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

<t>@james15 Short answer:

Estimating joint torque from motor current draw is cheap and requires no extra sensor, but it's less accurate than a dedicated torque sensor because it doesn't capture friction losses through the gearbox - good enough for coarse control, not always for precise force ...

Re: What's your prediction for the market leader by unit count in two years?

<t>@matthew.watanabe I don't think that's quite right, for what it's worth.

Sanctuary AI has taken an approach more explicitly centered on teleoperation-driven data collection and cognitive architecture research, which is a meaningfully different bet than the manufacturing-scale-first playbook ...

Re: How much of the valuation is the hardware vs the software/data moat?

<t>I dealt with almost this exact situation.

Q1 2026 alone saw about $2.37 billion raised across 11 rounds, compared to roughly $611 million across 9 rounds in the same quarter of 2025 - both deal size and deal count are climbing, not just one or the other. The market consolidation question ...

Re: Anyone benchmarked tactile sensor response time under rapid contact?

<t>Minor factual note:

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. Latency between a perceived ...

Re: What's a good beginner sensor fusion project before tackling a full robot?

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

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 ...

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

@rossi30 Ran into exactly this myself. 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: Anyone tried fully passive compliant fingers with no active sensing at all?

Agreed, and I'd add: Palm sensing gets less attention than fingertip sensing, but a lot of power grasps (holding a box, a tool handle) rely more on palm and lateral finger contact than fingertip contact, so under-sensing the palm can leave a real blind spot in grasp confidence.

Re: Anyone measured actual battery degradation after a full year of daily cycling?

<t>@young56 Genuinely curious -

Solid-state battery claims from platforms like XPeng's IRON, GAC's GoMate, and EngineAI's T800 are genuinely promising on paper for energy density and safety margins, but independent, large-scale field validation of those runtime claims is still fairly limited as ...

Re: What's the realistic gender/diversity picture in robotics teams right now, honestly?

<t>@brenda52 From hands-on experience,

A whole-body control engineer's day-to-day work is a mix of formulating and tuning constrained optimization problems, debugging why a controller behaves differently on hardware than in simulation, and a surprising amount of time spent on numerical stability ...

Re: How do you evaluate whether a startup's equity offer is realistically worth anything?

<t>Appreciate the detailed answer.

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 industries, not ...
