I’ve thought again about the problem of not being able to do bi-directional motors on the Dalek Project when using just one Piface Digital.
Why should the motors need to run backwards? Daleks never retreat! The only controls I’m going to need are Forward! Advance Left! and Advance Right! (and Exterminate!)
Looking back (which is something that Daleks can’t do anyway), the whole full movement thing came from my idea to build an Arduino Turtle (which was based on an idea developed from a Spectrum project from about 1985). But a Turtle is not a Dalek. Sure, they both have a hard shell and two driving wheels, but that is where the similarity ends.
So now we just need a web interface to control the Dalek’s movements forward, and to the sides a bit. All the while we need to be able to see what the Dalek sees from the on-board camera…
