Children undergoing radiotherapy often experience fear and anxiety and may require sedation. This project presents the development of an interactive electrical simulator designed to prepare pediatric patients for treatment, in collaboration with the Oncology Department at Hadassah, Ein Kerem. Current wooden models, while helpful, lack movement simulation, patient-specific interaction, and technological engagement.
The proposed simulator is 3D-printed and integrates electrical motion mechanisms, sensors, and control components to realistically simulate the treatment. Engineering calculations and load analyses were conducted to ensure structural and functional reliability. Our simulator is designed for reusability, low maintenance, and cost efficiency, and serves as an effective, scalable preparation tool for hospitalized children.

Corrugations on unpaved roads, commonly known as ‘washboarding’, pose significant safety and comfort issues worldwide. This phenomenon occurs when repeated vehicle movement over loose surfaces deforms the ground, creating a wavy pattern. These patterns cause unexpected vehicle motion and strong vibrations while driving. Traditionally, the only solution has been soil treatment to re-flatten the surface. The goal of this project is to reduce the washboarding effect by developing a mathematical algorithm to predict the contact forces between the wheels and the terrain. To validate our algorithm’s accuracy, we are designing and building a mechanical system that simulates repeated wheel movement. By comparing simulation results to the algorithm’s predictions, we assess the model’s reliability and its potential contribution to vehicle safety and active suspension systems.
