C channel c3x3.5 solidworks9/18/2023 ![]() The hardest part of the design was finding mechanisms that could make this motion. Here we document the overall story arc of how we arrived at our final design, offering this as a view of what was learned. Our work consisted of an unending stream of designs, prototypes, failures and changes. We felt that this represented the purest purpose of the assignment: inventing a mechanism, from scratch, to meet a desired objective. It is important to note that the decision for this shape of movement was made before any effort was made to research what mechanisms might achieve the movement, or even whether the movement was possible. It was felt that this was novel and did not have an obvious implementation. Based on early feedback from the Professor, we wanted to achieve this motion with a single motor. The movement that we settled on was described in our proposal with the following illustration: The brainstorming resulted in a plethora of options: Can be accomplished with a closed linkage.We brainstormed various paths that the lids of a box could follow, and filtered for ideas with the following characteristics: To achieve this, our team chose to explore complicated ways in which a simple box can open. The Final Project for Robot Mechanism Design was to apply the concepts learned in the class to a new mechanism and to physically construct this mechanism.
