From what I've seen in those pictures, (
1 &
2) It doesnt't look like it has any balencing mechanism in it. I cannot imagine what it must be like to go up stairs. Actually, it must feel alot like the Millenium force lift mechanism...
I think this wheelchair ..err.. tankchair.. is better suited for heavy-duty outdoors trips and camping than an IBOT, and vice versa the IBOT is much better suited for home and city use.
Very intimidating, I must say. They just need a (poofball) cannon to complete it for 100% tank credit.
