Here is a pic of ours, it's not the best pic, but the frame is made out of big 80/20, and the orange rails holding the robot are adjustable up and down/removable. It's got some big heavy duty casters, so it runs smoothly, and it was a fairly easy build once we had the right 80/20 hardware, it's been great for the last 3 years, and looks pretty slick with the orange and grey powder coat.
