11-17-2007, 01:58 PM
The Sandman is an 800lb walking robot with 16 separate remote controlled movements. He has a Gasoline and propane flamethrower in front and a gasoline machine gun mounted in the rear. When his mouth is extended his total length is around 11'

He has Harley Davidson exhaust pipes mounted on his sides capable of shooting 15 ' flames. The front flame thrower capable of shooting flames 20'. He is operated using two Futaba Helicopter radios.



He is used for various entertainment events.


Unfortunately, this does not show him walking,.

Sandman uses a small victor speed controller for driving the two wheelchair motors for forward and backward movement. All the control system were handmade using old magnetic tape drive computer parts, servos, relays,micro switches and motors. The mouth is extended and retracted using a boat hand winch. I modified the winch by adding an electric motor and several tilt switches. He carries a SCUBA and propane tank inside for running his pneumatics and flamethrowers. Two diesel electric batteries are mounted under his pivoting front end for 24 volt electrical power. Gasoline can be injected into the flamethrowers with a flip of a switch.

All I can say is this: we don't get nearly enough 800 lb fire-spewing robots in these forums. Bravo!
