Design and Assembly Instructions
The following tutorial outlines how to create a CAD assembly of a modified Straffer Chassis. In this case, the Chassis is modified so that the final bot dimensions are approximately 16"x16" so as to be well within the max size of the robot. (max size is 18"x18") The design is based off of the Version 4 Straffer chassis. https://www.gobilda.com/content/user_manuals/3209-0001-0004-v4.1-assembly-instructions.pdf

Chassis Sub Assembly.mp4Frame Assembly
Frame Assembly
Import the first set of parts into a sub assembly of the chassis. use the Joint Tool to connect the fram and build your sturcture.
Chassis Screws.mp4Adding Screws to the Frame
Adding Screws to the Frame
Add Screws to the frame to tie it all together. In some cases this can be extra work if you need to modify the layout, but it can also be helpful to identify interference zones.
Output Shaft Sub Assembly
Output Shaft Sub Assembly
In this section we will cad the output shaft for the wheel. This will be a sub assembly that is used four times in the full assembly. The tutorials cover updating the thrust bearing model first then assembling the output shaft.
