Servo Hand - Raptor Reloaded Rework

thingiverse

This is one of the two hands we developed, the Servo Hand. It has a set of servos controlled by a Myo armband. Parts still needed [Obtain the files from Raptor Reloaded]: Wrist Pin Wrist Pin Cap Thumb Pin Knuckle Pin Finger Pin Gauntlet Retention Clip Fingertip (alternatively, print the two remakes we made: thing:1179988 and thing:1182856) Proximal These parts are compatible with the Raptor Reloaded and scales with the Raptor Reloaded. NOTE: The Arduino casing is NOT to be scaled. Print Settings Rafts: Doesn't Matter Supports: Yes Infill: 25%[palm]; 40%[spool] Notes: 3-4 shells for the remodelled palm, 4 shells for the spool. For better details for the spool, print the outlines at a lower speed. A good cooling system should allow the spool to print out well. Post-Printing First, use epoxy or contact glue to attach the Arduino mount and the case together. Then, just assemble it on the gauntlet with the retention clip to keep it in place, similar to how the tensioning block in the normal Raptor Reloaded is attached. As for rigging up the servos, first cut off the servo arm so that it can fit into the spool, then screw it on. Put the servo into the slots according to the photo above. The elastic thread is to be threaded just like the normal Raptor Reloaded. The fishing line, however, is to be threaded through the spool. The bottom servo is for the thumb, the top servo closest to the thumb is for the forefinger, and the last three servos connects to the remaining finger.
