This is a complete set of STLs and OpenSCAD source files to build an animatronic tail.
The scripts and source files are licensed for non-commercial use, please keep this in mind if you plan to make one for yourself.
This tail consists of several plastic discs placed along a steel cable that acts as a flexible element and is actuated using cables connected to a servo. It is designed to be modular, adjustable and highly customizable. Most of the parameters in the OpenSCAD scripts affecting the appearance or motion of the tail can be tweaked and the design of the tail itself allows for parts to be easily moved, adjusted or swapped.
In addition to the 3D printed parts, you will need:
- A TGY-1501 (Or similar) Servo
- Some Nylon coated braided wire fishing leader
- A steel cable to use as your spine (I used 1/4" vinyl coated cable, but you may need to make adjustments to your tail depending on what you use)
- A length of elastic cord (I used 4mm cord, but this is a tweakable parameter)
- Some 3mm thermoset inserts
- Adhesive for gluing plastic parts together
- M3 screws, nuts, washers and square nuts. I mostly used M3x15 and M3x10 screws, but this will depend on the parameters you set in the scripts
- Some means of controlling the servo. I used a custom made board, but there are many ways of accomplishing this.
