<t>Here's the relevant bit as far as I understand it:

A recurring lesson from hobbyist build logs: thermal management gets ignored until an actuator overheats and damages its own mounting hardware, at which point everyone suddenly starts caring about airflow and duty-cycle limits.

Reminds me a ...

<t>Pretty much this. One thing to add:

The market consolidation question (which of the 100+ companies chasing this space survive) is complicated by the fact that hardware is genuinely capital-intensive to scale, so smaller players without a clear cost or technology moat are structurally at risk ...

<t>Not sure I fully agree here.

A whole-body control engineer's day-to-day work is a mix of formulating and tuning constrained optimization problems, debugging why a controller behaves differently on hardware than in simulation, and a surprising amount of time spent on numerical stability and ...

<t>This raises a question for me -

Cycloidal drives are a less common but real alternative to harmonic drives - lower cost at high ratios, decent efficiency, but historically bulkier for the same torque density, which is part of why they haven't fully displaced harmonic drives in commercial hips ...

<t>@gary.tanaka2 Just to be precise about one thing:

Unitree's Dex3-1 dexterous hand packs around 33 pressure/tactile sensors per hand across the fingers and palm, capable of sensing pressure roughly in the 10g-2500g range - a useful reference point for what 'production tactile sensing' looks ...

<t>Yeah, this tracks with what I've read as well.

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 ...

<t>@ronald.clark I'd take that specific number with a grain of salt, honestly.

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 ...

@ananya.novak To answer this directly: 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.

<t>From hands-on experience,

3D-printed gears wearing out is one of the most common early hobbyist failure points - infill percentage, layer orientation relative to load direction, and filament choice (nylon or reinforced composites tend to outlast standard PLA/PETG under repeated gear mesh ...

<t>Slight correction, though the overall point stands:

Transitioning from industrial automation into humanoid-specific roles is a increasingly common and viable path, since a lot of the underlying skills (motion control, safety systems, real-time software) transfer directly, even though the ...
