Alright, so pressing a trigger with the pencil would not count as "touching the Robot."

Thanks!

I can see how using a power switch or reset button would mess things up: our robot has those controls on its side, and its incredibly hard to activate them without messing up the positioning of the ...

How important is the voltage displayed? I would like to display the raw sensor readings, to make it easier to collect data, but those do not have units. The display would then read: "Voltage: XXXXXX". Must we include units?

Yes, I understand that part. I'm referring purely to the procedure to start the robot/run. If we use the pencil to push or poke the robot to start the run, would that violate the rule?

I can see a way this could be interpreted if the rules mean that the robot needs to have a sensor to detect a ...

Rule 6k notes that we "may not touch the Robot to start it, ... or 'push' the Robot to get it started." Does that mean even if we only use the unsharpened #2 pencil to interact with the Robot, we cannot touch the Robot or move it with it?

The description of the event determines participants must develop an ORP/Redox Probe, but otherwise in the rules it says nothing about what is considered one. It focuses on measuring NaCl concentration; is it possible to use a conductivity sensor instead of an ORP sensor?

My detector has issues with multiple measurements in succession, i.e. some of the strain is retained between measurements.

The Arduino Uno I'm using has this reset button on the board, allowing me to rerun the program and tare the device again.

I don't think there is anything in the rules against ...

Oh wait, another question might have answered that: https://www.soinc.org/one-faq-says-stand-alone-non-dip-chips-are-allowed-while-another-says-soic-chips-arent-allowed

Is the bare HX711 considered a surface mount chip? And by "not connect to anything else", does that really mean I can't connect ...

I came across this question regarding SOICs , which might render the HX711 useless. Since the HX711 is a SOP16 (I'm using a SOP to DIP adapter socket to put it into my circuit), will it be illegal because it says SOICs are not allowed?

It's a little confusing because it says SOICs implement ...

Why doesn't my sensor produce a voltage? I will use strain gauges in a Wheatstone bridge formation, which will produce a voltage, then measured by the HX711. I suppose the voltage produced isn't being measured directly by the Arduino, but is that a problem?

Yes, I do have a bare HX711 chip implemented in a circuit on a breadboard.

But when I'm making the graph of voltage vs. applied weight, I'm using the HX711 library (to get voltage). My question is, is that illegal?

I'm assuming making the graph is part of the calibration process, and I'm using a ...
