Very interesting, thanks!

Compared to avr_bridge I really like the time synchronization feature
and omiting the code generation process.

I also see that you implemented a tf broadcaster. Your tutorials suggest
to implement a broadcaster of odometry transforms in the atmega. Did you
try this? I'm a bit sceptical of doing trigonometric operations on an
atmega, especially on floats.

I'm currently using avr_bridge and am quite happy with it. I'm doing all
math stuff (integrating odometry velocity over time; creating point
clouds from ultrasound data) in python, however.
