[comp.robotics] Insuring data integrity in dirt

n8243274@unicorn.WWU.EDU (steven l. odegard) (09/08/90)

I prefer working with MS-DOS formatted 3 1/2 inch disketts, but the
shop environment is entirely too dusty for the media to perform
satisfactorily.  I propose sealing a disk drive with a disk in airtight
steel casing.  May I ask experienced technologists what method is most
employed for carrying programs to CNC machines.  Yes, I am familiar
with paper tape, but who uses paper anymore?

      Some of the Japanese machine tool manufacturers are using "smart
cards" for that purpose, and readers are provided on some newer machine
tools. 

      Or you can have a comm link to the machine tool controller, and keep
the removable media off the shop floor entirely.  This can even be retrofitted
to some controllers with paper tape readers.

The system I'm using uses a 40 foot cable between the robot and it's
controller.  The controller can interface with a PC (RS-232) allowing
up to 50 more feet.  Thus the disk drive doesn't have to be in the shop
environment.
