The dome was simple, after adding a wooden disk to the bottom for Lazy Susan hardware and a blue LED/power supply for the "eye", all that was needed was paint.
In keeping with Steam Punk, a barrel was needed for the body. A nail cask would have been great but I have not seen one of those in years and any "antique" ones cost! So I built one. Using two wooden disks for top and bottom, wooden slats were Gorilla Glued into place and after drying, the unit was sanded to a barrel shape.
PVC was used for the legs and to make it roll, casters were mounted to the bottom of each leg.
A little stain and paint along with a few "found" Steam Punk objects (gears from a bicycle, leather from a belt, flex conduit) and There You Go! Steam Punk R2D2!
