Prosthetic Hand for designers to experience

thingiverse

The Innovative MeRP 2.0 Research System is a custom-designed wrist-activated prosthetic hand tailored for use by individuals who don't need prosthetics, yet seek to incorporate them into their daily lives. This breakthrough technology enables prosthetic designers to refine their designs firsthand, allowing them to truly understand the needs and preferences of users. By leveraging real-world feedback from those who will ultimately employ their products, designers can hone in on the exact features and functionalities required to optimize user experience. The MeRP 2.0 attaches snugly to the forearm via a secure gauntlet that cradles the prosthetic hand, allowing it to function seamlessly beneath the wearer's own hand. Wrist movements activate the prosthetic fingers, causing them to articulate in precise grasping motions due to a network of delicate strings simulating tendons within the hand. The MeRP 2.0's adaptable framework empowers users to experiment with an array of distinct prosthetic hands, fingers, thumbs, gauntlets, and actuation systems – providing instant feedback on the merits and drawbacks of each configuration. By exploring different permutations, individuals can pinpoint optimal design combinations that cater specifically to their unique needs.

Recognition: MeRP 2.0 owes its existence to a masterful fusion of the open-source designs provided by https://www.youmagine.com/designs/rit-e-nable-arm-v0-44#!design-information, as well as cutting-edge innovations devised by the brilliant e-NABLE volunteers based at Rochester Institute of Technology. Crafting Essentials: When linking the Gauntlet to the Hand, ensure secure fastening with 1/8 inch carbon fiber rod: https://www.amazon.com/Carbon-Fiber-Rod-40-125/dp/B000BRFWOG/ref=pd_sim_t_3?ie=UTF8&refRID=02Y5NFA0MS6MCVFBWH12 (avoid purchases made from Chinese vendors to avoid long wait times). For efficient printing, flat print the Gauntlet halves using PLA at a hotbed temperature of 90C. Mold and fold while still warm around a pre-prepared shape. Reinforcement is crucial; fabricate hinge pins with 1/8 inch filament and reinforce their ends by melting them over with a soldering iron. You can source packs of affordable 3mm filament at https://3doodler.com/, ensuring seamless integration on your printer's standard 1.75mm bed. Create grasping bars from available stock 3mm filament, employing a heat gun to mold and bend desired shapes while solidifying with an adjacent flame. Pinching points must then be securely sealed with melted material via iron. Connect thumb modules onto palm assemblies using fabricated 1/8 inch filament fasteners for smooth interaction between prosthetic parts.
