There is an autism lottery. Either you're autistic about something totally monetarily useless like sonic speedrunning, or you are autistic about something that makes a fuck ton of money like GPU schedulers

@TakaM0331 they're doing PhDs out of anything now

Excited to present our rat exoskeleton at ICRA 2026! We developed what we believe is the first rodent exoskeleton designed to support the entire rat hindlimb (thigh, shank, and foot). Our goal is to provide a new robotic platform for neurorehabilitation research. #ICRA2026

@fishPointer show pls

spider webs in a vacuum chamber top 5 most beautiful thing i've ever seen

Shoulder movement, just the spherical joint. Ah so much to do still.

Rough idea of where i'm going, pitch/yaw drives pulling spherical joint at fixed positions and the roll drive making the whole inner structure of the joint spin within a large bearing. Have yet to figure out cable redirection and constant feed rate to keep the cables tensioned.

@zackslab codec optimized for common video? 🤷‍♂️

idk why x video compressed the shit out of this... actually looks much better on my desktop.

event sensors are wild. they output asynchronous pixel change events rather than a global or rolling shutter dumping entire frames. this allows for a pseudo high frame rate (10k fps). going to see if i can track bullets in flight. will update soon.

So, I have two test users and needed a guide - so I made a System Help/Guide for my Operating System. This has sound, so sound on! All in C/C++, & some light HTML for pages. The voice took a lot of work to get right (imho agents *should* sound like this)

@ShimazuSystems uh, must be for a specific research topic

?????

@distributedkv check

dear algorithm, show this tweet to people who are wizards

@XiaomiZhaWei It's alright, a cave with a box of scraps should do.

@exalbur That looks like high production costs ☝️😐

V2 of spherical joint WIP, it is STRONGER and has WIGGLE arcs to avoid obstructions. 🤠

@Wtjnsgnsmegjek the children (my robots) yearn for a true shoulder (parallel 3dof hemisphere joint)

@exalbur A simple X + Y axis joints should have done the trick! Y + Z even! If you care about durability you can make the joints bigger. 😂It'll cost a hundred times more just to have this part

@PavsProjects @_Stocko_ Tan and transparent parts are bearings i ordered, the light and dark grey parts are 3D printed PC blend carbon fiber but thinking about making those from metal in the future.

@exalbur @_Stocko_ What’s it meant to be made of?

@velismo This is Onshape, works as well as your internet connection.

@exalbur nice! what software is this?

x.com/i/trending/204… can it already rotate shapes with mind? no? ah maybe next time

@shiri_shh the vampires won't like this one

This startup lets you ORDER SUNLIGHT from space to your exact location in 30 seconds 😭
