Abstract: This paper develops a low-cost assistive robotic mobility platform for the visually impaired individuals and elderly people, addressing high cost and functional fragmentation. Its hybrid wheeled-legged structure enables flat-ground navigation and stair climbing. The prototype which weighs 1.9 kg and costs about €400 uses low-cost components and meets design specs.
Keywords: Service Robots, Mobile Robots, Hybrid Wheeled-legged Robots, Prototype, Assistance of elderly people.
