What is a doinker?

[Ethan26]

Sorry for my dumb question, but I don’t know what it is, or its use in competition. I am assuming it is a mech for clearing out the rings in the corner, but I just want some reassurance. Thanks in advance.

Yes, and used as an extra arm for game object manipulation (tipping goals, goal rush, etc.)

Rings out of corner in high stakes

What are the different types of robots/features?

(Pertaining to wall stake scoring) Lady brown mechanism (or called “lb”): Hard to explain. Here are some videos though: https://www.youtube.com/shorts/5syIdZqAFb0 (not the best, but has a good view) (from 1412E robotics) https://www.youtube.com/watch?v=Aa6HvUxea9Q (go to around 28 seconds, great lady brown mech, hard to see though) (credits 18522R) https://www.youtube.com/watch?v=hZeap_ljkuE (credits to Riley Markley) Fish Mech: Similar to lady brown, but much simpler, but reliant on moment…

Yes, a doinker is usually a pneumatic powered mech that clears Rings out of the corners so you can place Mobile Goals there.

Thanks for clarifying that. I’m always amazed and excited to learn all these vocabulary words every year

You’re not alone…

I had to deny a few posts to this thread referencing names for mechanisms that are not in any way appropriate for the forum. It may be wise to consider how y’all refer to mechanisms, especially if you’re preparing to discuss them in judge interviews and your engineering notebooks!
