Session 4: Assemble the Head Structure

In this session we will 3D-print the components for both arms while assembling the structural components of the gestureBot's head.

Parts:

  • servo labeled ID:001 programmed in Session 2
  • 130MM servo cable
  • (22) short plastic rivets
  • (5) long plastic rivets
  • (8) 3mm miniature steel screws
  • Neck 3D-printed in Session 3, the neck is connected to servo ID:002 that rotates horizontally allowing the gestureBot to turn its head and servo ID:001.
  • Head Swing Bracket 3D-printed in Session 3, the head swing bracket and servo wheel are attached to servo ID:001 that rotates vertically allowing the gestureBot to look up and down.
  • Servo Wheel 3D-printed in Session 3, the servo wheel supports servo ID:001 in the head swing bracket.
  • Head Frame 3D-printed in Session 3, the head frame attaches to the head swing bracket and provides a mount point for the speaker and face components.
  • Face 3D-printed in Session 3, the face connects to the head frame and provides a mount point for the speaker and the eyes.
  • Speaker 3D-printed in Session 3, the speaker is a mounting component intended as a placeholder for a speakspeaker modification in the future.

Tools:

  • PH0 Phillips screwdriver
  • plastic rivet tool

Session04 parts and tools

Procedure:

First, start 3D-printing the parts required for both arm assemblies:

Second, assemble the head structure:

  • Mount the neck to the horn () of servo ID:002, taking care to align the tick-marks of the servo cover, the horn, and the neck component. mount neck

  • Route the 130mm cable from servo ID:002 through the holes in the neck. route neck cable

  • Connect the 130mm cable to servo ID:001. connect neck cable

  • Mount servo ID:001 to neck with (4) rivets. mount head servo

  • Mount the speaker component and head frame to face with (4) M1 10mm machine screws. mount speaker to headframe mount headframe to face

  • Attach servo wheel to head swing bracket with long rivet. Do not install the rivet pin to allow the servo wheel to rotate freely. install headbracket servo wheel

  • Install servo ID:001 to head swing bracket taking care to align servo horn tick-mark with tick-mark on bracket. install headbracket servo screws

  • Mount face frame to head swing bracket with (4) long rivets. Installing the rivet pins is not recommended to accomodate future modifications and disassembly. mount face frame to head swing bracket

  • Inspect the gestureBot torso and head structure assemblies. torso and head structures completed
