Main robotisée Exiii Hackberry (pouce-index)

thingiverse

This project is derived from the HACKberry project originated by exiii Inc. Exiii Hackberry: a source open hand prosthesis printed in 3D. Prosthetics allow for missing limbs to be replaced, but they have several drawbacks: their cost (between $8,000 and $10,000) as well as the need for maintenance and the fragility of the device. In Japan, exiii offers an alternative, a source open hand prosthesis printed in 3D. Here it is in video. In order to make prosthetics accessible to all, exiii, a Japanese company, has developed a source open hand prosthesis entirely printed in 3D called Exiii Hackberry. The cost of fabrication is only $200 (179 euros at the current rate). At first glance, it may seem quite simple, but with its three servomotors, it is already possible to open and close the hand or grasp objects. The system is controlled by a small sensor placed on the arm that activates when a muscle contracts. This prototype currently has a lifespan of one day and functions with an Arduino. exiii hopes that with its source status, this prosthesis will be rapidly perfected and personalized by users. This fairly complex hand was realized in the form of a didactic model. Here is a link to a video describing it: https://vimeo.com/223029018 With the consent of Japanese company exiii, the files allow for printing the pieces of this model's thumb and index finger. The functioning of this model: https://vimeo.com/255171783 These models are used in the context of technology courses in high school.
