The Dextrus hand is a robotic hand that can be put together for well under £650 ($1000) and offers much of the functionality of a human hand. Existing prosthetic hands are magnificent devices, capable of providing a large amount of dexterity using a simple control system. The problem is that they cost somewhere between £7,000-£70,000 ($11,000-$110,000) — far too much for most people to afford, especially in developing countries. Through the Open Hand Project, an open source project with the goal of making robotic prosthetic hands more accessible to amputees, a fully-functional prototype has already been developed. An indiegogo campaign is currently underway to provide funds for refining and testing the design.
