Craft Me A Bot!

So after an entire summer of me and my macbook, I had no access to 3ds Max. This morning I thought I would mess around firstly to see if i could still model...and secondly as a little test of some robot designs I had in my head:
















They're not very well made, but you can at least see the concept that i was going for. Now these designs are very simplistic, but certainly something I can build upon to craft something that I really love. I plan to model the environment from the character, so further development is necessary.
