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

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.
FIGURE 14b. Ears Full Down
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.
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.
