..snip.. You are most welcome to provide your viewpoint. No need to apologise at all. The problem is two fold locational info and guidance system. The bus problem is location problem reversed but more complicated. For the location problem. Rony's idea of simple short range radio beacon broadcasting it's name on a reserved fm channel is perfect will cost Rs. 1800 or so per beacon - u require a good tx since drift has to be near zero, so hobby fm tx wont do - with solar pack. One could bcast ads, so will actually generate revenue at least in cities. Buses will have similiar device but with collision detction so that bcasts dont overlap. It may still not work too well if the road is a narrow two way street (eg kalbadevi) and multiple buses are within earshot of each other. There is no technically feasabile solution for the guidnaceproblem. Normal guidance requirements are so complex that even a fully functional robot costing a bomb and weighing as much can't work to 10% of any human. A better alternative is to provide properly designed environments eg guide rails with physical markers on stairs. The fm beacon can also work for some cases in identifying exits / entrances loos etc. -- Rgds JTD -- http://mm.glug-bom.org/mailman/listinfo/linuxers
