Meet Robo!

i'm in the very early stages of building an accessible, general-purpose robotics platform, and looking for a few passionate people to help shape it from ground up. if you'd be excited about moving fast on a small, hands-on team I would love to chat -- my DMs are open!

(demo is teleop, 1x speed)

@___Harald___ @marcospereeira this might be cope but i do think the loss landscape from 1990 to 2020 had a lot less 'fog of war' than todays world (US maintaining global geopolitical/financial stability + obvious tech tree to climb)

[Vrushank Desai @vrushankdes]

@YuXiang_IRVL i've been wondering the same, i think we will soon run into hard limits of what the hardware can do bc robot hands/tactile sense sucks. the switch from software to hardware as bottleneck came faster than i expected

[Vrushank Desai @vrushankdes]

@chris_j_paxton i'm interested in seeing how this bet plays out but i am sorta bearish in the long-run. i think they rely heavily on expensive robots with harmonic drives to stay in-distribution with UMI data but ideally the policy can just handle cheaper arms that have backlash (ALOHA/ARX)

@phethers ooh ive never tried flux on the wick, thanks!

[Vrushank Desai @vrushankdes]

@lukebayes @phethers hmm i was having issues around 350C, i'll try a bit warmer and a wider tip, thanks!

[Vrushank Desai @vrushankdes]

@xiao_ted OK wow, just saw the paper. very impressive if the model generalizes without explicit alignment!

[Vrushank Desai @vrushankdes]

@xiao_ted is the output action space joint angles or end-effector position and is an overhead camera view part of the input? asking because UMI-style data collection can lead to 'motion generalization' but its more of a property of the IK-solver + standardized camera views/action space

it terrifies me how many talented people are contributing to a future they wouldn't want to live in. building something addictive. exploitative. destructive. something they'll ban their own kids from using. and for what? a paycheck? surely there's a better way to use your gifts?

[Vrushank Desai @vrushankdes]

@JimDMiller @Leo_Abstract @subygan @dwarkesh_sp @gwern i think bipedalism + hand is extremely underrated. an elephant's ability to channel more intelligence into evolutionary fitness is pretty bottlenecked by lack of appropriate end-effectors. whereas humans could write/dig and plant seeds/use spears/etc

@MechanizeWork dont take the bait guys dont do it

Even if you wrapped the entire planet in a solar panel, you would only be producing 20% of global energy.

One of the biggest mistakes politicians can make is equating the ELECTRICITY with ENERGY!

humans are so cool, man

bunch of apes walked out the jungle and went to the moon and made the sand think

crazy fucking apes

americans wouldn't have such a strong distaste for silicon valley if any of you were willing to stand up for principles. but alas, you haven't vested yet have you

@faraz_r_khan have you tried V-blocks?

@jachiam0 mundane long-tails that accelerate day-to-day progress are still rough. for example, today gpt-5 web-search just hallucinated a handful of phone numbers for city food departments. when this is marketed as "Death Star Phd-intelligence" it can be frustrating...

worth a read!

[Vrushank Desai @vrushankdes]

@willdepue @rationalaussie statement feels disingenuous considering how much effort is put into curation/expert dataset creation.

consider a model pre-trained on everything from the internet OAI chooses to leave out of the corpus (SEO/auto-generated logs/etc). is that going to work well?

[Vrushank Desai @vrushankdes]

@ErebiusWhite certainly a lot of scams would be exposed. like trying to trade powerpoint consulting services for a house and groceries...

money is a dangerous abstraction
