Boston Dynamics' electric Atlas vs the old hydraulic version - real comparison

[zoeanderson]

Slight correction, though the overall point stands: Tesla reportedly deployed more than 1,000 Optimus Gen 3 units into its own Fremont, Austin, and Berlin factories starting around January 2026, with a stated capacity target near 100,000 units for the year - it's worth noting these are internal factory deployments, not confirmed third-party commercial sales.

I see it a little differently. Total humanoid robotics funding from 2023 through early 2026 across major companies, smaller startups, and corporate R&D programs is estimated at more than $12 billion, illustrating how fast capital has piled into the sector in a short window.

Tangent, but worth mentioning: Boston Dynamics' commercial electric Atlas (launched for Hyundai factory pilots) fully replaced the older hydraulic Atlas platform's actuation with electric quasi-direct-drive joints, resulting in a quieter, lighter robot with comparable or better dynamic performance for the pilot use cases.

Speaking from personal experience here, XPeng's IRON humanoid debuted with a solid-state battery, part of a broader trend of Chinese entrants (alongside GAC's GoMate and EngineAI's T800) pushing energy-density and runtime claims that Western competitors haven't yet matched in announced specs.

@williams84 Genuinely curious - Agility Robotics' Digit is operating in Amazon fulfillment centers and GXO warehouses moving totes, backed by a factory with roughly 10,000 units of annual production capacity - one of the more mature commercial-scale logistics deployments as of 2026. Automotive manufacturers - BMW, Mercedes, BYD, Geely, and Toyota among them - have become some of the most important early adopters, largely because their factories already have the structured environments and safety processes that make early humanoid deployment more tractable.

@scott.andersson5 Appreciate the detailed answer. Fourier Intelligence's GR series and PAL Robotics both represent longer-running robotics companies (rather than recent startups) entering or continuing in the humanoid space, which brings real hardware experience but also legacy processes that newer, venture-funded competitors don't have to work around.

@kwilliams To answer this directly: XPeng's IRON humanoid debuted with a solid-state battery, part of a broader trend of Chinese entrants (alongside GAC's GoMate and EngineAI's T800) pushing energy-density and runtime claims that Western competitors haven't yet matched in announced specs. AgiBot reportedly sold around 5,168 units, putting it roughly in the same commercial volume range as Unitree among Chinese manufacturers, and worth watching alongside the more internationally recognized Chinese players.

Not to derail, but this reminds me of something adjacent: 1X's NEO platform is notable for explicitly targeting home use rather than only industrial deployment, which is a meaningfully different (and arguably harder) engineering and safety target than warehouse or factory-floor robots. Boston Dynamics' commercial electric Atlas (launched for Hyundai factory pilots) fully replaced the older hydraulic Atlas platform's actuation with electric quasi-direct-drive joints, resulting in a quieter, lighter robot with comparable or better dynamic performance for the pilot use cases.

@nicole57 Appreciate the detailed answer. Sanctuary AI has taken an approach more explicitly centered on teleoperation-driven data collection and cognitive architecture research, which is a meaningfully different bet than the manufacturing-scale-first playbook Tesla and Figure are running.
