Sitting at a campsite in the middle of nowhere when Benny Bassani’s “Satisfaction” starts playing far off in distance, and I’m suddenly transported back to Capture the Flag at the AP in 2002-2003. Some memories are deeply ingrained.
Reminder that every 10 minute job is one broken bolt away from being an all day ordeal. :-/

This is a picture some of y’all can smell.
i picked up a GLEDOPTO WLED controller because it fit my hardware needs and figured out how to re-flash it with a different firmware. Maybe this will be useful to others who have a similar need.

nice hat! ;)
I’m slowly working on the inverse kinematics for the legs so the feet move forward and backward instead of in arcing motions to keep forward motion as straight as possible.
Next up is specifying azimuth to move and letting the code handle the rest. It’s “simple” math, but fun and challenging.
Quads are neat because you have to consider center of gravity when lifting a leg to keep it from falling over, so subtle shifts to the adjacent legs are required. You also have rotation to use that keeps all four feet in the same position and twists the body.

I should probably add some content here. :)
Recently I’ve been working on building an RC quadruped robot. This is v2, with a lot of learnings from v1. Physically it’s a SMARS Quad running an ESP32, PCA9685, and FS-IA6B receiver running Micropython.
