Choosing an open-source desktop robotic arm is about more than price and basic specs. The ideal robotic arm platform should deliver high repeatability, sufficient payload capacity, and a practical working reach, all within a reasonable budget. It should also be easy to assemble, program, and deploy. Equally important are a mature software ecosystem, comprehensive documentation, active community support, true open-source accessibility, and the scalability needed for future development.<\/div>
\u00a0<\/div>
In this guide, we\u2019ll highlight three open-source robotic arms: the SO-ARM101 Pro Assembled Kit, reBot <\/strong>Arm<\/strong> B601-DM, and reBot Arm B601-RS<\/strong> for Physical AI and robot learning researchers, universities and research labs, robotics startups, automation developers, and makers.<\/div>
\u00a0<\/div>
From entry-level kits costing a few hundred dollars to professional platforms priced under $2,000, they provide accessible hardware for robotics education, Physical AI research, imitation learning, VLA research, teleoperation, lightweight manipulation tasks, and end-to-end robotics development.<\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

An open-source robotic arm is a programmable robotics platform with open access to its hardware designs, documentation, and source code, enabling users to study, modify, manufacture, and build on the platform under open-source licenses.<\/div>
\u00a0<\/div>
API access and source code availability should not be confused with full-stack openness. Some robotic arms expose SDKs, ROS packages, and simulation models while withholding core hardware assets, including CAD files, schematics, BOMs, and firmware. Others restrict commercial use through their licensing terms. So when choosing a robotic arm, pay attention to whether it offers open software, partially open hardware, or fully open-source.<\/strong><\/div>

The reBot RS and reBot DM featured in this guide are fully open-source robotic arm. Licensed under CERN-OHL-W 2.0<\/span><\/a><\/strong><\/u> and certified by OSHWA. It’s not just open-sourcing the code, but everything, with nothing held back.<\/div>
