Herbie's Brain and Inner Workings….

In the beginning, Herbie's central nervous system consisted of several electro-mechanical controllers that formed his brain, a pneumatic system with air cylinders under the hood and in the doors, a remote control unit for external activation, a strobe system, halogen driving lights, and because he still had his original 6 volt electrical system, we added a 12 and 24 volt electrical system to help with some of the other everyday functions. Since then, we have replaced the controllers with a new laptop computer (his new brain) that controls up to 128 servo's simultaneously and have added some extra features such as electronically controlled air shocks on all four wheels, servo driven headlights that can look left and right as well as up and down and visors that blink, oil (water) ejectors on his rear wheel and in the engine compartment, and more.   Overall, he is pretty high tech...

A quick look under the hood shows the amount of wiring and controllers required for Herbie

Just another view of

It was important to keep the

power distribution clean

Extra power sources and

air supply are hidden

behind the rear seat

A 3000 PSI scuba tank and high

energy batteries helps Herbie

meet all his needs 

It takes 3 pneumatic solenoids

 and 2 cylinders to open and

close each door

The connection to the existing door post really turns out to be quite simple

Inside the car, there is one

control panel that handles

all functions

The main controller (brain) consisted of a 1/2 rpm motor turning a cam and

12 switches
