I, for one, welcome our 6 ton steel spider conquerors.




The Walking Beast is a mechanical creature that walks on 8 legs! Weighing approximately 12,000 lbs, it stands 11 feet tall, 8' 4" wide and 23 feet long! It is capable of transporting 8 people including the driver. It has a step height of 41" and a stride of 5 feet!

The machine is powered by a 454 cubic inch chevy V-8 married to a modified TH400 trans coupled to two klune extreme under drive planetary gear boxes, uses a rockwell 2 1/2 ton military axle to supply power to the leg crank shafts, The final drive ratio is 125:1. The legs are supported on a 4 link system and uses 56 pivot points and 114 bearings.

This is pretty darn cool. Are those Hoekens linkage for the legs? Good design. That way the feet move backwards in a straight line to propel, and then lift up off the ground and move forward in an arc to reset for the next step. Nice shocks on the feet too. Still not as quite graceful as I would expect, could maybe use some kinda series elasticity in the drivetrain?
