Abstract
Our project is important because Palestine is considered one of the states which has high proportion of disabled people relative to its population. and we need to help them to live normal life as any one does.
One of the biggest obstacles facing a disabled person climbing stairs, there is a kind of chairs that can climb the stairs which were previously invented. Our project is a developed chair from this kind to make the chair integrated in terms of safety and multi-functionality.
Our idea is a system for the disabled people which have many features, first it guarantees climbing the stairs safely by sensing the tilt and balancing the chair based on the angle of the chair inclination, and ensures that the person is still fine and has not fallen from his chair, also make them control their house devices wirelessly.
So, the main objectives of our project providing an integrated support environment for people to live normal life.
We used a model, which is a children's toy available in the market to represent the idea of climbing the stairs (Through an elastic belt that has a strong cohesion with the ground and allows movement in the same time), in the lowest cost. As this:

After that, we had made a mobile application on app inventor, which we used it as a controlling system, to control the movement and the speed, ensure that the person in fine situation, deal with emergency statues, and control the house devices using WIFI.
We used ESP32 module with Arduino IDE because it supports the features which we used.
And we used a sensor which can measure angular momentum or rotation along all the three axes in the chair to handle the seats' tilt to add safety while climbing the stair.
