detailed specs to build a humanoid robot (with kids)

Components (139)

Reference	Value	Description
Q0	Two-pole main disconnect	Disconnect rating, poles, fault rating, and jurisdiction are unresolved. PE bypasses Q0.
QF1	PS1 AC branch protection	Rating and curve require prospective fault current plus the unpublished LRS-350 inrush maximum, duration, waveform, T50, and I-squared-t. Typical inrush alone is insufficient.
QF2	PS2 AC branch protection	Rating and curve require prospective fault current and inrush coordination.
QF3	PS3 AC branch protection	Regional compute-supply branch protection and inlet arrangement are unresolved.
QWD1	HR-V0 3.3 V-to-24 V watchdog coil driver	Transistor or optocoupler circuit, logic polarity, flyback coordination, creepage, and failure response are unresolved.

UV1	ROBOTIS U2D2 - V0 TTL interface	ROBOTIS names pin 2 VDD but does not publish or permit a sense-only path. Pin 2 is omitted pending written manufacturer evidence or a released and tested custom harness.

AFE1	Load-cell excitation, reference, protection, and anti-alias front ends	Excitation voltage, reference, amplifiers if required, filters, protection, calibration injection, and complete PCB circuit are unresolved.

BAT1	Protected battery pack and conversion - SELECTION REQUIRED	Qualified supplier, chemistry, series count, conversion topology, full-charge and loaded end-of-discharge limits, protected ports, fault current, capacity, enclosure, regeneration, and telemetry are unresolved.

BCU1	Independent battery sequencing and interlock controller	Controller, independent power, voltage threshold circuit, coil drivers, diagnostics, sequencing logic, and safety-inhibit interface are unresolved.

FSR1	PNOZ output-contact protection	Pilz manual p.11 requires output-contact protection. Published maxima are not selections; coordinate the exact protection with coil inrush, conductor, PS2 behavior, and fault current.

FSRH1	HR-30 PNOZ output-contact protection	Pilz manual p.11 requires output-contact protection. Published maxima are not selections; coordinate the exact protection with coil inrush, conductor, PS2 behavior, and fault current.

JHL1	Left-leg harness bulkhead	Connector family, pin numbers, current per contact, keying, shielding, strain relief, and ingress rating are unresolved. Prohibit unreviewed full-conductor DYNAMIXEL links; release a VDD-isolating data harness and require continuity/no-backfeed tests.

JHR1	Right-leg harness bulkhead	Connector family, pin numbers, current per contact, keying, shielding, strain relief, and ingress rating are unresolved. Prohibit unreviewed full-conductor DYNAMIXEL links; release a VDD-isolating data harness and require continuity/no-backfeed tests.

JUA1	Upper-body bus A harness	Connector family, pin map, current capacity, contact count, keying, and strain relief are unresolved. Prohibit standard full-conductor TTL daisy cables; release a data-only harness and require continuity/no-backfeed tests.

JUB1	Upper-body bus B harness	Connector family, pin map, current capacity, contact count, keying, and strain relief are unresolved. Prohibit standard full-conductor TTL daisy cables; release a data-only harness and require continuity/no-backfeed tests.

KWD1,KWH1	Phoenix Contact PLC-RSC-24DC/21	Supplemental normally-open watchdog permit; not safety-rated.,Supplemental watchdog permit only; not a safety relay. Normally-open 11-14 path is required for fail-safe permit behavior.

ML1	ROBOTIS XH540-W270-R left hip yaw, provisional ID 11	Power is star-injected by an individual fuse; only the differential data pair is intended to be bus-connected. Standard 4-pin cables are prohibited because they also carry VDD.

ML2	ROBOTIS XH540-W270-R left hip roll, provisional ID 12	Power is star-injected by an individual fuse; only the differential data pair is intended to be bus-connected. Standard 4-pin cables are prohibited because they also carry VDD.

ML3	ROBOTIS XH540-W270-R left hip pitch, provisional ID 13	Power is star-injected by an individual fuse; only the differential data pair is intended to be bus-connected. Standard 4-pin cables are prohibited because they also carry VDD.

ML4	ROBOTIS XH540-W270-R left knee pitch, provisional ID 14	Power is star-injected by an individual fuse; only the differential data pair is intended to be bus-connected. Standard 4-pin cables are prohibited because they also carry VDD.

ML5	ROBOTIS XH540-W270-R left ankle pitch, provisional ID 15	Power is star-injected by an individual fuse; only the differential data pair is intended to be bus-connected. Standard 4-pin cables are prohibited because they also carry VDD.

ML6	ROBOTIS XH540-W270-R left ankle roll, provisional ID 16	Power is star-injected by an individual fuse; only the differential data pair is intended to be bus-connected. Standard 4-pin cables are prohibited because they also carry VDD.

MR1	ROBOTIS XH540-W270-R right hip yaw, provisional ID 21	Power is star-injected by an individual fuse; only the differential data pair is intended to be bus-connected. Standard 4-pin cables are prohibited because they also carry VDD.

MR2	ROBOTIS XH540-W270-R right hip roll, provisional ID 22	Power is star-injected by an individual fuse; only the differential data pair is intended to be bus-connected. Standard 4-pin cables are prohibited because they also carry VDD.

MR3	ROBOTIS XH540-W270-R right hip pitch, provisional ID 23	Power is star-injected by an individual fuse; only the differential data pair is intended to be bus-connected. Standard 4-pin cables are prohibited because they also carry VDD.

MR4	ROBOTIS XH540-W270-R right knee pitch, provisional ID 24	Power is star-injected by an individual fuse; only the differential data pair is intended to be bus-connected. Standard 4-pin cables are prohibited because they also carry VDD.

MR5	ROBOTIS XH540-W270-R right ankle pitch, provisional ID 25	Power is star-injected by an individual fuse; only the differential data pair is intended to be bus-connected. Standard 4-pin cables are prohibited because they also carry VDD.

MR6	ROBOTIS XH540-W270-R right ankle roll, provisional ID 26	Power is star-injected by an individual fuse; only the differential data pair is intended to be bus-connected. Standard 4-pin cables are prohibited because they also carry VDD.

PS1	Mean Well LRS-350-12	12 V / 29 A candidate. Overload threshold is 110-140% rated power with hiccup recovery; 150% peak is allowed no more than 1 s. Cold-start inrush is 60 A typical at 115/230 VAC, with no published maximum or duration. No protection or conductor value is released.

S0	Dual-NC positively-opening E-stop	IDEC XW dual-NC is a family candidate only. Freeze the exact complete order code, operator/reset/contact/cover/environment details, attach the exact bottom-view drawing, and continuity-test the received unit before replacing TBD terminals.

SH0	HR-30 dual-NC positively-opening E-stop	IDEC XW dual-NC is a family candidate only. Freeze the exact complete order code, operator/reset/contact/cover/environment details, attach the exact bottom-view drawing, and continuity-test the received unit before replacing TBD terminals.
