This is OneArm Module which would be plugged into modified version of eNable The Future Team
UnLimbited Arm and Phoenix Hand. The outcome would enhance the devices into simple bionic version inlow cost.
This project is a collaboration works between Hong Kong Maker Club and One Degree Production ServicesLtd for the DBS Social Innovators 2016. We have used 3D printed prosthetic devices (such as Team UnLimbited Arm and Phoenix Hand) to help Hong Kong children who born missing fingers or born an armwith an elbow but no wrist. All the current devices require the children to use their wrist or elbow to body drive for actions. Unfortunately, the children are born with very short palm or short residual forearm, theyare hard to drive these devices. Besides, we also received comments from their parents for requesting of electronic version of the 3D printed prosthetic devices. Finally, we designed the OneArm Module to fit their needs. We would like to start this project as an open source project and contribute to eNable The Future Community. Other people can contribute their works, finally, would enhance the devices to fit more children.
