Getting going

SpotMicroAI

Building the legs

  1. The leg consists of five parts, the foot, the forearm, the mid-arm, the mid-arm cover, and the upper-arm (See picture below). Print these for each of the four legs. (don't forget to flip the parts for the opposite side). The parts are shown in the orientation that I printed them, I've found this orientation yeilds favorable results. SpotMicroAI

  2. Remove Supports SpotMicroAI

  3. Grab the Foot and the Forearm and then SpotMicroAI Test fit them and remove any irregularies the get in the way. SpotMicroAI Glue them together either with hot glue or CA glue. SpotMicroAI Repeat for the remaining legs.

  4. Grab a servo for each of the forearms as well as two mounting screws. SpotMicroAI Insert the servo with the nub facing away from the foot. Insert the screws into two of the mounting holes. SpotMicroAI Repeat for the remaining legs. SpotMicroAI

  5. Grad the midarm and a servo horn. SpotMicroAI Cut the servo horn at the second hole. Test fit the servo horn into the spot for it. SpotMicroAI Glue using either hot glue or CA glue being careful not to get any glue in the space where the horn mates with the servo and repeat for the remaining legs. SpotMicroAI

  6. Grab the mid-leg covers and a 5mm bearing. SpotMicroAI Place the bearing in the recess and drip a few drops of CA glue around the edges where the bearing meets the plastic, being careful not to get any glue on the inner part. Repeat for remaining mid-leg covers. SpotMicroAI

  7. Grab the completed foreleg, the completed mid-leg, the completed mid-leg cover, one servo horn screw and one 3M 12mm threadcutting screw SpotMicroAI Attach the completed mid-leg to the completed foreleg via the servo horn. Be sure that the servo's end position matches with the point at which the leg is most flexed. SpotMicroAI Test several times to be sure the servo is in the correct orientation. When you are satisfied it is, screw in the servo horn. SpotMicroAI Loosly fit the mid-arm cover over the mid-arm, thread the servo wire through the small passage leading up the leg. SpotMicroAI Open the leg. SpotMicroAI Insert the screw into it's receptacle on the back of the leg SpotMicroAI Grab a servo and mounting screws SpotMicroAI Insert the servo into it's home with the servo lead pointing towards the foot SpotMicroAI Insert the mounting screws to secure the servo in place SpotMicroAI Repeat for the remaining legs SpotMicroAI

  8. Grab an segment of upper arm, a two armed servo horn, and some cutters. Cut the servo horn at the second hole on both sides. SpotMicroAI Test fit the servo horn. When comfortable with its fit glue into place using a generous amount of glue. SpotMicroAI Repeat for the remaining upper-arms SpotMicroAI

  9. Grab upper arm and completed lower leg. SpotMicroAI Test fit the upper leg onto the rest of the leg, ensure proper range of motion SpotMicroAI SpotMicroAI SpotMicroAI When comfortable with range of motion, screw the servo horn in place. SpotMicroAI

  10. Grab a servo and mounting screws SpotMicroAI Place the servo with the horn facing away from the foot (same end as the nub in the plastic) SpotMicroAI Insert the mounting screws SpotMicroAI
