This step adds hardware to secure the SumoBot WX board to the chassis now, and also to hold QTI line sensors in the future.

Parts Required for each robot

• SumoBot WX PCB with FLiP module (not shown)
• SumoBot chassis, partly assembled (not shown)
• (4) Screws, 1-inch, 4-40
• (4) Aluminum spacers, 5/8 inch
• (2) 1/16" Nylon spacers
• (2) 1/8" Nylon spacers
• (4) 1 1/4-inch threaded standoffs

• Locate the SumoBot WX board’s front mounting holes.

• Thread a 1-inch screw through each of the SumoBot WX board’s front corners, from the top side.
• Slide a 5/8" aluminum spacer over each screw.
• Position the PCB over the chassis so that the front corners are over the front scoop mount, and the FLiP module is towards the back.
• Thread the screws through the front mounting holes in the chassis.
• Slide a  1/16" nylon washer over each screw.
• Tighten a 1 1/4" threaded aluminum standoff onto each screw.
• Repeat for the rear mounting holes, but using a 1/8" Nylon spacer.
