Intelligent Robotic Walker Design

چکیده
This paper aims to present the current development of an intelligent robotic walker. This machine is designed as a walking aid for the visually impaired. The machine is equipped with different sensors to navigate its motion in the indoor environment such as hospitals, hotels, airports, and museums. The user drives the walker while the two front wheels have the ability to steer in order to avoid obstacles and to seek the target. The control system interacts continuously with the user via voice commands. A self-autonomy goal seeker is developed using fuzzy logic. A discrete logic navigator is used to avoid obstacles in the work space. The indoor environment is described using a 2D road map. The hardware architecture is designed using a hierarchical approach. It is currently under development using microcontrollers. In the paper, the system design and preliminary simulation results are presented.

Design and control of JAIST active robotic walker
This paper presents the design and control of a novel assistive robotic walker that we call “JAIST active robotic walker (JARoW)”. JARoW is developed to provide potential users with sufficient ambulatory capability in an efficient, cost-effective way. Specifically, our focus is placed on how to allow easier maneuverability by creating a natural interface between the user and JARoW. For the purp...
متن کاملDesign of an Active Walking-aid for Elderly People
This paper describes the preliminary design of a light, high stability, robotic system for elderly assistance. The mechanisms used for such assisting devices must exhibit complex mechanical functions that may change during the use. The design has also to be adapted to the morphology and/or pathology. Taking these constraints into account, the design of a robotic walker is presented which provid...
