Alien Hand
Description
This Is What You Might Call A *De*-Ssistive Device - It Takes Two Perfectly Good Hands To Operate One Rather Feeble (Although Slightly Sinister) One. Inspired By Various Tentacle Designs (Http://Www.Thingiverse.Com/Thing:6986, Http://Www.Thingiverse.Com/Thing:10337, Http://Www.Thingiverse.Com/Thing:206231), Each Finger Prints As A Single Piece With 12 Flexible Sections And Can Be Configured In 8,388,608 (Give Or Take) Different Ways. I'Ve Got This Version Configured As Two 4-Dof (Degree Of Freedom) Fingers And One 2-Dof Thumb. You Can Actuate Particular Flexures In A Finger By Running The Tendons Through Holes In The Outside Corners, And Not Activate Other Flexures By Running The Tendons Through Holes In The Center. I'Ve Biased All Three Fingers Backwards With Tendons Running Along The Back Side, And That Are Then Attached To Rubber Bands. And Finally, I'Ve Mounted The Fingers On A Palm-Gripped Platform That Lets You Use All 10 Of Your Fingers To Operate All 10 Degrees Of Freedoms. As You Can See From The Video (Https://Youtu.Be/Ws8D-Ch5Kbk), Though, Moving The Fingers Gracefully Will Take A Bit Of Practice! I'M Hoping Some Clever Soul Will Print Their Own And Hook It Up To Rack Of Rc Servos.
