China’s Unitree Robotics is a comparatively latest entry within the general-purpose humanoid robotic house, however its $16,000 G1 mannequin is already proving itself to be fairly the performer. A lot in order that the corporate has now revealed a model that is prepared for mass manufacturing.
Till December final 12 months, robotic improvement at Unitree was just about targeted on producing four-legged robo-beasts just like the Go2 and B2. And by the point the primary biped humanoid made its video debut, there was already stiff competitors from the likes of Tesla, Determine, Boston Dynamics and Sanctuary AI.
However progress has been spectacular, and the US$90k first effort was quickly joined by a less expensive and extra succesful mannequin known as the G1. This one has a visor-like face as a substitute of an air hole and sports activities three-digit fingers the place as soon as have been stumps. It additionally seems to be much less like a improvement platform and extra like one thing headed for manufacturing – and now it seems to be able to make that leap.
Unitree G1 mass manufacturing model, leap into the longer term!
Unitree says that the few brief months since its Could reveal has seen engineers fine-tuning the general-purpose bot to fulfill necessities for mass manufacturing – together with tweaks to its look and enhancements in efficiency. The video demonstrates this by displaying off the G1’s leaping, twisting, hopping and dancing strikes, together with its skill to climb stairs suffering from particles and alter gait in real-time, take varied-height obstacles in its stride, and break right into a jog. It is even proven steadfastly refusing to tumble when confronted with a seemingly vicious assault from one of many dev group.
A fast recap of the given specs does not reveal any apparent enhancements since we final checked in, although the simulated reinforcement studying atmosphere has yielded new methods and improved efficiency. So what we’ve got is a humanoid that stands 1.32 m (4.33 ft) in top and may fold all the way down to 690 x 450 x 300 mm (27 x 17.7 x 11.8 in) ought to an operator want to choose it up and stow it away in a cabinet – although it is fairly a heft at 35 kg (77 lb).
May the G1 humanoid robotic be the house butler we have been ready for?

On its LED-ringed face are 3D LiDAR and a RealSense depth digicam. There’s noise-canceling microphone array included for voice instructions and a 5-W stereo speaker for responses. All cabling is routed internally for clear traces and snag-free operation. A fast-release 9,000-mAh battery is included for round 2 hours of per-charge use. The joints supply 23 levels of freedom in whole and the humanoid can amble alongside at as much as 2 m/s (4.5 mph).
As talked about, pricing begins at $16,000. Unitree describes this newest replace as a mass manufacturing model, although hasn’t confirmed that mass manufacturing is definitely underway. You will discover out extra through the supply hyperlink beneath.
Some months earlier than @robField’s tweet setting off the practice that led to the Eu sensor that discriminates PAP/PAPS, Ed Yates and myself have been having a curry with Dulce Papy-Garcia from UPEC, who had examined considered one of our PhD college students. A matter we mentioned at size was ‘why sulfate’. That’s, why does biology use each sulfate and phosphate to change submit synthesis proteins, polysaccharides and different molecules. We didn’t give you a solution, however the dialog led Ed and myself to contemplate that the query merited exploration.
This we thought can be a easy matter.
It turned out to be one of the tough papers Ed and myself have written, to the extent that after N drafts (the place N is a considerably bigger quantity than both of us had skilled in any earlier writing train) and too many summers we nonetheless had nothing passable. So, we cunningly inveigled two colleagues, Tim Rudd from NIBSC and Marcelo Lima from Keele to hitch us on what we marketed because the sunny seaside of sulfate and phosphate, however which in actuality was a reasonably dank quagmire. There may be although one thing about power in numbers, and with very useful enter from Steve Butler in Loughborough, we arrived at what we thought-about a passable synthesis. Fortunately, the reviewers concurred, and the paper is now printed at Royal Society Interfaces, “Phosphorylation and sulfation share a standard biosynthetic pathway, however lengthen biochemical and evolutionary variety of organic macromolecules in distinct methods”.
That is not at all the final phrase on the matter, however together with some earlier considerate papers we cite (if we’ve got missed one, please let me know) it offers some concepts that will assist us to know why biology co-opted specific parts from the inorganic world to carry out teams of capabilities important to life as we all know it now.
Researchers on the College of Sheffield are exploring new exhaust aftertreatment methods for heavy-duty engines able to operating on clear, zero-carbon fuels resembling ammonia. This four-year venture is funded by an EPSRC grant and supported by the commercial accomplice Eminox. The venture is led by Invoice Nimmo, Professor of Vitality Engineering and Sustainability, with PhD scholar Madhumitha Rajendran.
