Design and Fabrication of Attachable Wheelchair Automator
Design and Fabrication of Attachable Wheelchair Automator report
Abstract: One of the basic problems of user on manual wheelchair is overcoming architectural barriers (kerbs, stairs etc.) on its way. Even though many research studies have been reported in different fields to increase the independence of wheelchair users, the question of overcoming obstacles by a wheelchair always remains as topic of discussion for many researchers. In our project amotor operatedstair climbing wheelchair concept which can overcome the architectural barriers to a considerable extenthas been developed.This project involves the design of an ergonomically designed battery powered wheel chair for multipurpose use.Stair climbing functionality is embedded in the design through its structure and mechanism. All the design parameters of wheelchair were based on the standard design of the stairs in India. Major part of the projectfocuses on the proposed design concept and concludes by discussing upon the physical working model developed for the proposed design solution.Department of Mechanical Engineering, VVCE, MysuruPage 1Design and fabrication of multi-purpose wheelchair for differently-abled person experience significant disabilities. Disabilities of various partssuch as eye, ear, hand, leg etc. Limb disability is one of the disabilities which are caused due to various reasons such as deformation by birth, war, disorders such as diabetes. Lower limb of sports person also suffershuge blows while playing and are always at the risk of suffering severe injuries. These injures sometimes may be a permanent disability.m or single arm drive enables a user to self-propel a manual wheelchair using only a single armas seen in Figure1.5. The large wheel on the same side as the arm to be used is fitted with two concentric handrims, one of smaller diameter than the other. On most models the outer, smaller rim, is connected to the wheel on the opposite side by an inner concentric axle. Whenboth handrims are grasped together, the chair may be propelled forward or backward in a straight line. When eitherhand-rim is moved independently, only a single wheel is used and the chair will turn left or right in response to the hand-rim.
