Robotix interface

[Oloturia]

I was browsing at random some magazines when I spotted this:

(from https://spectrumcomputing.co.uk/magazin ... o_Spectrum )

In May 1985 it was announced an interface for the ZX Spectrum that can control Robotix's motor joints with BASIC.
My brother found a Robotix kit in a second hand market, and now I'm wondering if that interface ever existed or if can be built somehow.

I've done a little search online but there is no mention of such interface.

I found something.

It seems that an interface for the BBC Micro was available in 1986. I don't have time to read the whole article right now, but from the images it seems something that you have to build with solder and a few components. I examined the kit I have and it seems anyway that the motors are driven by switches. I'm quite confident that with an Arduino or a Raspberry Pi and a few relays switches I could drive them.

Now there's a wave of nostalgia, I'd completely forgotten about Robotix, had a set myself way back in the 80's. Never knew you could hook it up to a Speccy, though it was still great fun.