Background The decarbonisation of transport represents a vitally vital part of world initiatives to minimise the impacts of local weather change. Nonetheless, while the electrification of sunshine autos is a logical manner ahead, heavy autos used within the rail, marine and building sectors have excessive torque necessities which can be unsuited to electrical energy. As well as, diesel engines burn fossil fuels releasing carbon dioxide, a greenhouse fuel (GHG), in addition to different pollution, resembling nitrogen oxides (NOx). Some oxides of nitrogen should not GHGs however they do carry out a task within the formation of tropospheric ozone which is a GHG. Nitrous oxide (N2O) nonetheless, is produced by combustion processes, and is a potent GHG.
Different options are mandatory throughout your entire transport sector, therefore the drive towards clear gas engine growth, alongside new exhaust therapy applied sciences.
New exhaust therapy methods for heavy-duty engines The analysis focuses on ammonia as a clear gas. The primary stage entails modeling twin gas combustion and emission traits of ammonia with a carbon-based promoter. Ammonia requires a combustion promoter due to its larger absolute minimal ignition power than conventional fuels. The second stage of the work will consider the NOx discount efficiencies of economic catalysts for the ammonia-based twin gas, utilising a collection of Sign Group fuel analysers donated to the venture by Eminox.
Why ammonia? Ammonia is taken into account a clear gas as a result of its (full) combustion merchandise are nitrogen and water. Nonetheless, NOx gases are a byproduct of ammonia combustion. Nonetheless, ammonia represents a comparatively good power supply and international infrastructure for its manufacturing and transportation already exists due to ammonia’s function in agricultural fertilizers.
There are a number of kinds of ammonia, every attributed a color in accordance with its manufacturing methodology. Conventional ammonia is named ‘gray’ as a result of it makes use of pure fuel, but when carbon seize is used to take away carbon dioxide emissions, the ammonia is labelled ‘blue’. ‘Inexperienced’ ammonia is made utilizing inexperienced hydrogen, created by electrolysis from renewable power, so no fossil fuels are required.
In distinction with hydrogen, ammonia doesn’t require cryogenic circumstances for transportation as a liquid. Additionally, ammonia might be produced from hydrogen, and ammonia might be ‘cracked’ again to hydrogen after transportation, which implies that ammonia might help resolve the transport points related to hydrogen.
Ammonia presents quite a lot of challenges as a gas for engine combustion. Along with the requirement for a promoter gas, these embody NOx within the exhaust in addition to ammonia slip, which is vital as a result of ammonia is each corrosive and poisonous, and since unburned gas represents inefficiency.
Analysis section 1 – Twin gas combustion modelling Preliminary work is being undertaken with ‘Ansys Chemkin-Professional’ a chemical kinetics simulator program that fashions idealised reacting flows and gives perception into outcomes. Madhumitha has been utilizing the modelling program to research predicted results on engine effectivity and emissions profile, by adjusting quite a lot of totally different variables, resembling stoichiometry, gas power shares, and gas injection parameters. The outcomes of the modelling are getting used to tell subsequent work.
Analysis section 2 – Submit-combustion therapy The second section of the analysis, which is because of start on the finish of 2024, will consider the NOx discount efficiencies of commercially accessible selective catalytic discount (SCR) supplies beneath a variety of various circumstances. Three totally different SCR catalysts can be trialled, based mostly on zeolite, vanadium oxide and titanium.
The analysis laboratory in Sheffield incorporates a managed temperature furnace reactor utilizing simulated exhaust gases. Catalyst research can be carried out at Sheffield whereas companions at Brunel College in London can be conducting related work with a diesel engine check mattress; primarily to research combustion and gas injection points referring to ammonia gas, but in addition to assist confirm exhaust fuel composition beneath a variety of circumstances. Mixed with the kinetic simulation work at Sheffield, life like exhaust fuel composition can be fed to the experimental reactor.
Fuel evaluation The submit catalyst exhaust gases can be analysed by the Sign Group analyser rack, after therapy by the catalysts. This instrumentation features a heated vacuum chemiluminescence fuel analyser for the measurement of NOx, NO and NO2. A flame ionisation detector to analyse hydrocarbon ranges, and a non-dispersive infrared multi-gas analyser for steady measurements of carbon monoxide and carbon dioxide. This instrument can also be fitted with an oxygen sensor.
