What is Rosmo?
It's a modular set of open-hardware components that can be assembled into robots of different complexity and price.
It's all based on ESP32 so should support MicroROS work.
There are a number of different needs for 'starter' robot kits.
Software that's interesting to us right now includes:
Linorobot2 C++/ Platformio / Ros2

Hadabot (Micropython ROS2, Docker)
