Slip ring? At least that what it looks like for a continuous turret.
Engagement ring? OMG! Congratulations for you!
We finally found the right slip ring supplier, the ceremony is in August!
From a reverse image search, it looks like it’s a slip ring designed for a CT scanner. This could definitely be it.
Am I the only person who saw “6502” and thought it was referring to the MOS 6502 microprocessor?
We get that one a lot, to the point of us joking about running our robot on one.
Honestly, that was my guess related to the title before opening the topic and realizing it meant the team.
As others have pointed out, renaming yourselves to take better advantage of the glorious team number you were assigned?
6061 and the other Aluminum allow #s also kinda dropped the ball on that as well.
I wish, but our team branding is intense as is. Plus, do you know how hard it was to get a bunch of high school boys to wear coral?
I was thinking something along the lines of flat black shirt with white printing in the same font and layout as DIP chip labels.
MOS technology- Team 6502 with some backronym for MOS
I mean… we’re all using the RoboRIO. I think it’s a fair comparison.
Are these for turrets?
you could see who’s old enough to get KIM-1 jokes
Ok, for those of you who are curious, here’s the part. If you guessed slip ring, you are correct. But, since slip rings with through bores to fit a power cell through are not cheap, I’ve taken to designing my own. The ring is integrated into our current 2020 turret mech, internally. There are 4 brass rings conducting motor current for the 2 neo motors and a pcb ring (the green) for Ethernet (Limelight), A single CAN bus end (terminates at the sparks on the turret) and 3 wires, for the hood actuation servo (y-splitter on the turret). This is an extremely specific wiring configuration, so custom is the only option. All the rings are retained with a 3D printed part, and the brass is soldered to. The black box in the second picture is the contact box, held by two #8 screws and containing a PCB with an RJ-45 jack and some solder pads for the CAN and servo. I might change this to Weidmuller LST-SMT connectors like those found on the VRM and PCM. All of the contact surfaces and parts are lathered in dielectric grease to prevent dust and dirt from power cells from damaging the ring. Overall, this is a fun little project for the summer, and while it might not make it on the robot, I’d love to see it work.
Do you have any idea on potential price?
This is exactly what I thought of doing this season but dismissed as “there’s probably better ways to do this.”
Regardless of the practicality, great job for designing it and good luck to getting it work!
If it turns out to work great, would you mind posting more details? It would be really cool to have a design guide or something for custom slip rings.
right now, it’s looking in the range of 300 dollars. The biggest price problem is the big PCB and the brass plate.
Well, considering it’s alternatives, that’s not too bad. Are you considering selling them? Perhaps partnering with thethriftybot?
