![]() Between this and the field delays, I actually had a student ask me something along the lines of “how can such smart people screw up so badly?” This isn’t something that we should just shrug off. To has real time scores as far off as these are completely erodes the public and team’s trust in FIRST and the GDC. This is far from the first time that FIRST has screwed up real time scoring. I can’t do better anyone who can should do so before the end of the season and give one to FIRST for their use. I am sure everyone had hoped it would work, but that’s just not how it works in the real world. Anyone “in the know” or take a look at the field to confirm? I can’t find somewhere where FIRST lists the sensor that they used, but this family of sensors pops up quite a big when I google around for low cost load cells. I don’t think I have any of the documentation on my computer anymore, but I’ll email around and see if someone else has the part number.ĮDIT: FC-22, the 0-10 lb version. Using an electronic postal scale to measure the force at the same location on the lever, these issues went away. However, we had similar issues even using bricks. We were using it as a thrust test stand, which is not a great environment for a load cell because there is a bunch of vibration. Clearly we were sampling way faster than the sensor was updating. I’ve attached one of the resulting data files – as I recall our issue was not with a given run giving weird data, it is that you just couldn’t get the same thing twice back to back. ![]() Basically we took raw voltmeter readings – clearly you could do a lot post processing to smooth it out. I believe was a custom Arduino rig, but I am fuzzy on the details. Probably because it is a little vague, and perhaps a little premature. Can you give more details? What internet sensor were you using, what circuit was the sensor in, what was the resolution and rate of the measurement?
