| Abstract: |
Conventional wheelchairs are widely used by mobility impaired people in Bangladesh. Human labor required by these manual wheelchairs can result in muscle and joint pain and degradation, torn rotor cuffs, repetitive stress injury and carpal tunnel syndrome; which causes secondary injury or further disability. External supports like people’s help or electrical energy to move the wheelchair can minimize these problems. A supporting hand is not available every time. Therefore, both children and adults benefit substantially from access to a means of independent mobility. An electric wheelchair can reduce such problems as the user will be independent and faster. However, it is expensive and not affordable by most of the people of our country. Therefore, it is a challenge to develop a smart electric wheelchair using local technology to minimize cost, with good control and performance. In this paper, design and construction of a two-wheel independent drive smart electric wheelchair for the mobility impaired people is described. Mechanical 3D modelling was completed by using Google Sketch Up software. Arduino Uno and PIC microcontroller were used for electrical drives and controls. Electrical simulation was carried out by using PROTEUS Design Suit. After completing full project, the performance of this smart electric wheelchair is also discussed. |
