3. Design Concept for a Smart Wheelchair
- The display and control systems require an eDP+ touch-screen panel and a computer board running Windows 10 (a minicomputer), respectively.
- Two 10-inch-diameter castor wheels with front-wheel drive.
- Three sets of levers control the six-inch-diameter rear-wheel drive castors.
- The chair can recline to 60 degrees and move in four directions (forward, back, left, and right).
- Three different levels of movement speed adjustment.
- Developing control systems for various devices through the sensor system displayed on the touch screen.
- C Sharp (C#) programming languages were used to write the control unit programs.
- The sensor system measures the car’s distance from the obstacles in front of it; if it is less than one meter, it will cause the wheelchair to stop automatically.
- While the automobile travels, eight sets of lights are visible, along with a liquid crystal display (LCD) panel that displays the battery’s status.
- Battery charging outlets and a charger with a minimum voltage and current of 24 volts and 10 amps, respectively.
- A four-ball, 250-watt, 24-volt direct current (DC) motor with an integrated reduction gear.
- The DC motor driving unit of the metal-oxide-semiconductor field-effect transistor (MOSFET) hybrid type is at least 80 amps in size.

Stage Name | Designing an Innovative Wheelchair Process |
---|---|
Problem identification and motivation | Through a thorough analysis of the approaches and objects to be identified, a search of the many positioning systems enabled us to examine the accuracy of various applications in both internal and external contexts, leading to the problem’s identification. The positioning error of the wheelchair results in a complete loss of information when driven in areas with weak internet or no Global Positioning System (GPS) signal. |
Defining the goals of the solution | According to problem identification and motivation, it is possible to determine which policies to develop and research to minimize errors as much as possible, bearing in mind the external environment and autonomous movement. |
Design and development | This resulted in the system’s architecture and aided in creating diagrams that could detail the many operations the system would carry out. The system’s implementation consisted of three components: a location system, an autonomous wheelchair system, and particular procedures that could optimize the entire program. |
Demonstration | The smart antenna detects the path the smart wheelchair can take, compares it to the initial path chosen by the user, and displays the result on the graphical user interface. This demonstrates how the unique approach reduced the positioning error. |
Evaluation | Three detection nodes are utilized in various positions to test the application quality and then consider whether the internal or external environment affects the accuracy of the system’s performance. |
