Jumper Replica
English | 简体中文
An independent geometry-recovery and physical-fit reference project for KingKong Robotics Jumper, pinned to 61d065219fca767f3142c8f10aff59eae5a5a004. Current stage: digital geometry and reference slicing complete; no physical replica built or validated. Updated 2026-10-08 (Asia/Shanghai).
What is ready
- Original-coordinate millimeter geometry: 41 link references, 1,364 connected mesh components, and 13 solids closed by vertex-only seam welding.
- 46 independently validated faceted STEP files. These retain triangulated faces rather than original parametric CAD.
- Six pilot fit components with oriented STL, configured 3MF, reference PLA settings and measurement checklists.
- Source HOME assembly GLB/STL, joint schedule, mounting/rim observations, and a 6000 × 4800 annotated exploded poster with 66 callouts and an editable Blender scene.
- A pinned upstream source snapshot, provenance/hashes, reusable scripts and offline integrity validation. The project can be moved away from the original checkout.
Counts describe model representations and rendering groups, not a confirmed manufacturing BOM. The 66 annotations include three module references and an unidentified internal group. Even the remaining 62 groups are not a verified quantity of independent manufactured parts. Geometry closure and successful slicing do not prove physical fit or strength.

python3 tools/validate_release.py
The validator uses the Python standard library; no robot, simulator, slicer, GPU, CAD application or network is required. Install the optional geometry dependencies only when regenerating or deeply inspecting meshes:
python3.12 -m venv .venv .venv/bin/python -m pip install -r requirements-geometry.txt
Directory map
upstream_snapshot/: selected unmodified source files, original meter-scale STL and source provenance. geometry/: derived mm geometry and extraction evidence. assembly/: original HOME assembly references, exploded render scene and annotations. printing/: six fit samples, profiles and slicing evidence. experiments/reference_gcode/: guidance for locally generated toolpaths; raw G-code is excluded from publication. catalog/: component-group status, not a procurement BOM. external_references/: vendor links and measurements, without vendor CAD binaries. tools/: independent regeneration/validation scripts. docs/: engineering state and workflows. provenance/: hashes and source/change records.
The snapshot contains 51 selected files, not the full training/controller repository. No original firmware, custom PCB, wire harness, complete fastener list, material/tolerance specification or validated whole-robot assembly is supplied here. This project does not claim the vendor's grasp/jump performance.
