Answered: modifying sensor casing

We are not allowed to modify sensors as per R15. My team has no intent to do so but only modifying the casing. this picture is what we have done to a quad encoder to make it fit into the robot.

The sensor itself remains in it’s original casing, and the function is still exactly the same, the casing is only cut a bit in the sides to fit between the screws. And if this is not permitted can we still use the encoder as long we place it somewhere where it would fit even without the modification?

Let’s take a look at the exact rule.

As such, modifying the housing of a sensor is not permitted. Using a modified sensor of this type is prohibited.

Okay, so if I were to make housing for the gyro out of vex steel would this be illegal? Similar to cutting into the housing of the encoder it’s not modifying the sensor in any way (the casing doesn’t sense anything) but only what is protecting the sensor which you have said is illegal even though it’s not mentioned in the rules. Also if the sensor get scratched would it make it illegal to use? The cut we made into the encoder is pretty much a deep scratch.

Yes, if you only use VEX legal parts, of course you would be allowed to make a housing for a sensor.

Modifying electronics in anyway is clearly mentioned in the rules, please see the above post.

A simple scratch would not be considered a violation of <R15a>. The picture you showed us depicted an intentionally modified sensor. This sensor is illegal for competition use.

Though I don’t see how modifying the plastic changes the electronics which are inside the plastic I’m not going to argue anymore, because I don’t want you to be mad at me next time I ask a question :p.

We ask you to please thoroughly read the VEX Skyrise Game Manual before asking any questions on the forum. Here’s <R15a> for a second time for your convenience. I’ve bolded the pertinent section.

Modifying the plastic sensor housing is an example of altering a sensor from its original state. This is not permitted.

Well thanks for the answer we can still use the modified encoder for other STEM related things, So we have that going for us, which is nice.

You’re welcome.
