Falcon Hand V2 by akarabian

This is a contribution to the eNABLE community of open-source prosthetic hands. The Falcon V2 is a new hand design for test of a number of new concepts. The key features we focused on for the falcon were: High degree of field maintainability: If a finger breaks, it is easily snapped off and a replacement is snapped on. Control cables are fished through one channel and crimped in place, requiring no tools and no knot tying. It is suggested that users are provided with 3-4 extra fingers with control cables run for easy repairs. Reduced (removed?) knot tying – ideally no knots are required for assembling a falcon hand (and by extension no knots to fail). Two position thumb: Allows for both key grip and cylindrical grip Modular Palm: The hand has a structural frame with a mostly cosmetic palm cover. If someone wishes to design a modified palm cover they simply need to match the hole pattern used for securing the palm cover to the palm frame. In doing so they can create artistic covers in any modeling software without having to deal with the structure or function of the hand itself. A sample palm cover is provided but improved ones are very much desired Rubber band return springs: To reduce build / assembly problems, dental rubber bands are used instead of elastic line for the return springs. These are easily available, cheap, and easily replaced should they fail. It removes the need for threading and knot tying of the elastic lines. Increased adjustability in proximal attachment: Since no knot is tied in the cable crimps they can be tweaked in and out and crimped and un-crimped until the right position is set. This is also key to item 1 (field maintainability) in that the user does not need to untie and retie with precision. Modular bracer (forearm part): A modular mount is provided on the bracer to allow for custom covering of the cable crimps. Preliminary designs have been proposed for picture frames, “ben ten” wrist communicators, watches, smart wearables, etc. Coming soon to a Falcon V2 near you (work still in progress) Locking system Modular palm designs Modular bracer covers Improved bearing surfaces on knuckle joints pins (covering the pins with cut-off bic pen barrels) Improved cosmetic appearance of fingers (cosmetic covers) Improved mounting scheme for palm cover Better scalability Improved printability (bridges) Your ideas here… For more information on where to connect with people who can help someone in need with sizing, printing and/or assembly a mechanical hand please join the e-NABLE Google+ Community entitled, e-NABLE:https://plus.google.com/communities/102497715636887179986 For more information and stories:http://enablingthefuture.orghttps://www.facebook.com/enableorganization SPU Design Team: Dr. Adam Arabian Barrett Estep Sean Russell Nicholas Rogers Parris Anawati This design is a product of the engineering department at Seattle Pacific University.
