@_Stocko_ What motors does this use?
English
here's a new top that gives an extra 3mm of clearance
Stocko 🦾@_Stocko_
it doesn't fit all the way. there isn't enough clearance for the wiring. i should have tested this before soldering the battery tabs..
English
@_Stocko_ What hardware did you use for the battery contacts and can a nigga buy 1000 if them?
English
@_Stocko_ I know @BillyZelsnack had built something like that!
English
does anyone remember the account that was building a robot with motors in the torso and driveshafts down the arms? i think it was sometime last year or maybe 2024..
Stocko 🦾@_Stocko_
i've seen some attempts here on X to do this with a robot (one motor robot), but it ended up with crazy gearing and shafts and stuff. i can't find the account so here's the armatron's drive gears
English
@patrickdoddboy true but i believe they had each selector drive a dof, like forward/back. so you could drive the arm going up and the wrist spinning at the same time
English
@_Stocko_ I like thinking about this stuff but I think electric motors are just so simple, cheap, and powerful that there will just be motors everywhere and it will be fine.
English
@hawkngradiation yeah, but it didn't have to be. i think it was slow because it was a toy. low torque motor, plastic gearing, alkaline batteries, etc.
English
@Oahu5nackbar yeah, that's the idea. it's like a hybrid between a fully mechanical thing like the armatron and fully electric one-motor-per-dof like most robots are these days
English
@_Stocko_ Same thing but more localized and less complicated isn't it?
English
@patrickdoddboy the armatron actually does drive multiple dofs at once, but loses torque of course. which could be compensated for in the joint model i think..
English
@Oahu5nackbar someone has tried that and it was hard to pull off. i'm talking about keeping the mechanical wizardry in one area and make a 3dof joint out of 1 motor
English
@_Stocko_ One central prime mover in the torso and a series of clutches and gear trains driving everything.
English
also I was thinking about this robot more how the shoulders and hips are essentially 3dof joints. 12 actuators just in the hips and shoulders

A new robot enters the scene: LEJUrobot The head, shoulders, hands, torso, and legs are all following the rhythm, but this is still a controlled demo space. It shows mechanical maturity more than realworld usefulness. That is the gap in humanoids right now. Polished motion gets attention. Reliable behavior outside the booth is the harder proof. Should humanoid companies show more raw testing footage, or are public demos still the best way to measure progress?
