Abstract: REAL TIME SHAPE PROGRAMMING DEVICE FOR SOFT MAGNETIC SOFT MATERIALS AND ROBOTS The invention provides a multifunctional fabrication and programming system (100) for soft magnetic actuators, integrating three core modules to enable programmable particle alignment and localized curing. A rotatable magnetic field generator (102) comprising permanent magnets (114) on a 360° disk allows dynamic orientation of a uniform magnetic field to align soft magnetic particles in uncured polymer. A motorized sample bed (104) offers rotational and translational positioning, facilitating spatially varied magnetic alignment. A UV/laser light module (108) mounted on a guiding rail employs adjustable optics or masks for region-specific curing or thermal activation, selectively locking magnetic patterns into the matrix. Additionally, a laser-based heating module (112) enables site-specific reprogramming of pre-cured actuators by locally softening the polymer, allowing realignment and fixation of magnetic particles under a new field.
