 At Liverpool earlier this year, Andy Piper was demonstrating his brachiograph, or lolly-stick drawing robot arm. Ever since I first had my ZX81 I've been mildly curious about robotics but have never taken the plunge. More recently I've been looking at various plotter projects, even bookmarked a few. Seeing this one in real life and seeing how cheap and easy it was to build (and my boyfriend chucking some servos in my direction) finally tipped me over the edge.  This project turned out to be, as billed, the perfect gateway into robotics. It really is very simple to build and there are tutorials online, including from Andy himself . Thanks for all this Andy! Lots of hotglueing ensued. So far this has all been very robust.  To make the wiring neater, I made this little distribution board. First I screwed the Pi Zero down and found that I couldn't plug anything into it, so had to cut a little plinth for it. I'm not going to pretend that installing the software went without
