Re: What's a reasonable service interval for a commercial-grade joint actuator?
Sorry if this is a basic question, but
A lot of the per-joint cost in a modern actuator isn't the motor - it's the combination of a precision gearbox, integrated encoders, torque sensing, and the driver electronics, all of which have to fit inside a housing the size of a fist.

Re: Best practices for IMU-to-camera extrinsic calibration on a moving robot?
<t>@williams84 Counterpoint:
IMU drift over time (bias instability) is usually the real culprit behind slowly diverging state estimates, not noise - it's typically handled with sensor fusion against other references (visual odometry, joint kinematics) rather than trying to eliminate drift at the ...

Re: Anyone tracking sensor cost trends the way we track actuator cost trends?
New to this, so forgive me if this is obvious -
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.

@amandawhite Here's what I know on this:

Compliant wrists that absorb impact during a bad approach or misjudged contact reduce mechanical stress on the whole arm, which matters a lot for long-term reliability even though it's a less visible feature than the hand itself. Tendon-driven fingers let ...

<t>@noah_pate This matches what I've seen too.
Estimated total operational commercial humanoids worldwide sit around 7,000-8,000 units as of mid-2026, broken down roughly as Optimus Gen 3 (1,000+), Unitree (5,500+ cumulative), Agility Digit (~250), Apptronik Apollo (~80), and Figure (~150 ...

<t>@nicole10 From what I've seen:
Starting in simulation (even a simplified physics sim of just the leg or the target gait) before touching real hardware is one of the more reliable ways to avoid destroying expensive parts while debugging balance and walking control from scratch.

<t>@servobre20 I'd take that specific number with a grain of salt, honestly.
