Late night droid work

Did a little more work to the logics. They are starting to look more like the ones on the games.
Did some soldering and chip replacement on a new PICAXE.
Last I put some wheels on R4 so I can move him around. My next order of motors come in at the end of this week so he will be moving soon. I also got a spare pair of motors for back up or for my future K-9 from Doctor Who.
