This research focuses on the design of a three-finger adaptive gripper using additive manufacturing and electromechanical actuators, with the purpose of providing a low-cost, efficient, and reliable solution for easy integration with any robot arm for industrial and research purposes. During the development phase, 3D printing materials were employed in the gripper's design, with Polylactic Acid (PLA) filament used for the rigid mechanical components and Thermoplastic Polyurethane (TPU) for the flexible membranes that distribute pressure to the resistive force sensors. Stress analysis and simulations were conducted to evaluate the performance of the components under load and to gradually refine the design of the adaptive gripper.

This is a case of a 65-year-old patient with isolated progressive tongue hypertrophy of unclear etiology for 5 years. We navigate the causes of macroglossia and discuss the clinical and diagnostic procedures that helped us narrow the differential diagnoses for our patient.
