Have you ever observed a busy bar counter where the bartenders not only need to interact with customers while preparing various cocktails but also have to open a bunch of cans manually in a short time? Have you ever experienced the inconvenience of a hand or finger injury/trauma that made the can-opening task became suddenly hard? Whether Do you or your friends always want to keep good condition of your vulnerable nails? The tiny can-open task is kind of bothering opening task can be bothering or inconvenient in many cases. To solve this, the automated robotic can-opener of our project with a specific linkage mechanism design is aiming to economize aims to eliminate manpower and make our lives much easier when dealing with these dilemma conditions.!
Problem Statement
Many currently used automated can openers require user input to open a can. We need a can-opener mechanism that will autonomlously locate the tab of a can and to open it with adequate force. The complexity of our design stems from determining the correct link lengths, angles, and force such that the mechanism's 'end-effector' motion of our mechanism will consistently translate and rotate to pull the tab of the can open. The use of simple joints is not suitbale to accomplish this task because we need our linkages to that have enough compliance to achieve desired angles while maintaining structural integrity to lift the tab and open the can.
...
We have utilized MotionGen to mock up a few potential 8-bar geometries that could generate the position profile that would scoop under the tab and push it upward. In addition to this 8-bar, the end effector link would have a tip that can be pushed back when the link meets the top of the can, and as the link meets the tab the interaction locks the tip into place.
