We’ve used the Rotary Limit Switches several times.
We used it last year as the “bottom out” signal for our lift mechanism.
We used it Breakaway, again, as a kicker ready signal for our spring loaded kicker.
It’s highly adjustable position wise. Which means you can mount it in a variety of places and positions. It’s far more robust than the micro limit switches. I’d use it again. It’s a good switch if you need something robust.
I think some people have forgotten what the purpose of FIRST Choice is, not just here but on other threads. Before we start game speculation, we should remember that it’s supposed to replace the costs and logistics of sending a lot of parts to teams by making most of those parts available but only if the team wants them. This allows them to put less stuff in the main KOP and make a greater variety of stuff freely available to teams.
That means that game-specific parts aren’t really likely to appear on FIRST Choice, because everyone will need them; they’ll instead be in the regular KOP. FIRST Choice is more like our run-of-the-mill KOP stuff that FIRST felt wasn’t worth sending to everyone. They either wanted to add it to the KOP and decided it was too specialized, or they had been putting it in the KOP and seeing a general disuse of the item.
Since the 2010 wheel mounts was a rather specialized part specific to that year, and due to the fact that they had a tendency to cause the frame to deform when it moved, throwing off the alignment of chains in some cases, I wouldn’t be surprised if AndyMark donated them just to get an overstocked item off of their hands. This doesn’t mean they are inherently bad, but it wasn’t worth buying them at full price (in my opinion). They would make interesting arm mounts, especially if they were used in conjunction with the nifty slew bearings donated by Igus .
i found the pneumatic muscles interesting, but that’s just me. i don’t remember if they were legal or not before now, but the availability of them is what caught my eye. everything else seems normal, including the linear stuff, we actually used the bearings by bwc (the double v bearings) for a crab/swerve drive.
