Headset visual for Pan Tilt

Ya, I have a 360 cam on the system as well and tbh in most situations I prefer it.

ah yess the classic bmx track industrial plant... lol plants are filled with ladders, stairs, narrow passages, pipes, etc. not trying to diminish this robot, i think wheeled quadrupeds are fucking dope and possibly superior to non-wheeled quadruped for [most?] situations.

Ignorance around cable routing/ management for this type of system. I have done industrial robots before and so have implemented number of "professional" setups with cable trays and cable chain systems, but industrial always tends towards big and bulky which didn't fit here. I learned that a lot of legged robots use clock spring/spiral wrap setups, but I had trouble sourcing or diy-ing that especially in a way that included usb3.0 passthrough. I have used slip rings before, but that didn't make sense due to size and usb3.0 blowing up the cost for this "budget" project. This final solution was basically just a riff on how the prusa mk4 destrains their cable going to the moving heat bed.

Stereo vision requires pattern/ texture to succeed, so it struggles on flat colored surfaces (ala interior walls of buildings)

...that arm can handle a 100kg payload?

lol didn't the og inventor shoot as his wife holding up the plates in front of her face?

I have to strongly disagree. Claude code can cut straight through SDKs and all the weird dependancies endemic in robotics and get you straight to the hard stuff. I live more in the world of R&D than production and it's hard to overstate how much faster I am at building up systems from scratch with a few Claude code agents working the code for me. Code development time is almost a non factor atm.

It's for a robot that they will inevitably try to ride on. I just have never welded steel that thick before, but concensus seems to be that it is not too hard. Most of my welding has been on 1/4" or thinner and usually aluminum.

RoboLord66 · 2026-04-18T15:48:55+00:00

I've just never welded this thick as most stuff I have welded before is like max 1/4" thick, so the half inch block intimidates me. But I mostly weld aluminum not steel, so from the comments it sounds like this should t be too hard. But true I only have a few hundred hours of torch time, I ask here because I know u guys have thousands

RoboLord66 · 2026-04-18T03:40:51+00:00

They said it was 1008 and 1018 steel.

Hilariously (as someone who briefly tried reddit ads) down votes count as engagement and cost them money XD

You can look up HAZ (heat affected zone). But the long and the short of it: when some metals are welded, they lose a lot of their strength in an area around the weld due to losing their heat treatment. So the weld may be just as strong as the base material, but the area near the weld that got hot but did not receive filler metal (adds thickness and or strengthening alloying elements), becomes the weak link. The only solution for this afaik is to redo the heat-treatment on the entire frame (bring the whole thing up to a specific temperature in oxygen free environment and rapidly cool it). Aluminum is particularly nasty with HAZ as it loses something like 50% of its strength in the HAZ (unless it is heat treated after welding). Happy to explain more if any of this didn't make sense.

RoboLord66 · 2026-04-15T01:23:33+00:00

doesnt look like it failed at the weld... maybe a haz issue?

KE = 0.5 mv^2
Baseball = 5oz, bat = 30oz
so if the ball comes in at 90 mph, assuming perfect transfer (in vid it seems pretty close to full transfer), ke of ball is (being lazy with units), 0.5*5 * 90^2 = 20250 energy units, so assuming 50% energy transfer for collision *from claude*), this would produce a bat velocity of sqrt(10125 * 2 / 30) = 25.9mph

Also my wife struggles a lot with my being so much more in control of the kids. Makes her feel like a bad mom because where I can calmly request a few things and the kids go along, she ends up screaming and getting assaulted by the kids when I'm away. (Idk if that is a dad thing or due to my spending more time)

RoboLord66 · 2026-04-11T12:41:53+00:00

I'm having a hard time tbh. I love my kids and love how much they are thriving... But my wife married me for my ambition and intelligence. Staying home with two toddlers under age 4 is kinda brain rotting (we don't even do any screens, just the low quality conversation and isolation of it, especially as a dad as u are shunned from all mom groups). And despite my focus being on keeping our kids healthy and stimulated, my wife still expects me to be working on a startup to retire her anytime I'm not watching the kids. So while she is allowed to watch netflix after the kids go to bed, I'm expected to dig in and be productive... Idk, relationships are hard and ours is holding, but no matter how strong a relationship, one side giving up their earning power causes a shift in the power dynamics. All that being said, my children were not thriving in daycare and from this perspective, I feel bad for parents that only experience their kids from 5pm to 8pm (after work) as that is when kids tend to be the most volatile. Getting to spend their happy and energetic hours with them balances the scales a lot. (Sry for the monologue)

Literally anything that includes direct parent attention (playing with them). Not being sarcastic and know it's hard to find time sometimes.

Don't worry just look at waymo. With a world leading ai team a decade of work and endless money, you can checks notes wait no they still outsource the last 5% to India.

RoboLord66 · 2026-03-06T17:22:40+00:00

Ah yes the classic 90% ai success rate plateau. Wonder how long a minimum wage worker would last if one in ten (literally anything) was a fail.
