Current generation tactile sensors cost a couple thousand $ PER FINGER, and have a real world MTBF of hours. The cost can be solved with economy of scale. The fragility is harder.
- UltraSane 2mo agoI'm picturing humanoid robots having to operate in pairs so they can constantly fix each other.
- lizagub 2mo agoi like this
- lukan 2mo agoAlso so they can watch each other, in case of the humans trying to shut them down.
- aleph_minus_one 2mo ago> Also so they can watch each other, in case of the humans trying to shut them down. That's why the human operator needs a gun. :-)

Are we talking about experimental laboratory ones here? What happens when the Alibaba players start getting into the game? They have plenty of humanoid robots.
- dyauspitr 2mo agoHow much more sensitive do you need to be compared to say a standard mobile capacitive screen and those are essentially dirt cheap at this point.
- LoganDark 2mo agoCapacitive touchscreens are not tactile in any way whatsoever. They are purely electrical, and there are plenty of things (actually, most things, I'd say) which are not sufficiently capacitive to be detected by such approaches. You usually need to measure physical deformation instead, which is much more difficult to do precisely. (There are capacitive approaches to that, but they don't work like a touchscreen)
- lizagub 2mo agoi think you can get some good surface for a few hundred $$ / few fingers here https://xelarobotics.com/ https://xelarobotics.com/
- choonway 2mo agoyep. and with the western funding model, how many hardware iterations can you do before you run out of runway?
- madaxe_again 2mo agoCurious on your take on this, given your domain - is the hardware the principle challenge in your opinion, or the software? >> It will be difficult to match this scale of breadth and depth of data for physical tasks. There’s no straightforward equivalent of “just Efficient learning, generalization, and adaptability / on-the-job learning seem like requirements. Isn’t this the idea of NVIDIA’s Isaac? Model based adaptive learning in virtual environments for robotic systems? Or is this oversold?
- GlenTheMachine 2mo agoOmniverse (new Isaacson) is good, but no existing dynamics engine does an actually good job at contact dynamics.
- amelius 2mo agoI don't think that's true. AI could work around all the physical imperfections. Just imagine yourself controlling an imperfect robot with some joysticks or maybe a sensor suit. You'd certainly do much better than current robots. The limit is the robot's brain, not the physical actuators/sensors.
- amelius 2mo ago(I'm not saying there couldn't be improvements in the area of the actuators)
