And now for something weird...

Ok...hmmm...maybe...meh...still just a clickbait. I was more impressed by cubli, or triple inverted pendulum. And more entertained by tripteron.

also don't see this as particularly innovative.as similar mechanisms exist, like elephant trunk from Festo..

I was hoping for some good numbers but after going through lengthy article they do not have them yet... they only planned getting to that eventually. I guess my critique us harsh because they made me go through so much text to find out that they don't have it yet. Hence the clickbait remark.

So far manipulator weighs about 3kg, it is 1.2m long, estimated payload is in the neighbourhood of 6N or .5kg., there is no mention on repeatability, agility, etc.

still working on kinematics transforms, which is why this is only trashing around instead of making coordinated motions. And since the actuators are pneumatic, rigidity and positional accuracy are not going to be there. But this is nor exactly a problem as pneumatics could be seen as simpler,safer and easier to work with at least at this stage. And it would still be in the class of collaborative robots (safe for human interaction).but then... Not many would need another sloppy robot. Plus, this one is just too noisy

I thinking making small 6 axis robots (Stewart platform) and stacking them up would probably be more interesting while providing similar range of motions.

I thought it was cool because it looked organic. Nothing more.

that it is...

one can easily make things like organic by simply making the system sufficiently complex - by connecting more joints.. this has been already done with articulated arms, snake robots etc.

they just rushed to publish papers as soon as thing was put together mechanically. and it is cool, just does not work yet. they need to work out math. then payload, repeatability etc need to be determined. this is a robotic manipulator arm so i would really like to see video where it is manipulating things... pick and place or whatever. standard performance test is to cycle between two points 300mm apart after lifting up 25mm above each of the two end points. that will be much more fun to watch. this video is equivalent of boston dynamics robot dog laying on side and kicking leg, yes it moves but that is nothing compared to seeing to actually walking, going over obstacles, and slipping on ice.

Why not just add some AI, give it goals and feedback, and let it train itself?

‘Horrifying’ mistake to take organs from a living person was averted, witnesses say
Natasha Miller says she was getting ready to do her job preserving donated organs for transplantation when the nurses wheeled the donor into the operating room.

She quickly realized something wasn’t right. Though the donor had been declared dead, he seemed to her very much alive.

“He was moving around — kind of thrashing. Like, moving, thrashing around on the bed,” Miller told NPR in an interview. “And then when we went over there, you could see he had tears coming down. He was crying visibly.”

The donor’s condition alarmed everyone in the operating room at Baptist Health hospital in Richmond, Ky., including the two doctors, who refused to participate in the organ retrieval, she says.
