It seems to me that the best place to get advice and pointers from fellow roboteers is at live events, many are eager to help and will chat with you about what went into building their robot. It also gives you a good grasp of the scale and shape of the parts on a heavyweight, which is important if you've never seen one in real life before. I thought I had grasped how big they were, and then I went to an event; it's quite different seeing them in front of you. There's Extreme Robots in Manchester at the end of April, and Robots Live in Grantham on the 1st of July. Try going along to one of those.
