i'm obsessed with these MIT Maker Portfolios
this is the best one i've ever seen. this is real engineering.
how does he only have 3 followers?
Ethan built:
01. omni-directional wheels / swerve modules
02. a mechanical integrator that does calculus with moving parts
03. a polar plotter that can draw all sorts of wild patterns
04. a modded Ender 3 that he turned into a CoreXY claw machine
05. a cycloidal gearbox
06. a 5-axis 3D printer and slicer inspired by Joshua Bird's 4-axis design
now he's working on a compact, battery-powered, ultra-portable expanding 3D printer
a body of work like this usually takes a full team years
Ethan did it before college
this guy is an absolute machine
if anyone deserves more support, itβs him
I built this portable 3d printer. it folds flat, and a scissor lift lets it expand to print big objects. It's CoreXY, uses fishing line for the motion system, has a direct drive extruder, and the option of storing an 8-hour print time battery or an entire filament spool inside
A new Chinese robotics startup, Light Origin, just showcased an impressive single-policy locomotion system.
Even with one or both legs restrained, the robot remains mobile by hopping or crawling.
generalist's hardware team doesn't get enough credit for their creativity. compliance is in the tool mount. qdd-like contact tolerance, harmonic drive precision, and the deflection is readable on camera because of how it's shaped and colored. no f/t sensor per tool, so cool
We trained a dexterous hand π€ from internet-scale human videos πΊ with ZERO real-world robot or teleoperation data
We pair a world model π that predicts task intent with a generalist sensorimotor policy β trained sim2real to zero-shot fulfill ANY intent

Scott Wu says coding was never the point, the interface is.
humans telling computers what to do. and the most natural interface anyone has is texting.
so Cognition went and bought Poke, the agent that lives in iMessage. 100M messages in three months.
Scott and Walden were early angels in it. this was likely the plan for a while.
makes more sense once you hear him lay it out.
