Position and orientation control on top of my speed controller. I used the technique in this paper: Y. Kanayama, Y. Kimura, F. Miyazaki, and T. Noguchi, ‘‘A stable tracking control method for an autonomous mobile robot,’’ Proc. IEEE Int. Conf. Rob. Autom., 1990, pp. 384-389.

- Should I fix this bug? - It’s no longer a bug… it’s a feature.

These are two independent speed controllers (one for each wheel) keeping both average speed of 0.4 m/s across 2.5 meters. The robot oscillates a bit, but the trajectory is fairly straight. I think I’ll try to use it as a building block in the trajectory controller.

Imagine 1994 pixelated games with cinematic effects. I coded a real-time shallow depth of field effect on a 30-year-old computer. Full details and code in this thread: x.com/uavster/status/1750657907589255480

The 486 DX4 turns 30 years old in March. It's the CPU that got me into real-time graphics and the #demoscene. That’s why I target it in almost all my #retroprogramming projects. To celebrate, I've coded a blur effect in true color optimized for the DX4! Details and code in this X thread: x.com/uavster/status/1741668849336946807

Voice commands are finally here! I spent weeks optimizing the onboard ML models to get to this latency. Subscribe to see how I develop HF1 in the open, and follow me on X for more technical details: x.com/uavster

I had my doubts about carpet floors, but they turned out to be fine.

HF1 can now transcribe speech in real time. All the processing happens on the onboard Jetson Nano. By processing on device à la Apple Intelligence, instead of solely relying on a cloud API, the robot can react while the user talks. On the other hand, avoiding third-party APIs is of special importance in home robots for privacy reasons. HF1’s Jetson Nano is the cheap old one, not any new powerfu...

This is just a concept of gestures and expression. All robot reactions are scripted, but I'm working to make them a reality. Subscribe to see how I build HF1 in the open!

I can now calibrate my robot's cameras wirelessly. No need to connect a monitor to the Jetson. Added camera streaming to NVIDIA's capture program with GStreamer's python API. Just because I couldn't take my monitors moving out of the US. Who would think constraints can be good?

I still have to make some chroma adjustments, but here's HF1 streaming what it sees in stereo to my laptop! Under the hood, a simple encoder-decoder GStreamer pipeline with frame composition of the two stereo frames.

I keep finding my old songs in this time capsule of a hard disk. This time, it's a 2006 file called Buy Your Freedom signed by my back-then musical alter ego: SoNAR. It was probably a study on drums, composed with ModPlug tracker (every beat) with the Slayer VST. Here's a quickly edited music video with clips from @FreeHDvideosnocopyright. Use the music as you please, but please credit me.
