My team has been working on our skills auton for awhile and we are at the stage where we are trying to cut down on time. We use the optical sensor as kind of a line sensor and it has worked really well in the past. But now as we are trying to speed up our run, the sensor will sometimes miss the line…

You can try moving the optical sensor downward to account for the overshoot due to the refresh rate, or simply just reduce the roller speed so it’s less likely to overshoot. Another method can be using 2 distance sensors, and use them to control the roller until they get equal readings (ball in the …

I think there was a miss understanding with my explanation the optical sensor is being used to detect the white lines on the field not the balls as they come into the robot. We are not using the distance sensors for it it we are using the optical sensor.

Based on this, most sensors refresh around 20ms [image] Data refresh rates of V5 sensors VEXcode V5 Tech Support I know that the new V5 rotation sensors were a 20ms refresh time when they came out, but I think I remember someone saying that it would be changed to 10ms lat…

Sorry about that, I actually didn’t see anything about using optical sensor to control drive in the post so I just automatically thought its for indexing. You can try adding a second optical sensor toward the front of the robot, and slow the robot down if the front optical sensor stops reading the l…

We were already trying something like that but it sounds like we would have to slow it down anyways. Is there any reason to use the old line sensors instead of the newer optical sensors or is it not worth it?

Based on this, most sensors refresh around 20ms

The distance sensor may be more like 30Hz based on this:
