Abstract
This work presents a technique for accurately measuring the shape of deformable, non-specular convex surfaces, such as elastomeric membranes commonly used in soft robotics. The primary goal is to optically characterize these surfaces using a laser triangulation system. An experimental setup was developed in which a membrane was subjected to varying pressures and voltages, and its deformation profile was captured using a CMOS sensor. A laser line was projected onto the surface, and an algorithm reconstructed its three-dimensional geometry by analyzing multiple profiles acquired at 15-degree rotational intervals. The results demonstrate that the proposed method provides a reliable and effective approach for the optical characterization of soft, non-reflective materials.
