Summary
We plan to create a mechanism that can replicate the shaking motion used by bartenders to mix drinks in a cocktail shaker. This will require a combination of mechanisms as the motion is a combination of translational and rotational movement. We must control the speed of the shaker at different points and ensure it only shakes for a maximum of 15 seconds. Any more time than that will result in over-mixing, which can ruin the drink. The video below shows the motion we are trying to replicate.

Our problem is to design a mechanism that replicates the action of shaking a cocktail shaker with proper bartending technique. The complexity of the cocktail shaking technique comes from the ‘V’ shaped motion profile created. This profile is composed of a repetitive translational motion and the periodic change of the shaker angle to a horizontal position. These motions together make the solution too complex for only simple joints and will require more mechanisms.
Our team combined a Peaucellier-Lipkin linkage, which transforms rotational motion into a straight line, and a CAM, which rotates our linkage to create an angle change to create the desired motion.
