Hi guys, I was wondering if there was a way to program the robot to be continuously looking for feedback from a digital input. For example. I have the robot dropping a part through a part sensor but sometimes it drops the part quicker than other times and gets through the sensors before the robot is looking for that input. ---

You’ll want to use the “Thread” command. It’s essentially another program running in parallel. ![image](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/2X/6/60ff30b9a02b7e041bfb9a0e2947558e9e6ece9b.png) Usually a good idea to put a Script command “sync()” at the end of the thread to avoid the robot throwing an error about the thread using too much time. ---

Thank you! I’ll try that out and get back to you!
