<p><span class="warning">Safety first!</span> Wear eye protection and never touch a powered robot!</p>

35

<p>The purpose of this guide is to construct the chassis, attach the legs, and install the electronics. As long as the servo horns have not been removed from the servos, you do not have to center them during the assembly process.</p>

36

<p>Note: Two screws are included for attaching panels to servo horns. You may want to use four screws, as shown in some images. The 2-56 x 1/4" screws are available separately. Metal servo horns are an additional option.</p>

37

<p><b>Important! These instructions are for the robot's right legs. You will need to mirror these instructions and build three left legs as well.</b></p>

<div class="asm-step-name">Phoenix — Install SSC-32</div>

</div>

<p>Configure the SSC-32 for 115.2 kbaud and DB9 communication, with the VS2=VS1 jumper installed. Remove the VL=VS jumper. Consult the SSC-32 manual if needed. Attach the wiring harness to VS1. Connect 8" of 24AWG wire (not included) AND the 9V battery clip to VL to power the electronics. <span class="warning">Make sure red wires go to (+) and black wires go to (−).</span> Put electrical tape on the free wire end for now. Using four 4-40 x 3/8" hex socket screws, attach the 1.0" hex spacers to the board as shown.</p>

</div>

<p>Slip the SSC-32 in through the hole in the top of the robot and use four 4-40 x 3/8" hex socket screws to attach the board as shown. <b>Make sure the DB9 port is at the front of the robot, opposite the power switch hole!</b> This ensures you can easily plug in the servo cables. Install the power switch in the power switch hole at the rear of the robot.</p>

</div>

<p>Plug the servos into the SSC-32 as illustrated in Figure 12. Simply plug in the servo associated with the function to the corresponding pin. If oriented correctly, the I/O port (group of four pins) will be closest to its corresponding leg.</p>
