### Background

* This is a custom spin-off of the OSR V2 design, utilizing mostly the same electronics and software stack, but made out of a combination of laser cut aluminum and 3D printing technologies such as MJF, SLA, and SLS. It was inspired by my partner who asked for a ring bearer robot at our wedding, and this project was particularly special to us as I was working on designing the very first Open Source Rover at JPL when we met.

### Modifications

<table>
<tr>
<td width="50%">
Custom channels, creating the structure and allowing cables to be routed through the interior of the robot, sealing from elements, and keeping cables well protected.
</td>

</td>
</tr>
<tr>
<td width="50%">
Added a servo and servo mounting block + gears in order to give the head an articulated axis, making it so I could make the head rotate around. Hollow tube supports mounts the head to run cables, and mounts an LCD screen at the top.
</td>

</td>
</tr>
<tr>
<td width="50%">
Wrote a ROS backend + FastAPI, and React frontend to display either a cute face, or diagnostic information about what's happening on the robot. Gui shows things like wheel speeds, servo positions, battery voltage level, and a few error/faults.

</tr>
<tr>
<td width="50%">
Added corner latches that swing up/down and attach via magnets, allowing me to lock out the corners so they can't move for transportation.
