Preparing Lower Chassis
1
Adding front and side covers
Proceed to add front and side cover by following the link
https://nxp.gitbook.io/mr-b3rb/mr-b3rb-m-pre-production-mechanical-assembly-guide/step-1-preparing-lower-chassis.#adding-front-and-side-covers
2
Remove top plate screws and clips
Use a hex screwdriver or Allen Key and remove all top and side screws securing the top plate to the metal frame and carefully set them aside. These screws are important for later steps when you'll need to reattach the metal frame

Troubleshoot
For screwing of LED with the polycarbonate part , 13 mm size screws are used and Screwdriver with 0#+ number found in the buggy kit is used.
Use Screwdriver with 5.5 number for removing and attaching nylon lock nuts used as a spacer between the polycarbonate and the LED PCB.
Mounting the boards to the metal frame
We will now mount the NavQPlus and The MR-CANHUBK344 to the metal top plate.
1
Mounting the NavQPlus on the metal frame
Use the provided M3 screws to securely attach the board's corners to the metal frame

2
Mounting MR-CANHUBK344 and assembling into enclosure
MR-CANHUBK344 is the real time controller board for the robot. After successfully attaching the NavQPlus, the next step is to install the MR-CANHUBK344 evaluation board.

3
Assemble MR-CANHUB-ADAP to MR-CANHUBK344
ttach the MR-CANHUBK344 assembly to the top plate which already contains the NavQPlus board.

4
Assemble MR-CANHUBK344 onto top plate
MR-CANHUBK344 board should be attached with M3*5mm screws to screw it in the holes from bottom side

5
Mounting Standoff for LIDAR arch stability
Install the standoff which gives stability for later steps in the mounting of the robot. The screws are the ones that come with the purple standoff and the nut are size M3

6
Attach camera to front plastic mount
The camera housing included with the NavQPlus mounts to the front "GoPro" style mount on the front plastic

Troubleshoot
We need to take out the battery extender from NAVQ PLUS Box and connect it to the Battery Management System of the bot.
Use Screwdriver with H1.5 number to unscrew the screws from the NAVQ PLUS board.
Use Screwdriver with 2.5 number to unscrew the screws from the white plastic cover of the NAVQ PLUS board.
