We have evaluated several choices but we have no doubt that 3D printing is what we believe to best manufacturing technology for projects such as ours. We are very excited about what this technology is capable of and we want to believe in it now, as its strengths are in the geometric construction potential and the ability to optimize the price of single, unique, bespoke products.
The drawing clearly shows the movement system that we have implemented in the limb. This revolutionary mechanics is based on the material deformation, through the geometric control of the structure. We can manufacture the hand and all of its moving components in a single piece and with a single print.
For microprocessors (Arduino), servos and sensors we decided to use standard components, thus making our project more flexible and affordable to the final user. We were particularly impressed by the quality of these systems and we are more convinced than ever to continue down this path.
