the drivetrain

Why is it recommended to use shoulder screws for structural support?

• They provide a tighter connection and prevent racking

• They are easier to tighten than regular screws

• They are cheaper than regular screws

• They are more readily available in hardware stores

What is the purpose of the spin test for the drivetrain?

• To check if the wheels roll freely

• To test the speed of the drivetrain

• To measure the torque of the motors

• To ensure the shaft collars are tightened properly

What should be done if a wheel fails the spin test?

• Check for too many spacers jamming the wheel

• Replace the motor connected to the wheel

• Tighten the shaft collars on the wheel

• Increase the voltage to the motors

What is the purpose of the inside rail in the drivetrain?

• To provide support for the motors

• To connect the chassis to the wheels

• To hold the electronics of the drivetrain

• To prevent the wheels from spinning freely

What is the purpose of the front and back support in the chassis?

• To provide additional stability and prevent racking

• To hold the wheels in place

• To connect the chassis to the electronics

• To increase the speed of the drivetrain

What is the purpose of the outer rails in the drivetrain?

• To hold the wheels in place and provide support

• To connect the chassis to the electronics

• To increase the speed of the drivetrain

• To prevent the wheels from spinning freely
