Author here. This is just a bit of technical discussion on the first bring-up and testing of a new design of force/torque sensor that utilises a Stewart platform geometry. The ultimate goal is that it'll become a fully functional SpaceMouse style device, which at the moment are really only available from one manufacturer due to many mergers and acquisitions and some heavy patent enforcement.
I've released the design open-source, so if anyone is interested in contributing, check out the GitHub repository. Let me know if there are any questions or feedback.
