Hi,
I have a sensor array that moves on a linear track that requires power, gnd, and 3 data lines. So far I've been using ribbon cable to supply this but the cable often gets tangled, inhibits motion by providing elastic resistance, and is generally unreliable physically (prone to tearing).
I was wondering if anyone could come up with a novel way of providing power to this sensor array that is extremely cheap yet is not a hack made from household materials.
I have already considered using a spool for the wire and using inductor coils, both these options are expensive. The only cheap option I see is power rails. Literally, 5 parallel physical rails that the sensor head somehow makes contact with in its motion. I have concerns only with price of components, mechanical stability and complexity, and electrical noise from this design.
If anyone has done this with a robot , could provide me with a link or some pictures of a successfull power rail, or has some new ideas...I'd be much appreciative.
Thanks,
Avital
