No such thing as the SR2. There are the OSR2, SR6, and the SSR1. They are a series of open-source robots designed by TempestMax.
There’s no fixed manufacturer, anyone can build these at home. Assembly instructions can be obtained from Tempest’s Discord server (join from Patreon). They are quite easy to understand and doesn’t require you to be an engineer.
If you don’t have the time for the DIY you can purchase a pre-assembled unit from other builders:
