Abstract—Wheelchairs are essential assistive devices for many people with disabilities. This paper describes the design and implementation of an environmentallyfriendly, flexible electric wheelchair that can change sitting postures according to the user’s demand and can change its structure to operate in different terrains. Furthermore, a safety system that observes and informs the wheelchair user about the operating status of the wheelchair such as speed, temperature, and tilt angle, and about the health status of the user such as heart rate, was developed. Additionally, experimental results showed that the proposed wheelchair operated stably at a speed of 5 km/h and a load of 65 kg, and the effectiveness of the safety system was also clearly confirmed.
