3D Printing and Build
RIG-Puppy's shell is suitable for FDM 3D printing. This folder includes RIGpuppy0417.STEPas a full mechanical reference model. A public release should also include STL, 3MF, print orientations, and assembly images.
Build Workflow
- Prepare the electronics kit or purchase parts from the BOM.
- Print the mechanical parts.
- Before closing the shell, connect and test the mainboard, display, camera, servos, battery, speaker, and light.
- Flash or update the Puppy firmware.
- Check servo IDs and orientation.
- Assemble the mechanical parts.
- Provision with the "小路同学" mini app.
- Enter and exit calibration.
- Test low-amplitude actions first.
