I sure do hope somebody has some good ideas on this one...
We are working on a prototype one-off setup for a customer that will transport a 2,000 lb. load across a concrete floor and then return to its original position. The transport is in a straight line from point A to point B.
During workup we built the carriage, which is hydraulically wheel driven and includes a steering axle mechanism, and it works well. Our guidance was planned through a recessed floor railing but the customer now says that is unacceptable (dirty work area).
I'm considering a couple of options including laser guidance to target and floor embedded radio. I'm wondering if anyone has other ideas or knows vendors that might have employed similar solutions.
The envisioned system would work by pressing a "Send" button or command and travel about 25 feet in a straight line at low speed. Once unloaded, a operator would press a "Return" button to send the carriage back to its original position. Guidance must not employ devices overhead, raised from the floor, or recessed in a manner that will collect dirt and grime. Accuracy of +- 6 inches to either side of the travel line is desired.
Any ideas or help would be appreciated!
Thanks,
Jake
