The first commercial electric wheelchairs were only heavy-duty manual folding wheelchairs powered by lead-acid batteries, motors, transmission belts, and pulleys. Those systems known as traditional electric wheelchairs are very simple. They need to use a joystick to control the movement of the wheelchair, and there is no programmability. Seating systems usually consist of a harness seat and backrest trim, which significantly limits personal posture support.

 

Electric wheelchairs are just one of many sports options available for people with disabilities. We mentioned that electric wheelchairs are the most popular, so everyone likes to play automatic wheelchairs. More importantly, using an automatic wheelchair, the entire upper body is exercised. In this way, the muscles of the upper body will become stronger and stronger. This may be because they have experienced something they consider impossible.

 

The emergence of the power base is located under the seat, contains a motor and a battery, and can achieve significant mechanical technological advances in electric wheelchairs. The power base divides the electric wheelchair into two parts: a base that provides mobility and a seat system that provides posture support. While shifting from traditional electric wheelchairs to powered base wheelchairs, significant progress has been made in electronic systems. Some of these mechanical and electrical advancements include the ability to increase power tilt and recline systems and programmable performance settings (e.g., forward speed, cornering speed, and acceleration). The joystick is the most basic and commonly used device for controlling electric wheelchairs, and it is similar to the joystick used in computer games. Advances in control systems allow individuals to control wheelchairs through any voluntary movement. For example, some electric wheelchairs can be controlled by using head movement, breathing actuation, tongue movement or lower limb control.
