This is the start of the second type of industrial robot in Punch Bag. This one is a welder; able to get into smaller spaces than the big heavy robot.
It s adapted from a pencil design for a War Droid that I drew while on the train returning from last years Bristol Animation Festival (I was reading ABC Warriors from 2000ad at the time).
Obviously the weapons are being replaced with tools' etc. The polygon model is sticking pretty close to the original. I really like wanted to make that odd spine joint with the two pistons and hinged joints. Should be interesting rigging!
