Terminator Online Assembly Instructions, Revision 2.

Safety first! Wear eye protection and never touch a powered robot!

Chassis Assembly
Step 1. Install the aluminum bars to the left side panel as shown  Use 6 of the 4-40 x 3/8 screws for each side as shown; make them go through the lexan first, then the aluminum bar. Install 4 of the 4-40 x 5/8 screws from the inside; they'll go in through the aluminum bar first, then the lexan. Make a mirror image for the right side.

Note: Do not use thread lock as it may damage the plastic.

Step 2. Install 4 of the 1-1/2" spacers onto the 4-40 x 5/8 screws that were installed in the previous step. Tighten them down till the flat side is lined up with the panel and aluminum bar as shown in figure 2. Mirror for the right side.

Step 4. Solder the cap across the terminals as shown. Make sure you put the red to (+) and the black to (-). This will make wiring the speed controllers easier later on. Use at least 20 awg stranded wire and cut to a length of about 6".

This completes the assembly of the rolling chassis. Now you need to add your own scoop, motor drivers, sensors and microcontroller. It is still a long way from being battle ready, but it's a great start!
