This is a 180° wrist mod for the Inmoov Robot
The wrist can have full movement without the fingers moving. The hand shown is made from ninjaflex.
The servo will have to be hacked to remove the potentiometer, in the same manner as some of the other servos in the robot. Don't forget to remove the pin on the potentiometer gear inside the servo.
The servo has to be attached with 3 screws, not 4 as the 4th will interfere with the potentiometer. It's self explanatory when installing the servo.
I am using the EZ-Robot HDD digital servo, strong and quiet. http://www.ez-robot.com/Shop/AccessoriesDetails.aspx?prevCat=9&productNumber=7
The Pot Gear needs a bearing >>Ball Bearing 625 2RS 5x16x5. If you have any openbuilds v wheels or idler wheel, theses are the ones used.
There is an STL showing the parts assembled.
Please ask if you have a question.
ABS is probably the best material to use.
