News - FCC bans [my read] "top- and mid-tier" foreign vacuum robot cleaners
as part of advanced foreign-made robots ban.
Vacs with WiFi, 4.4lb including dock and LiDAR, camera sensors.
Bans approval of NEW products, existing exempt
FCC July 27, 2026 https://t.co/EzqNO3lrmk

End-of-week open source vacuum update
- floor cleaning runs in sim (very clunky, often fails)
- Kicad schematic added #raspberrypi CM4/CM5
- changed MCU to STM32G473; will use Arduino to make it more hackable
- depth cameras for obstacle avoidance
- STM32G473 #stm32 MCU, #arduino

Open-source vac update
- Rough BOM nearly complete. Left - parts to purchase. Right - 3D print.
- Vacuum software builds, runs (mock) on #raspberrypi 4 2GB (down from Pi 5 4GB). Set up CI.
- CAD design spec draft. Purchased 3D scanner
- I/O board: battery charging schematic done

[oomwoo @0OMWO0]

End-of-week open-source vacuum progress update
- hired a robotics software engineer (ROS2)
- board schematic now available (very early) in KiCad
- sourced main brush motor assembly, side brushes + motor assembly, cliff sensors + bumper switches
- merged 2 PR contributions

Open-source vacuum cleaner - mid-week update

- decision: use Raspberry Pi CM4/CM5 compute module; cost $95 or $62.50 if we fit into 2GB
- hired PCB engineer for vacuum I/O board; https://t.co/B9VwTvIlFK
- hired mechanical engineer for vacuum 3D CAD; https://t.co/eISM9HUpm2
