What it does
Buddy+ 2.0 is an intelligent e-rollator designed to improve mobility for people with limited movement abilities. Its goal is to address common issues such as poor posture, risk of stumbling, and lack of support in everyday situations.
Your inspiration
The idea emerged from everyday observations. I noticed how many elderly people tend to lean too far forward when using a rollator, a posture that is unhealthy in the long run. At the same time, I recognized the increased risk of stumbling over obstacles and losing control. These impressions motivated me to create a modern solution that not only supports mobility but also helps people regain a sense of independence in their daily lives.
How it works
The e-rollator is designed to assist with long distance walks using an electric drive, which can be switched off when not needed. It is equipped with 360° 3D cameras and laser sensors placed around the frame. These detect the surroundings, analyze potential hazards, and measure distances precisely. The collected data is processed by an integrated artificial intelligence system. If a hazard is detected, the user is warned in time by a flashing light, giving them the chance to react adequately. At the same time, sensors in the handles monitor the user’s posture. If the user leans too far forward, they receive immediate feedback. eBuddy+ 2.0 is also designed with everyday practicality in mind: it can be folded compactly at the push of a button, features adjustable height, and allows the handles to be individually set to the optimal angle. An integrated seat and shopping bag provide additional comfort.
Design process
The starting point was the everyday observation of common problems in the use of rollators. I began to explore the topic of mobility in old age more intensively and actively sought conversations with elderly people. Based on these insights, I created the first concept sketches. The focus was on ergonomic design and an intuitive, easy-to-use interface tailored to the needs of older users. I repeatedly asked myself: How can I develop an elegant, compact rollator that still integrates value-adding functions? After several drafts, I settled on a clear basic form and translated the concept into initial CAD models. This allowed me to test the feasibility of the technical components and refine the design in a targeted way.
How it is different
There are many rollators on the market. However, this concept deliberately breaks with the traditional image of conventional models. It follows a holistic approach that combines technology, design, and user experience. The goal is not just to create a walking aid, but a daily companion that inspires confidence and is both visually appealing and functionally tailored to the users' needs. The aim was to design a product that does not look like a medical device, but is perceived as a modern, high-quality object. This sets it apart from existing solutions, which often appear purely technical or medical and place little emphasis on appearance, self-esteem, or user acceptance.
Future plans
The project is currently a digital concept based on research and user observations. My goal is to further develop the idea, build a first prototype, and test the technical feasibility of the key functions. I also aim to evaluate not only the functionality but the acceptance of the product within the target group.
