Re: How do you validate depth camera accuracy at typical grasp distances?

<t>@nicole57 Slight correction, though the overall point stands:

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

<t>@greta78 Genuinely curious -

Tactile skin arrays have improved a lot, but 'good enough to matter' really depends on the task - coarse contact detection across a large area is fairly mature, while fine, high-resolution force distribution sensing (like a human fingertip) is still the harder ...

Re: What's the current best practice for safe exploration during real-world RL?

<t>@mohammed64 +1 to this. Worth adding:

'Zero-shot sim-to-real' rarely means literally zero real-world tuning in practice - it usually means the policy transfers well enough to be usable with only calibration and minor safety-limit adjustments, rather than needing a full additional training ...

Re: Anyone using hierarchical RL for combined locomotion and manipulation?

<t>@omar.farouk Minor factual note:

Zero Moment Point (ZMP) control keeps the robot's center of pressure within its support polygon and has been the classical backbone of bipedal walking for two decades - it's robust and well-understood, but tends to produce a somewhat conservative, flat-footed ...

Re: Anyone benchmarking control loop jitter across different onboard compute platforms?

Re: Anyone building grasp datasets specifically for warehouse-style clutter?

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

In-hand reorientation (repositioning a grasped object without setting it down) is one of the more advanced manipulation skills, requiring either a highly dexterous hand with enough DoF or clever use of gravity and controlled slipping - it's an ...

Re: What's the realistic timeline for reliable cluttered-bin picking at human-level speed?

<t>@emily45 I dealt with almost this exact situation.

Underactuated hands (fewer actuators than joints, using mechanical coupling to shape the grasp) are a reasonable engineering compromise for robust power grasps on a budget, but they generally can't do fine in-hand manipulation the way a fully ...

Re: Anyone regret specializing too early before the field's direction was clearer?

<t>@mohammed.rossi Slight correction, though the overall point stands:

A field-deployment or reliability engineer's day-to-day work leans much more toward diagnosing real-world failure patterns, managing spare-parts logistics, and working directly with the customer site than toward algorithm ...

Re: Anyone changed specialization mid-career (e.g. perception to controls) - how hard was it?

<t>@nschmidt This matches what I've seen too.

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 sector's ...

<t>@arjunsanchez +1 to this. Worth adding:

The common academic path into this field is a master's or conversion course in robotics or machine learning, followed by an internship or research role at a known lab or company - a PhD is common but increasingly not strictly required for industry roles ...
