Preface

Nowadays, most of us are enjoying our happy life. Unfortunately, we see a large number of disabled around us. If a teacher had something wrong with legs, it would be so difficult for him or her to walk up to the platform. Especially the teacher has to move with a wheelchair, it will be more inconvenient. Just like Mr.Mouw. So, we think it is necessary and important to make a machine to lift a wheelchair. Below, we will introduce our designs.
