Vince Martyn: 'Orion'
Although Orion was cosmetically finished in June 2008, he is still continuing to get small upgrades and improvements. These include a custom built remote control iris mechanism; improvements to the dome rotation and eye stalk movement and a very slick single box solution for remote Dalek voice.
Orion is also fitted with cold cathode fluorescent tubes, under the fender. They are housed in protective tubes, mid way between the floor and the top of the fender. The positioning means that the only time one might get damaged is when the fender is on it's side, so fairly unlikely.
How it was done...
The slats were made from MDF at 15mm deep and a slot was cut into the edges so that a side piece could be added to extend the slat into the profile of the shoulders. The advantage of doing it this way is that the slats are hollow and this helps a little with reducing the overall weight and also with fitting.
This picture shows the method devised for raising and lowering the eyestalk. Limiting switches were later added so that the motor travel was restricted to stop the chain from getting too tight or too slack. Clearly visible is the large motor for the eyestalk and the two smaller motors for dome rotation.
This photo shows the fender under construction. Note that the front castor needs to go under the "work in progress" front box. This is simply a 'test fit', to make sure that all the parts go together correctly. Once construction was complete, the fender was painted in its familiar dark colour scheme.
Some of the electronics: First board: processes transmitter switches that allow multiple uses for the right hand joystick. Second board: handles signal processing movement of eyestalk or gun. Third board: handles raising/lowering of the eyestalk or gun. Last board: for wheelchair controller and throttle.
