After being denied a full prosthetic hand by his health insurer, Instructables user tankapotamus came up with an inexpensive replacement by making a robotic claw "hand" that is fitted to the end of his prosthetic arm.
By adding a strong servo to an inexpensive claw mechanism that can be found from various retailers, the claw could then be controlled by an Arduino and the user has fitted a rotary encoder that can be used to adjust the claw. This is demonstrated in the following video:
Kudos to the creator for coming up with a practical solution for an unfortunate problem. For more details and information, check out the project page. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.
If you're looking to learn how to use an Arduino with sensors, servos, LCDs and much more - you can't go past reading a copy of "Arduino Workshop - A Hands-On Introduction with 65 Projects” by John Boxall.
Arduino Workshop takes the reader from having zero knowledge about the Arduino platform, electronics and programming and leaves them with the know-how and instructions on everything from blinking an LED, to robotics, wireless data, cellular communications, motor control, sensors, Internet connected systems and more. For more information including a sample chapter and table of contents, visit the book page.
