How can a team ensure their robot stays within size and weight constraints?

• A. By painting the robot with light colors.
• B. By using the largest possible components.
• C. By careful design, measuring early, and maintaining a bill of materials.
• D. By ignoring the BOM.

Answer: (C)

Staying within size and weight limits comes from designing with constraints in mind, measuring early and often, and keeping a living record of every part. This approach lets you plan for the total footprint and mass from the start, and the bill of materials shows how each component contributes to weight and dimensions. With the BOM, you can sum up everything, see where there are margins or risks, and make informed choices or substitutions before building. That proactive tracking helps prevent surprises later and keeps the team aligned on what will fit. Painting the robot doesn’t affect size or weight, using the largest parts tends to push you over the limits, and skipping the BOM removes the clear snapshot of how every piece adds up, making it easy to miss constraints.
