I have 3 main computers for my robot:
amdc -- the desktop. Mostly runs rviz2.
sigyn7900a -- the robot's main computer, uses an AMD 7900X processor.
Mini ITX motherboard to save space. 64GB RAM and a rotating rust disk to
backup stuff every hour. Also fronts the OAK-D camera running a point
cloud and object detection. The object detector and point cloud is fed
into code that allows me to measure with some precision where things are
that the gripper wants to grasp.
sigynVision -- a Pi 5 with an AI hat. Runs object detection from a Pi
Camera 3 sitting behind the gripper to help the gripper, well, grip things.
Using rviz2 to watch the two cameras was causing me network hiccups.
Part of what I did was to customize the configuration of the two WiFi
chips for the computers on the robot and also changed how my desktop
used networking. I reduced network bandwidth from 350 Mbps to half that,
reduced latency, reduced retries and made the world safe again. You're
welcome.
The two computers on the robot now also check every 6 seconds to see if
there is a better mesh repeater to connect to so I can continue to have
a pretty good chance of getting nearly 350 Mbps as the robot patrols the
house. I now no longer use a TP-Link AX1500 as a replacement for the
PC's WiFi chip.
If you want to see how I ended up configuring things, then attached PDF
should help explain things.
Your mileage may vary. Void in Utah and in the Northeast Kingdom of
Vermont. Start saving twenty dollar bills for when I start my Patreon page.

Very good. I can't wait to see your demo.
