Re: Anyone else skeptical of self-reported 'production units' numbers?

<t>@ethan.lewis5 This is a great summary, thanks.

Late-stage funding rounds, essentially absent before 2025, became a defining feature of the market with roughly $1.1 billion raised in 2025 and about $2 billion in 2026 year-to-date - a sign investors increasingly see specific companies as de ...

Re: What's a reasonable service interval for a commercial-grade joint actuator?

Respectfully, I think this undersells it a bit. Series elastic actuators add a spring element in series with the drivetrain, which gives cheap, precise torque sensing (measure spring deflection) and passive shock absorption, at the cost of reduced control bandwidth and added complexity.

Re: What torque sensor accuracy is actually achievable at low cost?

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

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 ...

Re: Best practices for IMU-to-camera extrinsic calibration on a moving robot?

<t>Follow-up question though -

Proprioception (the robot's sense of its own joint angles, velocities, and forces) tends to get less attention than flashy vision systems, even though a lot of balance and manipulation failures trace back to proprioceptive noise or miscalibration rather than a ...

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

<t>@deborah59 Ran into exactly this myself.

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 ...

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

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

Sensor fusion mostly earns its keep by covering for each individual sensor's weaknesses - vision struggles with occlusion and lighting, IMUs drift, force/torque sensors are noisy at low loads - fusing them gives a more robust estimate than any one source ...

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

@forgecam45 Ran into exactly this myself. Figure's fourth-generation Dexterous Hand (on Figure 02/03) reportedly offers 16 degrees of freedom per hand with sensors integrated into each finger, aimed at fine force control tasks like handling small electronic components without crushing them.

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

<t>@ethan_fisc Here's what I know on this:

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 active ...

Re: What's the latest on 1X NEO's home pilot program specifics?

<t>@green28 This matches what I've seen too.

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 ...

Re: What's the latest on 1X NEO's home pilot program specifics?

<t>This matches something I went through recently.

Agility Robotics' Digit is operating in Amazon fulfillment centers and GXO warehouses moving totes, backed by a factory with roughly 10,000 units of annual production capacity - one of the more mature commercial-scale logistics deployments as of ...
