What are "additional materials" in the context of rebuilding a robot?

In the context of rebuilding a robot, "additional materials" specifically refer to new components or materials not originally included in the robot's initial build. This term is significant because it highlights that while some parts of the robot may remain the same or be reused, the introduction of fresh materials can enhance functionality, improve performance, or address previous issues encountered in the original design.

This distinction ensures that builders can innovate and modify their robots effectively, potentially integrating advancements in technology or design that were not available or considered during the initial construction. Embracing new components contributes to continuous improvement and adaptation in the competitive environment of robotics.

While other options might suggest reusing or randomly selecting parts, "additional materials" emphasizes the potential for specific enhancements that are not just leftover or redundant components from prior projects.
