It has an 8-bit microcontroller, it's much different at programming and
more embedded than the ARM systems running GNU/Linux.

I have no experience and no interest in robotics.  I used the Cubieboard
as a server for a single-user Web app (which wouldn't work with just
512 MiB of RAM) and the BBB as an external SPI programmer to flash
coreboot in my laptop (and also as a EHCI debug device to find that the
laptop fails to find its RAM).

It's better for some projects, not for others.  You can use it with
fully free software, while some boards have e.g. wifi with nonfree
software.  (The FSF-endorsed 3d printers use Arduino-like boards.)

Arduino is popular, the amount of available documentation and resources
should help.
