FTC Rigid Claw

This is a gripper well suited to pick up blocks for FTC Freight Frenzy. This evolved from the flexible grippers in my Thingiverse account.

This is designed to be used with a standard servo. The servo is installed into the motor mount and spool is used to spin wire cables to close the claw, springs are installed to open the claw when the servo spins to open position. Note adjustment screws on spool allow adjusting tension on each claw separately, similar to adjusting guitar strings. Once set epoxy in place, I also place epoxy on wire going into spool hole. Designed for FTC legal servo. Stainless steel cable is used and standard cable crimp sleeves. I used AHANDMAKER 304 Stainless Steel Wire Cable with aluminum crimp sleeve from Amazon.

Crimps are used at each end of cable for each claw. Screws are adjust and match tension on all four fingers of gripper which was difficult to do with
