ROBOT on ZX!

Hello RamTop Ram> Guys, here’s a question - I didn’t understand what hardware it would be based on Ram> implemented by Speccy itself? Again, dimensions, current consumption... I will say Ram> honestly, the idea is ripening to create a mini autonomous robot based on Ram> Spectrum 48k, something like a vacuum cleaner on the tracks of my old friend. Ram> He is not good at programming and asked for my help. And of course Ram> there are still many unresolved problems. We haven't found the board yet Ram> computer from which we will “dance” further... I would like to know Ram> parameters of your hardware on the basis of which you are going to build Ram> handheld. One such board would be very useful for us: v2_conf2; Plot; core 1, i.e. The Spectrum is slightly larger (for now) than a matchbox. With consumption an ambush, this is a modern z80, but a classic processor in planar. It doesn't have a "video controller", the video controller is in core 2.. via microcontroller, but according to the latest calculations, it can be resolved on a coprocessor. I think a 48k Spectrum on a ULA chip like this will work for the robot. Memory is possible solder 62512. Ports for actuators can be soldered directly toCPU. A good idea, BASIC is very friendly to Spec. Codes are also fast are mastered... in simple cases.
