01 / Under the shell

The specifications.

Hardware, build and software on one sheet. Every fact links to where we found it.

T.A.R.A. is an industrial robotic arm with STL files for all robot parts. The repository describes printing the parts in PLA or ABS and assembling servo-driven hand, wrist, elbow, shoulder and base joints, with Arduino control code.

Building it

Print settings
Parts use 20% infill except the base, which uses 50%; the README says parts can be printed without supports or adhesions. README
Assembly
The README describes hand, wrist, elbow, shoulder and base servo positions. README

Software & simulation

Control
Arduino code to control the robot. README
Simulation
Jupyter notebooks with Python code to run robot simulations. README

02 / The files behind the robot

What’s open.

Six parts of the build, each checked separately. Gaps stay visible.

03 / Know before you build

Can you sell it?

Check firstCheck before commercial use

No license was found for the design files, so no reuse rights are granted. Ask the maker before building anything to sell.
