I was reading my Episode 3 visual dictionary when i found that crab droids can be surveillance drones at 1 meter - or trailblazers at 6 meters! So i made a 6 meter crab droid at minifig scale. It turned out pretty well if i may say so myself and the only problem it the fact that its front legs are a bit to heavy. If you have any comments on improvements then feel free to comment and rate.
About this creation
Front leg design. All the legs are different, strangely enough.
Middle leg design.
Rear leg design.
The ugly droid up close.
The body. Whats weird is that its legs dwarf the body.
