Preparing the Level One Chassis

Start 

This is the Third Project in the Robotics Series. In this kit we'll be adding on a second level to your completed Robotics Kit 1. Before we can do that we must disassemble some of the first kit. There is a hole in the chassis were a pen, pencil, or marker must pass through. That hole is right below the I2C Motor Driver. The bad news is we have to remove the I2C Motor Drive to make room for the marker. The good news is that the level two chassis has more room and that's where we'll be attaching the driver.

Modules 

Gather the following parts to complete this project.

Remove Cable to the I2C Motor Driver 

Take the cable out of the I2C Motor Driver and its other side in the black base shield. You leave any cables going to the line finders or the WiFi module.

Unscrew Terminals 

Unscrew the six screws found in the green terminal blocks of the I2C motor driver. The screws will not and should not come out of the terminal blocks. Remove all wires from the terminal blocks. This includes two coming from the battery holder, two from motor one, and two from motor two.

Unscrew the I2c Motor Driver 

Unscrew the two M2 10mm screws holding the I2C motor driver in place. You will need to hold the nut on the other side as you undo the screws. With the screws removed, take off the I2C motor driver.

Combining the Standoffs 

Take all eight 20mm standoffs from the hardware bag. Using two as a time, combine them to create one 40mm. Repeat this three more times until you have a total of four 40mm standoffs.

Attaching the Standoffs 

Place one of your newly made 40mm standoffs in one of the holes shown below. Attach and hand tighten a nut to the bottom of the chassis where the standoff pokes through. Repeat this three more times in the remaining holes.
