Plan five shared readout kits plus one spare and reuse suitable host computers. The README names QT Py but does not specify the exact variant; verify board support, logic voltage, pinout and USB serial compatibility before PO.
Start with a single sensor on the bench, verify unloaded magnetic baselines, then collect controlled contact and force data before trying slip detection or robot policies. Changes to geometry, magnets or printing require validation rather than assuming pretrained results transfer.
The paper reports 0.5 mm contact-localization RMSE, 0.27 N normal-force RMSE, 0.12 N shear-force RMSE, 95% held-out slip accuracy and 91% average task success, with a reported 40% improvement over vision-only policies. These are author-reported experimental results, not Armature measurements or safety ratings.
