The design helps elderly people living alone when buying food and cooking at home. The adjustable crutch with a multifunctional storage box and the E-walker may be used in 2 modes: • Street mode: E-walker is installed with a 3-roller design which enables the elders to carry objects up and down the stairs. Also, the elders may take rests on E-walker. Installed with a brake and a lift button, the elders may adjust the height when necessary. • Home mode: there is a seat on E-walker, which may be used when cooking in order to reduce physical exertion from standing. The storage box may also be lifted to reduce the involvement of the lower back.
