1 INTRODUCTION & BACKGROUND

Opening a crown cap bottle can be challenging and even impossible for some people. Our team aimed to create a mechanism that could automate this motion, as well as pour the drink that was opened, in order to eliminate this challenge.

Bottle Cap Opening Schematic

This motion can be difficult because of the amount of torque that is needed to pop the bottle cap off. The input force needed depends entirely on the size and geometry of the bottle opener, as shown in the diagram below. Our ultimate goal is to use an appropriate combination of  actuators, links, sliders, and other mechanism components in order to safely and easily remove the crown cap and pour the drink.
