IMPORTANT MISCELLANEOUS SYSTEMS
ROBOSAURUS's ears can wiggle and his wrists can rotate outwards 90 degrees.

A Real Pilot inside a Giant Transformer's Head!

FIGURE 14a. Ears Up

Pilot-in-training, Frank Yaeple, Design News, Fluid Power Editor and Co-pilot Bob Correll (visible in back seat) exercise the ears. The extended ears are "wiggled" during performances and have become an important part of the animated "personality" of the beast. Parker 1.5 inch bore hydraulic cylinders (located above the co-pilots head in photo) operate each ear.

 

A Wave and an Ear Wiggle from the Pilot!

An exciting part of the show is when ROBOSAURUS, using just one hand, effortlessly lifts a lightweight compact car up overhead 50 feet in the air. Then using his rotating wrist, he positions the victim to drop it straight down on it's front bumper. A real crowd pleaser!
A pair of Parker 2 1/2" bore cylinders are used to provide the torque for the 90 degree wrist rotation.

What is Inside the Wrist.

FlGURE 14c. Rotating Wrist System

Because of concerns about metal ball or roller bearings brinelling due to shock loads we went to glass filled teflon cylindrical bearings. The bolt together bearing structural support system allows the four claw hydraulic hoses to pass through the hollow center and, thus, stay internally hidden from view and protected from crushed car, sharp debris damage.

 

Perfecting the Wrist Took a Month of Engineering Time!
