Disabled people are in a dire need of electronic assistance. There are a couple of electronic assisting devices that bring their life to an easier turn. In this paper, we describe the design and implementation of a personal assistant robot for blind people. Visually impaired people need such personal assistant devices for they provide a real-time assistance regarding any necessary problem that blind people face. Some of those main problems are navigation in the indoors, identifying objects around unless getting a physical sense of those objects and sensing the surrounding with the distance of multiple objects. Our paper discusses the various application targeting features like using the LIDAR for local mapping, using a 3D camera for understanding the depth of the surrounding so that the person understands the distance and other information of the objects around. This design has been experimentally validated and required observations are posted in this paper.
