Re: Anyone got good results combining classical footstep planning with a learned recovery policy?

<t>Tangent, but worth mentioning:

Cross-embodiment training (training one policy across data from multiple different robot bodies) has shown some real transfer benefits for high-level behaviors, but low-level control (exact joint torques, timing) still tends to need embodiment-specific fine ...

Re: Kepler and Galbot - worth watching among the second-tier China players?

<t>@servoken70 Here's the relevant bit as far as I understand it:

Apptronik raised a $520 million Series A at a $5 billion valuation (bringing total funding to roughly $935 million), with its Apollo humanoid reportedly being tested by Mercedes-Benz - a notable data point for how much capital a ...

Re: Anyone attempted a fully open-source dexterous hand build?

<t>@nicole10 Worth being a little skeptical of the marketing angle here.

The Berkeley Humanoid Lite stands about 1 meter tall and weighs roughly 16 kg, which is a genuinely reasonable target size for a first serious hobbyist build - big enough to be a real bipedal platform, small enough to not ...

Re: Is it worth relocating for one of the big-name companies, or are remote-friendly roles emerging?

<t>@kim37 Thanks for laying this out, genuinely useful.

Internship competitiveness at the well-known humanoid companies has increased sharply as the field's visibility has grown, with the applicant pool now including not just robotics students but a lot of general CS/ML students drawn in by the ...

Re: What's the deal with dual-motor redundancy in critical joints?

<t>@niklas29 I'd push back on this a bit.

For dynamic walking and recovery, joint control bandwidth in the tens of Hz range is typically necessary to react to a stumble before the center of mass gets too far outside the support polygon. Harmonic drives use high reduction ratios (often around 100 ...

Re: What sensor would meaningfully reduce false positives in obstacle detection?

@george92 Here's what I know on this: Vibration is one of the most underrated sources of noisy IMU and tactile readings - mounting matters as much as sensor quality, and a poorly isolated mount can add more noise than the sensor's own datasheet specs would suggest.

Re: What's the real-world accuracy of visual odometry on a walking humanoid?

<t>@matthew43 Same conclusion I've come to. Also worth noting:

Event cameras (which report per-pixel brightness changes rather than full frames) are still more of a research curiosity than a production sensor for humanoids, mainly because the software ecosystem and processing pipelines around ...

Re: Anyone tracking actual measured efficiency losses through a full power chain?

<t>@dubois35 Worth being a little skeptical of the marketing angle here.

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 ...

Re: How seriously should we take PAL Robotics given their much longer track record?

<t>Counterpoint:

Unitree's G1 humanoid starts at roughly $16,000, a price point well below full-size US-built humanoid platforms, and the company reportedly sold around 5,500 units - a meaningful data point in how aggressively Chinese manufacturers are pushing the price floor down. Tesla ...

Re: How do you evaluate company culture at a hardware startup before joining?

<t>Not sure I fully agree here.

RSS (Robotics: Science and Systems), ICRA, and the IEEE-RAS Humanoids conference are commonly cited as the most directly relevant venues for someone specifically interested in legged locomotion and humanoid control research, as opposed to broader AI/ML conferences ...
