We decided to make a quick recap and preview video before champs started. It’s been an excellent ride so far, meeting many amazing teams and winning some nice hardware. Here’s to hoping our success continues in St. Louis this week!
It’s so cool that a rookie team has one of the best implemented swerve drives I’ve ever seen in the year of a game where one’s first thought for a drive system wouldn’t be swerve. (unless you are team 16 of course)
Is that a blue light ring? I’d be worried about the blue lights on the tower interfering with your vision code. There was a team at Midwest who tried using red lights, and their code only worked when they were shooting into the blue tower.
The lights are UV helps us get rid of the background lighting.
Also the intake will lower on the auto, the practice bot doesn’t have the necessary feedback that the comp bot has on it. A new intake was designed to bring to OCR. And this one was recently built for the practice bot.
I don’t mean to take anything away from this great robot, but shining a UV light to target the high goal is a huge safety hazard. Even at low intensities, UV light can lead to skin and vision damage, and you’re shining that light in a direction where opposing drive teams will be exposed to it. At the very least, make it very clear to your inspectors that you are using an ultraviolet light so they can make a proper determination of its safety.
At the intensity and wavelength we are running at the lights won’t harm the opposing drivers. UV light gets a bad rep but it is used in a lot of applications, pretty sure there are a lot of people who go to nail salons which use UV light to dry nail polish.
The shot that we like to take (outerworks from the low bar) had issues because at our previous events there was a spotlight usually right near where we wanted to shoot, so our camera tracking wouldn’t work. We could get it to work 100% on the middle goal near the middle of the field, but the bot was not designed to shoot from there. We wanted quick cycles.
We have a mentor who works in the frunit processing industry and knows a lot about UV light and vision systems that they use on fruit sizing and elimination equipment. Spotlights and other light sources don’t emit much uv light at the wavelengths we are using, so the goals stand out like a sore thumb no matter what.
It is actually 18 GA Stainless steel, powder coated matte black. Our practice bot is just a standard finish.
Myself and another mentor have about 9 years in FRC each. But the students are all rookies, we didn’t have help from any of our local teams. We spent the offseason on training the first group of students and they have done a fantastic job.
Anyone who wants a closer look can stop by the pit at Champs and talk to the students they are very proud of their first season
To build on this a bit, the threshold for directly damaging ultraviolet light is well under 400nm. Aquarists commonly use violet LEDs in the 390-430nm range to accelerate coral growth as it hits photosynthetic and fluorescent peaks. LEDs are made to peak in a very small nanometer range, so the amount of harmful UV light is negligble.
You face more danger from household fluorescent bulbs than you do from 400nm violet LEDs.
