Pollen Robotics and HuggingFace are doing a lot for robotics right now!
Wonder if it will get adopted (huggingface robot) I noticed the eyes/cameras go behind the neck thing for sleep mode

Re: Hand: open-source Robot Hand
#32Here is what I’m more keen on, rather than the human-like robots that we are all expecting. For instance, I would like a wall-mounted or floor-standing multi-arm robot that serves as a kitchen assistant. One can add or reduce arms as needed/desired. It is custom-equipped with a fire extinguisher, thermometer, and the usual must-haves for a kitchen. It will hold the cutlery, plates, and other items as needed. It will also advise on the likes of, “No, salts usually go in a pinch, would you like me to add in just about 5 grams?”
Thus, similarly for the garage, the DIY table, etc. Just Arms would be good.

#33The world is designed with humans in mind, it's great to see robotics evolve in this direction to take advantage of that!

Tbh I would rather not have computer-guided knife-flinging arms in my home, be them on wheels or fixed to the wall.

#35What jumps out at me is the $135 bill of materials.
What a time to be alive!
Re: Hand: open-source Robot Hand
#36This is great, but to make a comparable hand, we also need very sensitive sensors, at minimum pressure and temperature, across the entire surface area.
Re: Hand: open-source Robot Hand
#37This looks like a nice, approachable robotic model of a human hand that can be printed and experimented with. But... is a human hand the best design for a robot to grip things with? Or could we surmise that the human hand evolved as a pretty good hand given the materials and senses that were available to evolve humans from , while in theory a totally different design might be optimal for gripping when constructed fro…
A human hand is probably the most appropriate design for a robot to grip a variety of things that were designed to be gripped by human hands. For any one specific thing, be it a doorknob, a rope, a sheet of paper or fabric, or a pair of scissors, there's probably a different design that's several orders of magnitude simpler and cheaper, and also much stronger and more reliable. Single-axis parallel grippers, circumfe…
As an aside, this "robot tentacle" paper was referenced in a recent HN story: "SpiRobs: Logarithmic Spiral-shaped Robots for Versatile Grasping Across Scales"[1]
Seems like a pretty high bang-for-the-buck for versatility and capability with only a few cables controlling it.

I agree that there are some robotic designs that unnecessarily mimic human limbs. I have in mind heads, and feet (instead of wheels). A hand however, is useful because so many manufactured objects have been constructed for their purpose.
Feet are used for roughly the same reason a human-like hand is preferable - human-designed spaces tend to not be perfectly compatible with wheeled locomotion.
The ability to negotiate stairs is table stakes for a household robot. It's already a pain when one's Roomba-like is defeated by a small ledge...

Absolutely, though I'd be ok with just pressure as a starter.

I have a parrot (whose beak is sharp enough, thank you very much) that loves to grab a knife out of the knife block and spin around with it.
I have to put a towel over it though today he pulled the towel off and still grabbed the knife and was holding it up when I turned around.
