(www.independent.co.uk)
This is a most excellent place for technology news and articles.
There are plenty of instances in anime where mechs (I guess not specifically Gundam) have wheels or skates/wheels, like Code Geass. I think its mostly so they don't have to animate walking on the ground or draw different leg movements/positions.
Edit: added stuff about drawing.
gundum suits arent real dude its fiction
thats just a lot of car parts assembled incorrectly
