Generally, Real Robots in anime shows try to be realistic. Anything you could expect from a Sci-Fi movie. No bizarre weapons or hot-bloodedness, for the most part. It sometimes depends on the actual feel of the show, though.

Some good examples of Real Robots are Gundams (minus G Gundam), Macross mechs, and Fafners.

Look at Super Robot.

Running for exercise and picking up trash you find along the way. It's good for the body, mind, soul, and environment! Started in Sweden but is making its way to the U. S.
