I think it's a standard socket for industrial PCs that allows stacking of cards. A card can mount the CPU, another one the wireless, another some USB ports and so on... http://en.wikipedia.org/wiki/PC/104 >> Player >> connects to the hardware via RS232.

It could be useful for such an architecture and is mostly Ada. http://marte.unican.es/ Our robots have a proprietary OS (ARCOS) in the other side of the RS232 for real-time control of the robot. I don't know much about it. > [In industry actuators and sensors are connected via Ethernet (maybe > modified) or a field bus. The latter slowly dies out. RS232 is, well, > quite outdated.] I don't have much experience with robots out of these ones, but USB is still second place to RS232: even if newer SICK models have USB, our models, GPS receivers, the robot microcontroller, the pan-tilt camera units, our lasers, all use RS232... may be they tricked us into buying obsolescent hardware ;)
