We am working on a project to build a prototype 3D Tracking System  
which is to be mounted on a boom to the ceiling using aluminium shafts.
We hope to utilise  optical shaft encoders to measure the angle of
rotation of each joint and one to measure the translation of the
object at the end of the shafts. 
From these angle measurements we are to calculate the exact position
of the object in 3D space.
The encoders need not be very accurate, but reliable for the project at
hand ie. noise free.

We are looking for information/help which anyone canm provide on the 
above matter especially from those who have worked on similar projects.
We also need information on the encoders in particular
ie. which company to contact, price ranges, what encoders would be 
suitable for a prototype etc. etc.

Any information provided would be much appreciated. Send all queries,
info etc. to:-

    kyam@godzilla.cgl.citri.edu.au

Thanx in advance.
