Questions

1. What does the acronym PID stand for? Is this considered an AI software method?
2. What is the Turing test? Do you feel this is a valid method of assessing AI?
3. Why do you think robots have a problem with negative obstacles such as stairs and potholes?
4. In the OODA loop, what does the Orient step do?
5. From the discussion of Python and its advantages, compute the following. Your program needs 50 changes tested. Assuming each change requires a recompile step and one run to test, a C Make compile takes 450 seconds and a Python run command takes 3 seconds. How much time do you sit idle waiting on the compiler?
6. What does RTOS stand for?
7. Your robot has the following scheduled tasks: telemetry at 10 Hz, GPS at 5 Hz, inertial measurements at 50 Hz, and motor control at 20 Hz. At what frequency would you schedule the base task, and what intervals would you use for the slower tasks (i.e., 10 Hz base, motors every three frames, telemetry every two frames, etc.)?
8. Given that a frame rate scheduler has the fastest task at 20 fps, how would you schedule a task that needs to run at 7 fps? How about one that runs at 3.5 fps?
9. What is a blocking call function? Why is it bad to use blocking calls in a real-time system like a robot?
