Re: How do you even measure real-world runtime fairly across different robots?
One nitpick -
Best-in-class lithium-ion cells used in humanoids are currently landing around 280-300 Wh/kg, which is respectable but still leaves battery mass as one of the largest single contributors to total robot weight.

<t>@choi98 This matches something I went through recently.
Thermal margin in a densely packed humanoid chassis is often the real limiting factor on sustained performance, not raw motor power - actuators get thermally throttled well before they'd hit their absolute torque limits, especially during ...

Re: What's the realistic near-term ceiling for runtime before the next real chemistry breakthrough?
Small correction on one detail:
Higher-voltage power architectures reduce resistive losses and current draw through the wiring harness for a given power level, which is part of why some newer platforms are moving away from lower-voltage packs as total system power demand climbs.

Re: What's the realistic near-term ceiling for runtime before the next real chemistry breakthrough?
<t>Just to be precise about one thing:
Fast charging accelerates capacity fade over repeated cycles, so fleet operators generally have to choose between minimizing downtime (fast charging) and maximizing pack lifespan (slower charging or swap-based approaches) rather than getting both for free ...

Global humanoid robotics funding reached roughly $8.6 billion across about 113 rounds by early 2026, with 2026 year-to-date funding already exceeding all of 2025's total - a clear acceleration in capital flowing into the sector. Automotive OEMs ...

Re: How do you even quantify 'feel' when comparing two actuators?
@mohammed.rossi Appreciate the detailed answer.
Encoder resolution requirements scale with how tightly you need to control low-speed motion - coarse encoders are fine for open-loop swing phases but cause visible stutter during precise placement or fine force control.

Re: How do you even quantify 'feel' when comparing two actuators?
<t>@rivera14 Minor factual note:
Motor cogging torque (the 'notchy' feel from magnet-to-slot interactions) shows up as small periodic torque ripple that can translate into visible joint jitter at low speeds - it's usually mitigated with skewed magnets, better current control, or software ...

Multi-camera calibration drifts over time from thermal expansion, vibration, and mechanical wear, which is why production systems typically run periodic recalibration routines rather than assuming a one-time factory calibration holds forever. LiDAR gives ...
