Finger Creeper - Seven-Finger Palm and Adapted Finger Mechanism · 模型 60200
This is my preliminary mechanical design for a seven-finger, tendon-driven crawling hand inspired by the Fingercreeper silhouette in Elden Ring. It uses a symmetric 2-3-2 finger arrangement and a palm designed to accommodate four Hiwonder HTD-35H servos. The finger geometry is adapted from simo 83's Endoarm model: https://grabcad.com/library/endoarm-stl-1 My modifications include scaling the reference finger chain to 165 mm, revising joint bores and clearances, adding separate joint hardware, developing compact root brackets, designing the palm carrier, and arranging and mirroring the seven fingers. The original three-segment finger geometry and mechanism are credited to simo 83. Included files: - Seven-finger mechanical assembly with the palm - Complete single-finger assembly - Separate finger, bracket and hardware STEP files - Normal and mirrored STL files for printable structural parts - Palm in STEP, STL and SolidWorks 2025 formats - CAD previews and a single-finger exploded view All dimensions are in millimeters. STEP assemblies can be imported into SolidWorks, but do not include native assembly mates or a parametric feature history. Metal hardware models are assembly references, not plastic printing files. Servo models and the complete tendon transmission are not included. This is a preliminary CAD study. Printed fit, strength, tendon routing, return mechanisms, balance and crawling performance still require physical testing. Design and revisions: Guolin Xu. CAD scripting, checking and rendering were assisted by OpenAI Codex under my iterative design instructions. Additional crawling-hand inspiration: poormansguidetoanimatronics
