Parallel gripper or rotating gripper? Why not both? Stringman uses a linkage that produces a near parallel finger movement for fine grasping but still opens wide to get around large objects.

I like how the control arm transits the pantograph stabilizer linkage’s pivot point

we need a video of it handling a strawberry as thatd be the true test to see whether or not it’s capable of handling very fragile items

Thats a great idea. I know i could teleop pick up a strawberry with it, but its more interesting if I can get DiT or Pi0.5 to do it.

@batsuev_es for a variant this is genius

"4 bar linkage" will give you parallel (if im remembering that correctly. I like the style of this one

Clean hybrid kinematics. Does symmetry hold across the full stroke?

Im assuming at full open some magnetic field or suction holds the object? Unless accompanied by another opposite arm.

That‘s super cool!

that’s really nice, the linkage motion is super clean

Yo, open DMs

I don't see anything from you, but then again, I dont think X dms always work. Try discord.
