$3.25Robotic Finger prototype

myminifactory

This is a 3D printed prototype of a finger with 3 joint for the LAD Robotic hand as shown on the photo and on the video above.  The design was made to be printed on a SLS 3D machine. However, each link can be printed in a FDM machine with the right supports and some post-processing.  I glued the finger to a plastic box (not included in files) for display. I used three  M3 bolts and nuts (18mm, 22mm and 25mm long) to join each phalanx together, and four  headless nails 1~ 1.25mm in diameter  as pins for the two connecting rods (9mm long x 2  for the short rod, and 5mm long and 22mm long for the long proximal rod ).     Get to know the LAD Robotic Hand below.   Was a very interesting project. See how the LAD hand was made.
