<t>@matthew.yamamoto0 I see it a little differently.

Insurance and liability frameworks for humanoids working directly around people are still immature in most jurisdictions, which is a real, under-discussed constraint on deployment speed that gets far less attention than the flashier technology ...

<t>I dealt with almost this exact situation.

Quasi-direct drive (QDD) actuators use lower gear ratios (roughly 6:1 to 10:1) paired with high-torque-density motors, trading some peak force density for backdrivability and low reflected inertia, which matters a lot for impact tolerance and fall ...

<t>@thomasmitchell I'd frame this differently.

Vision-Language-Action (VLA) models like RT-2, OpenVLA, and Physical Intelligence's pi0 unify a vision-language backbone with an action-output head, letting a robot map a camera image and a text instruction directly to motor commands instead of hand ...

<t>@mohammed.rossi I see it a little differently.

Distributed power architectures (multiple smaller packs or local capacitor buffering near high-draw actuators) can reduce peak current demands on the main bus and improve fault isolation, at the cost of added complexity versus a single central ...

<t>@kwilliams Counterpoint:

Idle/standing power draw is often surprisingly close to a meaningful fraction of active walking power draw once you account for onboard compute, sensors, and balance-holding torque - 'doing nothing' still costs real energy on a humanoid. Higher-voltage power ...

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

Estimated total operational commercial humanoids worldwide sit around 7,000-8,000 units as of mid-2026, broken down roughly as Optimus Gen 3 (1,000+), Unitree (5,500+ cumulative), Agility Digit (~250), Apptronik Apollo (~80), and ...

<t>Ran into exactly this myself.

Jetson-class boards remain a common choice for onboard compute on hobbyist builds needing real vision or learned-policy inference, while a Raspberry Pi is often adequate for lower-level joint control and telemetry if the heavier compute is offloaded to a base ...

<t>@servoken70 Appreciate the detailed answer.

A realistic hobbyist bill-of-materials for a small biped balloons fast once you add a real IMU, decent motor controllers, a reasonable battery/BMS setup, and enough compute for onboard control - the headline '$5k' budget assumes a fair amount of DIY ...

<t>@olga24 Agreed, and I'd add:

Unit economics for an early fleet deployment have to include maintenance, downtime, and technician support costs, not just the sticker price of the robot - a lower unit price (like Unitree's roughly $16k G1) doesn't automatically mean a lower total cost of ...

<t>@carol.robinson Small correction on one detail:

Companies like Figure, 1X, Apptronik, and Agility Robotics are reportedly pulling senior ROS, controls, and learning engineers directly out of warehouse-automation and industrial-robotics roles - a sign of real talent competition between adjacent ...
