@peteoxenham the funniest outcome is that you and i spent three years evangelizing machining and yelling about 3d printing on twitter... to end up making the next benchy

@cixliv Yeah for sure, but I mean at this time stamp the robot could have easily broken the guys leg. Unless they’re doing some movie magic and recording robot and human separately and superimposing.

@Mattbalisky I will say the robot mimicking the persons movements is fake, you pre train it. but the movements themselves are real

@cixliv I still don’t believe they would have someone doing mirror movements that close to a robot that can do that but 🤷‍♂️ At one point their feet are like maybe a foot apart? anyways wild video if real

Can’t agree more. I constantly say we have not seen the blackberry of humanoids yet, and we are far away from the lovely thing we all keep in our pockets today. Agree the rate of change will also be very accelerated. Mass adoption of home robotics is far off… much further than industrial
vittorio@IterIntellectus

i hope people realize that NEO is the Motorola Dynatac of humanoid robots they will get much better, smarter, faster, and cheaper. it will also happen much faster the sci-fi future is here and it’s going to be glorious

@benjamin_bolte What is the highest level of assembly you will be getting from China? Or cutting out of supply chain entirely? E.g. assembled limbs vs assembled actuators vs motors vs laminations

FYI, the GOOD news is that there are a lot of great, highly-capable manufacturers who would ALSO like to avoid Unitree wielding monopolistic supply chain power. Go talk to anyone who has ever manufactured hoverboards, electric longboards, VR headsets, etc. - they are incredibly skilled at competing on margin, with low idiot indices. And they're actively investing hundreds of millions of dollars in manufacturing in American right now. There is an alternative path, for people with the guts to walk it. This path will not be available for long.
Benjamin Bolte@benjamin_bolte

About a dozen people sent me the Unitree announcement today. Makes sense, since I guess since K-Scale is the only American humanoid robot company with a product that you can actually buy. If you are American and you care about the future of robotics in this country, you should ask yourself - do you want to surrender the future to Unitree because you'd rather make excuses than win? What does a world with millions of Unitree robots look like? Unitree is not selling these robots at a loss. In fact, their margins are likely very good, even factoring in tariffs. They are just a good company making a great product in a market with no incumbents. And while Figure and Tesla are cutting their production volumes (because, to the surprise of no one with half a brain, no one wants an expensive, useless, vendor-locked humanoid robot), Unitree is ramping up, building massive supply chain network effects that will make their robots even cheaper and better quality, while also growing their in-house software team like crazy. For anyone who does not live in Silicon Valley, you should also know that yes, Silicon Valley is asleep at the wheel. Basically no one here doing robotics has ever actually made a robot or stepped foot in a factory, much less sold a consumer electronics product or deployed an AI model in a real production environment. The best funded companies have anemic hardware teams that are basically just modding Chinese bots, or are dumping insane amounts of money trying to cobble together expensive in-house hardware with zero direction. The future of this country's robotics industry is a dozen "foundation model" companies training the same model architectures on the same Chinese robotics datasets, all burning money on GPUs to create value for Unitree, pretending that they will magically achieve cross-embodiment transfer with another $100m investment, while pushing back delivery timelines until after they can get acquihired by OpenAI or Google. Fuck that. Tariffs on China are at all time highs, and everyone is still competing for the American market (why do you think Unitree's robot is red, white, and blue?) American robotics companies should be playing on easy mode - what are tariffs even for otherwise? Why complain or call Unitree cheaters? Just make something that people actually want to buy, and respect the awesome engineering that Unitree is doing. Any other attitude is fucking un-American.

@TheHumanoidHub What is the application for more miniature Chinese humanoids, I think Unitree and booster have won this market

@parthingle_x There is no axial constraint on the outer races unless I’m missing that feature. Also is everything just press fit together? There will be some case of tolerances that makes the bearing inner races be free as well without knowing your tolerance stack.

@Mattbalisky I modified the bore in the rotor to have a lip that touches the inner race of the top bearing. The rotor, shaft, and the inner race rotate in the same direction so I don't think there's any sliding contact (please correct me if I'm wrong).

New test on motor was so bad it’s genuinely embarrassing. The bottom housing was already wobbling and pushed the stator, rotor, rotor shaft, and the shaft bearing out within seconds of running

The no fucking around bearing arrangement for DGBBs is fixed, free. One of the bearings is fixed on all four corners and the 2nd bearing is axially free on one of the races, that race should be a slip or transition fit with the housing/shaft. If there is significant thermal effects to be expected you can make the interface with the free race to be a steel insert so the sliding contact is steel on steel. Having the bearings actually preloaded by wave spring or some other compressible media is always a good idea :)

@Mattbalisky Also probably should increase the diameter of the bottom encoder magnet holder screw to act as a defacto retaining ring

The Unitree G2 won't be making ads for Volvo Truck anytime soon The 45 deg anhedral hip means the abductor (green) passes through the singularity (red/blue align) at 45 deg of abduction. Only halfway to this most epic of splits Jean-Claude Van Damme's job is still safe. For now
