Introduction & Problem Statement

Introduction:

Pouring beer into a glass is a surprisingly delicate and complex task that requires careful balancing of many factors. Bartenders and brewmasters alike have various notions of a "proper pour", but what is universally important is a low foam-to-beer ratio that arises from a quick efficient pour following a distinct angular velocity profile. The naive solution of dumping a bottle of beer into a glass will cause the drink to vigorously foam up, and lead to very little liquid in the cup; this is what a standard pouring mechanism would result in. To overcome this challenge, we design a linear cam that mimics a bartender's expert pour.

Project Goals:

• Consistently pour beer without spillage of drink

• Entire bottle should be emptied in one pour

• Pour should result in minimal foam

• Pour motion should be smooth all the way through.

• Bottlecap should be opened
