Carpe Mundum – Seize the World!
Additional hardware needed for this project!
Carpe Mundum is a system designed for quadriplegic individuals who have retained gross arm movement but have lost the use of their fingers. The goal of the device is to help pick up various objects off the floor, including small items like coins and pens, flat items like cell phones, tablets, and books, and oddly shaped items like toys, cups, silverware, clothes, etc. The system includes different tool heads depending on the required task. Items up to a few pounds can also be picked up with some of the tool heads.
The files for the system can be found here: https://www.printables.com/model/1383636-carpe-mundum-grabbergripper
Model description
The pincher grabber is another tool head for the system. This current design is a remix of an existing grabbing tool, and I've loaded it as a separate model so I can properly attribute it. I plan to design a better functioning pincher grabber in the future. This grabber is composed of two semi-circle fingers that pinch toward each other to grip, wrap around, or hook onto an item. This gripper is useful for picking up items with handles like mugs or jugs, wrapping around wide cylinders like cups, or picking up lightweight soft items like clothes or small stuffed animals.
