Open and Closed Loop Systems (ex. 1.6)

This picture shows an open and closed loop system. It works by using an input as the variable. The input is based on a light reading from the phototransistor, which ranges from 5000(no light) to 0(max light). The variable tells the system when it should continue based on the reading from the phototransistor. It continues to loop until it has the correct reading.


Conclusion:

1. Another example of an open looped system could be a toaster oven, because it will continue to operate until the time variable reaches the specified limit. It would not benefit from feed back because time is a very specific variable.
2. The mouse on a computer is a closed loop system because it will not act until an input gives it specific feedback on how to react.

Variable Fuctions (ex. 1.5)

Here is an example of a variable function that I made using RoboPro. It works by running through the counter then updating the variable on each loop. As soon as the process runs five times the varible will read 5 which will tell the system it is time to stop.

Conclusion:

1. I might modify the plus command to reset a block to 0 by doing a [-5] counter after the system finishes.
2. An industrial need for counting could be used on an assembly line, where the system would count how many parts go through to log the output.
