Rollator

A walking frame equipped with wheels, handbrakes, and typically a built-in seat, designed to provide stability and support for people with mobility difficulties. Unlike standard walkers that must be lifted with each step, rollators roll forward continuously, reducing the physical effort required and enabling a more natural gait. They are widely used by elderly individuals and people with conditions affecting balance, strength, or endurance. In assistive technology research, rollators have been augmented with sensors, navigation systems, and computing hardware to support wayfinding and obstacle avoidance for users with cognitive or visual impairments.
