This article presents the development of a robotic walker designed from an ergonomic perspective, focused on the specific needs of users. The design integrates a height-adjustable modular system, a rectangular frame with four wheels to ensure stability and manoeuvrability, and a vertical folding mechanism for easy transport. Key components were optimized, such as ergonomic handles with support and grooves for improved grip, an anatomical seat made of memory materials, a durable fabric backrest, and a sports bag-type basket attached by hooks. The 24 mm front wheels are spring-loaded to reduce vibrations, while the 20 mm motorized rear wheels have a non-slip surface for overcoming obstacles. The design incorporates safety features such as reflective strips, integrated lights, and advanced sensors (pressure, TOF, IMU), enhancing user comfort, functionality and safety. This comprehensive approach represents a significant advance in the ergonomics and functionality of robotic walkers.
