Re: Anyone measured real-world tactile sensor degradation over months of use?

<t>Genuine beginner question -

SLAM in a working warehouse is harder than in a controlled lab mainly because the map keeps changing - pallets move, people walk through, lighting shifts near dock doors - so a lot of production systems lean on semi-static maps refreshed periodically rather than ...

Re: What CAD software are people actually using for their builds?

<t>New to this, so forgive me if this is obvious -

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 ...

Re: What's the biggest skill gap you see in new grads applying to robotics roles?

<t>Sorry if this is a basic question, but

Remote work remains genuinely limited for most hands-on humanoid hardware roles, given the need for physical access to robots and test environments, though software-only roles (simulation, perception algorithms, offline learning) increasingly do offer ...

Re: Anyone using simulation-only training for grasp policies with zero real data?

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

Tendon-driven fingers let you move the heavier actuators back into the palm or forearm, keeping the fingers themselves light and fast, but they introduce cable routing, tensioning, and long-term wear problems that direct-actuated fingers don ...

<t>Not to derail, but this reminds me of something adjacent:

Re: Anyone tried fully passive compliant fingers with no active sensing at all?

<t>@kwameivanov Appreciate the detailed answer.

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: What's your actual weekly time commitment to keep a solo build moving?

<t>Sorry if this is a basic question, but

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 ...

Re: Anyone built custom PCBs for motor control instead of buying drivers?

<t>Sorry if this is a basic question, but

UC Berkeley's Berkeley Humanoid Lite is a genuinely open-source, roughly $5,000, 3D-printable humanoid - structural parts print on a standard desktop printer (around a 200x200x200mm build volume), with CAD files, parts lists, assembly instructions, and ...

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

<t>I dealt with almost this exact situation.

Robotics engineers in the US were reportedly seeing $150k-$205k total comp at mid-level and $205k-$300k at senior level in 2026, with humanoid- and foundation-model-specialist roles clearing $280k-$475k - a meaningful premium over general robotics ...

Re: What's your take on humanoid robots getting their own trading cards/hype culture online?

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

The 'humanoid' form factor mostly wins on infrastructure compatibility, not raw efficiency - stairs, doors, and tools were all built for a human body plan, so a legged, two-armed robot slots into existing spaces without ...
