It uses a pair of flexures (aluminum or titanium plates on top and bottom) to set relative stiffnesses of Fx, Fy, Fz, Tx, Ty, Tz. A central rod carries a disk with four small neodymium magnets which moves when loads are applied. Four AS5013 hall array ICs are positioned just below the rest positions of the magnets on a single PCB. M3 standoffs and screws hold the entire stack together. <img src='v1/img/screenshot1.png' width=400px> + +Features of a "good" 6 DOF flexure: +* Ability to tune relative stiffnesses (e.g. Fx/Fz, Tx/Tz, etc.) +* Minimal cross talk (i.e., Fx doesn't induce a displacement in y or a twist, etc.) +* Fits into a reasonably small bounding volume.
