About this model

N-DOF: The Modular Robotic Arm This project uses connectors that are compatible with Modular Mounting System (MMS) and GoPro to join motorized robotic modules. !N-DOF ANIMATION Features: - Modular: Ideal for flexible use and re-use. Try different arm designs without having to re-print parts. Disassemble and reassemble with ease. - Limitless: Print the same part multiple times and chain them together. N-DOF = "N Degrees Of Freedom". - Extensible: Have a motor or actuator you want to use in your own robot? Design a joint with GoPro mounts separated by 30 mm... Now it is N-DOF compatible! - Compatible: There are a huge number of mounts for various objects that are already compatible with N-DOF. Search for "Modular Mounting System" or "GoPro". !N-DOF MOUNT Included Modules: - The included modu…
