Mechanical Efficiency Winch Construction Guide Using VEX Robotics Platform

This guide outlines the step-by-step process to construct a mechanical efficiency winch using the VEX Robotics Platform and the VEX POE kit. It covers the assembly of a wire motor with clutch, motor mounts, and a drive shaft system. The instructions detail how to attach the winch cable with a specific knot, manage the power connections, and construct weights for testing the winch functionality. Perfect for educators and students interested in robotics and engineering principles, this guide provides a hands-on learning experience in mechanical design.
