From the project
Evidence-first runtime for a wheeled mobile household robot with bounded actions, replayable events, and fail-closed verification.
Eight-layer controller/power-distribution board for a 48 V desk robot. The package defines the electrical architecture, interfaces, protection, isolated CAN, stackup, placement/thermal constraints, DFM limits, and manufacturing outputs.
The report is written to generated/electricalreport.json. Open kicad/controller.kicadpro with KiCad 10. The detailed EVT companion board has 110 controlled electrical components, four M3 NPTH mounting holes (114 total footprints), eight SMT test pads, 1,250 track/via items, 31 filled copper zones, eight copper layers, and a physical 8 mm primary/secondary…

Workbench-1 Controller: common questions
What microcontroller does the Workbench-1 Controller use?
The Workbench-1 Controller is built around the WCH CH32V307VCT6, from the RISC-V family.
How big is the Workbench-1 Controller PCB?
The Workbench-1 Controller measures 160 × 130 mm, has 8 copper layers and is 1.6 mm thick.
How many components are on the Workbench-1 Controller?
106 components, from 62 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 Workbench-1 Controller design files?
From the Quchaosheng/workbench-mobile-home-robot 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 Workbench-1 Controller design in my own project?
Yes, under the terms of its Apache-2.0 license, which Quchaosheng chose for the repository.
Can I test firmware for the Workbench-1 Controller without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
