This is a construction pod design concept. Capable of doing maintance, repairs, and construction. The two things on top are magnetic "suction cups". They just latch onto large metal materials such as panels or parts. The arms obviously do various peices of work.
thats a pretty neat design and good detail..i like it
Nice detail man. Th scale of the thing is quite big though, looking at the cockpit. It won't be reparing anything in tiny, hard-to-get places.