Preliminary outcomes Thus far, modelling work has indicated that using an ammonia twin gas may enhance
N2O emissions beneath sure working circumstances, significantly in chilly begins. Exhaust fuel temperature will cut back, whereas moisture and hydrogen ranges might be anticipated to extend, and the results of this on SCR catalyst deNOx effectivity can be studied additional.
The mannequin additionally confirmed that the utilisation of ammonia twin gas has quite a lot of implications for potential SCR catalysts. For instance, ammonia within the exhaust might help cut back NOx, and each hydrogen and hydrocarbons within the exhaust can improve NOx conversion at average temperatures. Nonetheless, N2O can be troublesome to decompose at low temperatures. By figuring out regimes of operation and emissions, suggestions might be made on catalyst specification and working circumstances to mitigate any operational points.
Abstract The event of fresh gas expertise can be critically vital to the decarbonisation of heavy autos. For instance, the Worldwide Maritime Organisation (IMO) has a GHG emissions discount technique to achieve net-zero by 2050, together with a 20% discount by 2030 and a 70% discount by 2040, in comparison with 2008 ranges. To achieve these ambitions, the IMO will implement regulatory measures to be adopted in 2025 and enter into power round mid-2027. The achievement of those decarbonisation objectives will rely closely on using carbon-neutral fuels. This, in flip, implies that new engine expertise can be mandatory, working effectively beneath recognized stoichiometric circumstances, mixed with efficient aftertreatment methods to make sure the discharge of non-toxic, climate-friendly emissions.
Madhumitha explains, “The problem for the venture is to contemplate the minimisation of all doubtlessly dangerous emissions from new fuels, and we can be maintaining a detailed eye on any N2O, NOx and ammonia when creating the brand new SCR methods. Nonetheless, the profitable achievement of our objectives will play an vital function in serving to the heavy car sector to scale back its GHG emissions, so we’re vastly excited concerning the prospects for this vital venture.”

12 Aug 2024 • , 5 min. learn
Individuals have been shopping for and promoting gadgets on Craigslist for almost three a long time. As a platform for digital labeled adverts, its utility continues to be second to none for many individuals. However its simplicity (and anonymity) may create dangers which might be, in lots of respects, equal to, if no more acute than with, these on on-line marketplaces reminiscent of Fb Market.
Certainly, there’s little in the way in which of safety from scammers, who may promote you gadgets that don’t exist or attempt to harvest your private data to be used in follow-on fraud. Alternatively, they might attempt to purchase gadgets you’re placing up on the market utilizing fraudulent fee strategies.
It pays to remain conscious of each outdated and comparatively new tips they’re utilizing to take action. Look out for the next warning indicators.
Frequent Craigslist scams to keep away from
1) Non-existent gadgets
There’s an entire class of Craigslist scams that revolve round a fraudster claiming to promote one thing they don’t have of their possession. It could possibly be a ticket to a present, a automobile, a pet, an condominium or vacation rental, or perhaps a job itemizing. They’ll normally draw victims in by both creating a way of urgency (i.e., a ‘final likelihood to purchase’ a sold-out gig ticket) or by promoting an merchandise for a lot decrease than its face worth.
Be alert to those warning indicators, solely pay for gadgets through safe fee strategies, and by no means pay for a high-value merchandise earlier than seeing it in individual first (together with property leases).
2) Overpayment
A purchaser sends you a examine for an merchandise, but it surely’s for greater than the acquisition quantity. They urgently request you pay them the distinction through wire switch or an analogous methodology. Nevertheless, within the meantime, the examine bounces, leaving you out of pocket.
Refusing to share any private or monetary data in your communications with sellers and consumers
Utilizing disposable telephone numbers and e-mail addresses so that you simply additional defend your major contact data. (Craigslist makes use of two-way e-mail relay to cover your e-mail deal with when speaking with consumers or sellers).
In case you received scammed on Craigslist
Within the occasion of a worst-case state of affairs, maintain calm. Contemplate the next:
Report the rip-off to the FTC (in the event you’re based mostly within the US) and/or the FBI’s Web Crime Grievance Middle
Hold an in depth eye in your financial institution and credit score accounts and flag if there’s any suspicious exercise
Inform Craigslist that the itemizing was a rip-off, by clicking on the purple flag icon and submitting a report
File a report with the police
Craigslist generally is a nice useful resource. However the worth we pay for comfort is having to navigate the darker facet of the digital world. Keep protected.
