R29 将嘴部软件行程收至 0–10° 并修正下头壳；指定腿罩/电机配对在四条新质量慢速轨迹中的最低保守名义间隙下界为 11.407 mm。31 根线的防磨件和四工况动力学已补充，但嘴部闭合扭矩仍超过现行 0.05 Nm 结构限制，连续线束及制造公差尚无实物证明，不能放行行走。
沿用R25：31根头部导线改为底部接入，保留前盖与原外形比例；收拢活动线束并取消原侧面专用线孔。底部走线特写。仍为工程候选，离散转头检查不代表连续运动或实物验收。
历史四步回放：R27：R26整机运动回放。 使用已保存的195.44秒实际积分轨迹，逐帧驱动完整R26装配并复核覆盖件的刚体干涉增量；R26质量下的动力学和实物行走仍待验收。

Microduck CM4 Carrier R13: common questions
What microcontroller does the Microduck CM4 Carrier R13 use?
The Microduck CM4 Carrier R13 is built around the DF40C-100DS-0.4V(51), from the Raspberry Pi family.
How big is the Microduck CM4 Carrier R13 PCB?
The Microduck CM4 Carrier R13 measures 58 × 45 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Microduck CM4 Carrier R13?
42 components, from 31 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Microduck CM4 Carrier R13 design files?
From the ldcyes/OpenDuck repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Microduck CM4 Carrier R13 design in my own project?
The repository has no license, so all rights stay with ldcyes. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Microduck CM4 Carrier R13 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
