All I can say is WOW
You have posted many of your lego inventions, and everytime I wonder how you came up with it.
I have been mentoring FLL teams for 4+ years and, I admit it, stuck on a basic design (mainly becuase its easy for the kids to understand and build).
Do you mentor an FLL team Tytus?
Are these crab designs as agile as their FRC counterparts?
Could you post one of the control programs for these?
Thanks.
