Depends what level of robotics you're working at.
Industrial robot arm motor control loop? 1000Hz, single-threaded, dedicated CPU core or even an FPGA.
Robot vision system? 30Hz, tolerance for occasional dropped frames, and some lower priority tasks like saving audit images which are nice to have but not critical. A small monolith with several threads would be a fine choice.
Assigning robot-sorted widgets to customer orders? 1-5Hz, go ahead and use the web coding practices where 200ms is considered a fast response time.
All of these are serious robotics - but they could reasonably be coded in very different ways.
