This actually surprises me, considering the number of USB DAQ devices ( like
this, and
this) entering the market. Attaching a simple driver circuit (either voltage or current) to one of the USB DAQ DOs allows for control of most pneumatic systems and some DC motors (single directional / single speed) while the limited AOs can control many of the more sophisticated motor systems.
Not to mention the sheer number of other USB devices that the cRio could control (Enviromental control and monitoring, control feedback through DAQs, Logic instrumentation, ocilliscope signals, etc) and all through a common port (latency, timing, and bandwidth would be an issue on the higher end devices).
This would seem to me to be an easy way to expand the cRio's capabilities while keeping the cost to the end user down.
