Re: What COTS parts would you like to see?
Smaller 3/8" hex bearings. Ideally ones that could be used in a 1x1 tube. So like 7/8" OD with a flange. We used crummy conveyor bearings from Grainger with our collector, which surprisingly didn't fail during competition.

Re: What COTS parts would you like to see?
A lot of the industrial sensors do not pull low enough to reliably switch the Roborio 3.3 Volt digital input. A packaged opto-isolator that sinks the input to the roborio level would be nice. Maybe even with a transistor that inverts the logic back.

Re: What COTS parts would you like to see?
I'm sure I'm missing something and some of this has been alluded to, but how about a small, lightweight, easily mounted replacement for a window motor? Something with low rpm and modest torque. The window motors are flimsy and hard to mount. I love the versaplanetaries but would prefer not to have to use a 3 stage reduction to get to the sub-100 rpm realm.
Clue me in on what you use in these applications. |

While a good high torque servo for FRC applications would be very welcome, especially one with its own encoder, what I would rather have is a new transmission designed specifically for window motors (all of them), windshield wiper motors, door motors, rear window motors, etc. A transmission of this type should be capable of interfacing with gear, square, or module 2. It should be capable of direct drive config, round or Hex Output Shaft and have the ability to mount an encoder (potentiometer) to it. There is an advantage to these kinds of motors if they are legal. There are lots of different types, some are very inexpensive, some are self braking, and you can get them at just about any corner auto parts store. The problem is there is no standard means of connection them. If it was as simplement as 3 screws to mount or replace more people would use them. And some of the currently legal ones are crazy powerful. But it can take an entire build season to figure out a way to mount and connect one. I'm not sure why they are considered flimsy though. Maybe they weren't mounted correctly? |

Re: What COTS parts would you like to see?
This product used to exist from AM, but it required such a thin inner race at the points that the bearings would fail catastrophically at relatively low loads.

Re: What COTS parts would you like to see?
FWIW, I would love to see FR6's with a 3/8 Hex bore make a come back, I've used them in 2013, 2014 and 2016 without issue. (Bought stock when they were discontinued) From what I've seen, they can be used in Auxilary mechanism, specifically high reduction gear boxes and intake type gearboxes without issue.
