You can build a Technic mechanical and optical system to control Mindstorms
Scouts and Micro Scouts. The lights and optic cables from the FOS (Fiber
Optic System) rotary LED assembly can provide the light sources and channels
to the light sensors on the Scout and Micro Scout. No PC, no programming,
no IR tower, and no RCX communication needed.
The FOS (Fiber Optic System) generates light with 8 LED's. Axle rotation
selects one of the LED's at a time. One FOS could control several Scouts
and Micro Scouts sequentially. Electrical power causes the selected LED to
glow. Pulsed power can signal the Scout or Micro Scout with light codes
corresponding to their built-in programs. Several types of Technic-built
mechanical switches could allow manual control of the signals. The rotary
FOS switches power off between each of the 8 LED's. Gearing or leveraging
the axle to the FOS can allow enough manual control to select an LED and
then pulse power to create the light signals. The flexible fiber optic
cables carry the light to the light sensors on the Scout or Micro Scout.
A Scout runs 2 external motors. A Micro Scout runs 1 built-in motor.
