An Electric Tricycle for Leg-impaired People

Abstract

The purposes of this research were to: 1) develop an electric tricycle for disables who are leg-impaired, 2) determine the efficiency of the developed electric tricycle for disables, and 3) study the satisfaction of users towards the developed electric tricycle for disables. The sample group included 5 experts to validate the efficiency of the developed electric tricycle for disables and 3 leg-impaired disables derived by purposive sampling technique. The research tools were experimental recording forms and satisfaction questionnaires analyzed by mean and SD. The results revealed that the developed electric tricycle was validated by the experts with high efficiency and could be practically used by the disables. The design of the developed electric tricycle was rated at very good level and the disables could drive at the average speed of 39.33 km/hr. with the distance of approximately 19.66 km. The electric tricycle could be continuously used for 1.18 hrs. with the duration for battery charge of approximately 6.18 hrs. The breaking distance is 2.26 meter within 3.28 sec. When compared with the traditional disable tricycle at the distance of 10 meter, it was found that the developed electric tricycle was 38.74% faster. The users reported very high satisfaction on the strong structure and appropriate materials. Moreover, the size of the developed electric tricycle was suitable making it easy to ride. The transmission system is also appropriate with nice design.
