This project shows an alternative for prosthetic terminal devices. It´s objective is be able to grasp cylindrical objects up to 70 mm of diameter. During the design of this terminal device, different variables were consider, such as be modular, anthropomorphic, ecofriendly (less material and energy use for production) and the ability to be 3D printed in different plastic materials like PLA (Polylactic acid), ABS (Acrylonitrile butadiene styrene) and PET (Polyethylene terephthalate). The scope of this project explores the usage of hydraulics and solid structures capable of move without changing its original shape. As a result it’s presented a design of a terminal device that base itself on the idea of an affordable prosthetic with applicable functionality.
