Give it ago, for as little as £20[0] you can get a Raspberry pit kit which would let you build something similar to a micro mouse, ( I'm not sure if the actually raspberry pi is included/required.)

That's interesting, I actually have two Pi Zero's laying around I bought ages ago for another project. Though getting this kit shipped to Russia might range from a non-issue to challenging and expensive.

edit: yeah it's not on the list of countries they ship to which means if I were really insistent on buying it I'd have to use a mail forwarder which would cost like 2x the kit itself
