32 - <p><b>Hardware:</b> 3x Multi-Purpose Servo Bracket Two Pack (ASB-04) · 1x "L" Connector Bracket Two Pack (ASB-06) · 1x "C" Servo Bracket w/ Ball Bearings Two Pack (ASB-09) · 1x Offset Servo Bracket w/ Ball Bearings Two Pack (ASB-11) · 1x Aluminum Tubing Connector Hub pair (HUB-08) · 2x Aluminum Tubing 3.0" (AT-02) · 1x Rubber End Cap .500" x 1.50" Pair (REC-06) · 6x HS-5645 Digital Standard Servo (S5645MG)</p>
33 - <p><b>Goal:</b> Assemble a pair of humanoid biped arms using servo brackets, aluminum tubing, and a Little Grip.</p>
34 - <p><b>Notes:</b> This guide covers one arm for the robot's right side. Repeat all steps as a mirror image for the left side. This is only an example — there are countless other configurations with fewer degrees of freedom, no tubing, etc.</p>
