How the flip do I build a flipper?

[Cosmosrobotics (Noah D)]

I’m on the home stretch of my antweight flipper Nova and all my electronics work and it drives. My servos turned up a couple days ago and ive been trying to design my flipper.

(sorry for no screenshot I’m writing on my phone)
I have got my chassis with drive mounts and a servo mount CADed in. What I’m really stuck on is how to get the rotation from my servo to my flipper and how to hinge it.

those are some pics of the bot with the flipper shown.

cheapo servo I bought on Amazon that is surprisingly fast and strong.
Ive Seen some people do something with like a little linkage to the flipper but I have no idea with the hinges. If anyone has any pictures of how they did it it would be great to point me in the right direction. And if all goes well see you at the June ant event.

Actually had a similar thread to this come up in our Facebook group recently so I’ll just repost some of the bits from there

In terms of linkages, you might find this super old but super useful diagram useful

And as example bots, check these out. One is from Shakey’s site Nuts and Bots, where Shakey has screwed into the printed walls of the robot for the hinge, and used nuts and bolts between the linkage.

The other is built by Michael of Clements Combat Robotics. You can see here he’s used 1.5mm modelling brass for both the linkage and hinge.
