Here is ours:
(To be completely truthful, it’s only the second most unusual item in the workshop. I’m guessing someone else has one of those, but not the of the most unusual item).
What’s yours?
We have a folded up treadmill in the software/business area that people keep walking into. The reason for this is that we meet in a mentor’s garage, which is also used as a home office.
We at least had several of this variety of calculator:
I believe they got purged.
Not at robotics, but I am part of stage crew/theater tech and we have some very weird things in our shop…
One of the more chill things but very unusual is a Soviet Union flag in the freezer(at stage crew)
There is a dead (I think) cockroach in one of the lights. We’ve named it Steve.
Steve hasn’t moved in over a year.
Sticking with the aeronautics theme, not actually in the workshop, but next door is this:
We happen to meet in an elementary school abandoned in 2012. This means that there are painted handprints on the walls, along with several rooms and an entire upper floor filled with school supplies from the early 2000s. Some things include old computers with crt monitors, and old boombox that has a cd of kids nursery rhymes, and lots of random books.
A tequila bottle pinata I think. Several low end digital cameras, audio and stage equipment I think, and several Thomas the Tank Engine sets for Trackmaster.
So I found out that this is the airplane in the workshop. We also have the wings hanging on the wall in a different room. It’s all going away, soon, which makes me happy (for more space) but also sad (because having an airplane in your workshop is unique and cool).
I’ll get a photo of the most unique thing in the workshop later today.
Of the answers so far, they are all pretty cool, but if the beehive contains actual bees then it is the winner.
My current workshop has so many 3d printed frogs.
In true Dean Kamen fashion, we have a Segway.
I almost forgot to post the most unusual thing. I can’t imagine anyone else has one of these.
What could it be? (No cheating!)
Hey, we have a couple of those in the same building as our workshop. It even has a photo of Dean Kamen next to it and you can ride them through a maze.
New team goal unlocked 
Planetarium projector.
Having our workshop inside of a big science museum gets us all around kinds of cool stuff.
Last year’s Impact video was shot onboard a Pullman parlor car.
When we started the team a little over two years ago, we had to wait for the traveling Sherlock Holmes exhibit to get packed up and moved out so we could move in.
It’s super fun.
Oh wow your team is inside a science museum! That’s so cool!!!
We have an organ! https://photos.app.goo.gl/HxraGNSfFLSgDbV77
