Figure Lengend Snippet: Robotically probing soft magnet to classify location and amplitude of external loads. ( ai ) The stretchable soft magnet. ( aii ) The Hall effect sensor array PCB with dimensional units of mm. ( aiii ) Each individual Hall effect sensor taxel position was numbered and physical dimensions were labeled with units of mm. ( b ) The UR5 applied loads to the soft magnet that was placed atop the 3 × 3 Hall effect sensor array within the 3D-printed housing. These nine Hall effect sensor signals were recorded in Simulink and classified with four machine learning algorithms in MATLAB.
