Abstract:

This paper describes that one of the major problem for wheelchair users is crossing the terraced road, such as sidewalks, shopping center, as well as up and down stairs. In addition, the results of questionnaires that distributed to users of wheel chairs, showed that 70% of respondents do not want anymore accompanied by a guide when have their activities inside and outside of home. To overcome this conditions an advance mechanism is needed to climb the stair and sidewalk/curb. The design includes two different main mechanisms used to resolve the problem of stair climbing namely as scissor lifting mechanism and conveyor belt type mechanism. Control system used for this mechanism is very simple in construction and normally open type. From this design, an electric wheelchair prototype that can climb stairs and turn, move back and forth, tilting seat can be adjusted, is produced. The entire movement of this wheelchair is controlled by user.
