Free to use. Free to modify. Free to distribute.
The Open-Source Leg hardware is licensed under the CERN-OHL-P v2.0 license. This is a permissive free/open source hardware license developed by CERN specifically for hardware projects and provides the flexibility to commercialize and modify hardware without the obligation to distribute design changes. Here are some of the key points of this license:
If you distribute modified versions of the hardware design, you must keep all existing acknowledgment notes and license disclaimers intact.
If you distribute modified versions of the hardware design, it must be clearly identified with details about the nature of the changes, who made those changes, and when.
You are free to use the hardware design, files, and schematics for learning, research, and commercial purposes.
You are free to reproduce, modify, manufacture, and best use our hardware designs.
You are free to distribute your design commercially and you are not required to make your modifications available to the community.
You cannot claim that the original creator of the design is responsible for any claims caused by your modification of the hardware design.
You cannot use the original creators' names, trademarks, or brands to endorse or promote your modified hardware design without their explicit permission.
While this license allows more flexibility for commercial applications, which we believe is crucial for the adoption of these technologies, we also think that it is important to uphold the spirit of open-source collaboration wherever possible. We highly encourage you to share any improvements or modifications made, further contributing to the overall Open-Source Leg community!
The Open-Source Leg software is licensed under the GNU Lesser General Public License (LGPL v3.0). This is an user-focused weak copyleft license maintained by the Free Software Foundation that protects the freedom of our users and contributors, ensuring our software is free for all its users even when modified and distributed, while still allowing for commercial applications and proprietary software to be built using our software. Here are some of the key points of this license:
LGPL v3.0 grants you the freedom to build your own commercial software or proprietary application using our software but if you plan to distribute a modified version of our software itself then you must also license your modified version under LGPL.
If you distribute modified versions of our software, you need to indicate that you have modified it, and mention when those changes were made.
You are free to use the software for any purpose.
You are free to study how the software works and change it to make it do what you wish.
You are free to build and distribute your own commercial software or proprietary application using our software as long as there is a clear separation between the Open-Source Leg software and your application.
You are free to distribute your modified versions of the Open-Source Leg software itself to others as long as you give the whole Open-Source Leg community a chance to benefit from your changes by making them available to the public under the same license.
You cannot take the software and re-release it under a different license. You must keep the LGPL license intact.
The software is released without warranty, and you cannot hold the authors or contributors liable for any damages that arise from the use of the software.
We believe that this license is the best way to ensure that our software remains free for all its users and all contributions to the software are protected while still allowing for commercial software or proprietary applications to be built using our software.
