@_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?
English
@_Stocko_ This is the result after 10mins training, for me it is impressive, immagine do it for real with a real training.
English
The future of agriculture lies in optimization. A system like this costs very little: a drone with a camera and a computer vision system accurate enough to count and identify plants or diseases.
It's so easy that anyone can make it at home for their own crops.
English
@victormustar the cost is all about degrees of freedom. actuators cost a lot
English
Question for robotics people: how far are we from a ~75cm toy robot that can walk and move around okay-ish (bonus points for claw hands) AND costs around $1 or 2k?
Feels like we're technically close, but I haven't seen anything. What am I missing? hardware cost must be the bottleneck?
English
@Booleans_Things i'll keep building robots. my goal is a robot laborer probably working in my yard
English
@_Stocko_ Fast iteration. It's getting close to finished, Then what?
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..
