  my name is Mahendra pitale.( MAHEN PITALE)     A graduate in fine arts from raheja school of fine art, mumbai (india)   worked with architecteral glass, also did abstract painting and participated in several group shows,  from last 5 years job in govt sector   and in spare time used to freelance for architects and interior designers,work with ngo’s,&   prosthetic awareness and i am involved in a program of prosthetic development with a lot of organization.  https://www.youtube.com/watch?v=_vQW62qphaA&t=6s friends, everything was going well in my life, after school, college, and then doing jobs, then got a chance to out of india  jobs, leaving home and working in other country had increased courage and enthusiasm, and i too was happy   and it was a day that i still cannot forget, i had to leave the office a little early from my office time, and i caught the train,  but there was a blast as soon as the 3rd station came, and i flew in the air, 5 minutes. after i

This Is the Most Amazing Biomimetic Anthropomorphic Robot Hand We've Ever Seen

First, they laser scanned a human skeleton hand, and then 3D-printed artificial bones to match, which allowed them to duplicate the unfixed joint axes that we have, as Xu explains: “For example, the motion of our opposable thumb is relying on the complicated shape of the trapezium bone located at the carpometacarpal (CMC) joint. Due to the irregular shape of the trapezium bone, the exact locations of CMC joint axes are not fixed. Thus, none of the existing anthropomorphic robotic hands can restore the natural thumb motions with conventional mechanical joints that require fixed rotation axes. We 3D print artificial bones from the laser-scanned model of a cadaver skeleton hand and connect them with artificial finger joints whose range of motion, stiffness, and dynamic behaviors are very close t

                 Science and technology are touching the sky in today's scenario. As the time passes technology has been used for the betterment of the human life as much as possible. Recent development leads various researchers in the field of biomedical and biotechnology engineering. Considering the current scenario this work is related with the design of a prosthetic hand for the amputee. It requires that a number of parameters should be considered but material selection is one of the key parameter in the design of the artificial hand. As the material selection directly affects the strength, weight and cost of the prosthetic hand. In present work stress analysis using ANSYS is performed for various materials and their comparative study is done. This work helps the design engineers as well as manufacturers to select better material with low cost, low weight and high strength. It is observed from the study that Nylon 6 can be used for prototype manufacturing of the prosthetic hand
