About Us

M1 is a group of Cal Poly students, mostly made up of engineering and architecture students. These students are working on making an affordable, yet fully functioning prosthetic arm. Thanks for checking M1 out!

Here is Weston Cramer putting the final mechanical touches on our first prosthetic hand:

Sunday, October 8th, the final mechanical touches are put on the M1 prosthetic hand in the Mechanical Engineering building at California Polytechnic State University. The Mechanical Engineering Building at Cal Poly has a project room that is the perfect place for the 25 students of the M1 Prosthetics Club to build their hand. On Sunday, October 8th, 3rd year Industrial Engineering major, Weston Cramer, puts in one of the main motors of the prosthetic hand saying, “This hand is different, it’s more similar to a car or a house than something like a phone, because it needs to be lived in and used everyday.” The hand’s main shell is made from a system called Selective Laser Sintering with Nylon material, the layers are visible to the human eye. However, after the design team gets a hold of the hand – headed by 3rd year Architecture major, Giannine Escobar – the hand will have a makeover. In a designated room, all the parts are laid out so that Cramer can put the finishing touches before the design team works their magic. Cramer is attaching the device that will give the hand it’s strength to grip something about the size and weight of a can of soda, while still having the dexterity to tie a shoelace. After attaching the final finger together, Cramer displays the full range of motion from fully extended to making a fist. The index finger is also displaying the “pinch-feature” which allows for the dexterity of the hand. After about 3 hours of working on building the hand, at 9:32 P.M on October 8th, 2017, Weston Cramer has finished the inner mechanics of the soon-to-be fully functioning hand. “This hand is unlike anything else on the market right now, it is a lot cheaper to manufacture...” Cramer says, “We want to go the extra mile to change peoples lives for the better.”
