As an intelligent auxiliary mobility device for home and outdoor use, electric wheelchairs have compact body size and flexible steering performance, which is very suitable for complex indoor home environments. For the elderly with inconvenient legs and feet and disabled people with limited mobility, indoor activities such as moving between rooms, fetching items and adjusting sitting postures are difficult challenges in daily life. In the past, they could only stay in a fixed position for a long time and needed family members to help complete various trivial household activities. The emergence of electric wheelchairs completely changes this situation. Users can flexibly and freely move between bedroom, living room, kitchen, bathroom and balcony by operating the electric wheelchair. They can independently complete daily tasks such as fetching drinking water, taking daily necessities, tidying up personal items and basking in the sun on the balcony. The intelligent and labor-saving characteristics of electric wheelchairs enable users to take care of their basic household life independently, reduce dependence on family care, and make daily home life more convenient, free and comfortable.
