3D Printed Underactuated Hand

grabcad

In Olin's Mech Proto class, we created an underactuated hand almost entirely via 3D printing. Underactuated hands use fewer motors than joints, relying on intelligent design for movement; ours had one motor controlling six joints. The hand can grip irregular objects with just a single actuator, based on previous designs. I focused on the wrist design, with fun renders to showcase it. A PDF report attached details our reflections on the project, completed alongside Alex Spies, Daniel Dichter, and Kory Kautz. ### Another Response: At Olin College's Mech Proto class, we designed and constructed an underactuated hand, mainly using 3D printing technology. Underactuated designs have fewer motors than joints, utilizing smart mechanical engineering for motion control; our hand featured one motor controlling six joints and was able to grasp irregular objects with a single actuator due to its innovative design. I concentrated on the wrist portion, creating renders for added visual appeal. Our experiences and thoughts on this project are documented in the attached PDF report, which was collaboratively done with Alex Spies, Daniel Dichter, and Kory Kautz.
