The telemetry device for controlling the arms
Eight puppeteers operate the Spinosaurus:
- Basic head/body - swivels head, opens and closes jaws, moves neck back and forth, makes body sway from side to side
- Tongue slide levers - moves tongue up and down, side to side and in or out
- Eye joystick control - eyes move, eyelids blink and eye ridge moves
- Front arms - full range of motion; hands open and close
- Cart/body - moves creature back and forth on track
- Breathing potentiometer - inflated bladder inside chest cavity simulates breathing
- Tail - full range of motion
- Body raise slider - raises and lowers body
Rosengrant is the coordinator, and he makes sure that all of the other puppeteers are working in concert to create a realistic and believable motion. The telemetry devices used to control the Spinosaurus range from simple handheld units, reminiscent of a video-game joystick, to bizarre contraptions you wouldn't find anywhere else. For example, the puppeteer who controls the arms has a device that he straps onto his own arms. He then acts out the movement he wants the Spinosaurus to make, and the telemetry device translates his motion into a control signal that is sent to the circuit board controlling the mechanical components that comprise the arm system of the Spinosaurus.
