Abstract - The home robotics is an evolution of the existing
difference. Disparity map is measurement of difference between two images.
home automation. This project presents an approach to home robot using Raspberry Pi .This project is specially designed for patients suffering from serious diseases like paralysis which will helpful to family of that patient, the robot only work through the authorized persons instructions . This design is a small portable monitoring system for home & office. This includes the different process like voice reorganization, face detection, object localization, pick and place. All this is controlled by Raspberry Pi processor. The pairs of webcams are used & are able to implement a basic frontal obstacle avoidance system. With the help of the stereoscopic system, we inferred the position of the object that serve as reference to the bot. The final system is capable of identifying & following target object in a distance of over 10 Ft. The model B Raspberry Pi is a 3.5 W, computer with 1.2 GHz ARM V8 processor & multiple i/o interfaces. We use OpenCV libraries to process images & POCKETSPHINX for speech recognition.

Operation on environment
Robotics plays very vital role in various fields of our society such as personal security, business, industries, etc. Starting from small houses to huge scale industries, now home robot is essential and plays very vital role to fulfill our day to day aspects in many ways. Now a day keeping care taker for elder people or servant due to different reasons due to these reasons domestic robots are useful. Domestic robots are of two types 1. Indoor Domestic Robots; 2. Outdoor Domestic Robots. The home robots are come under Indoor domestic robots. This machine is mobile machine, which could pick up the object from one place and deliver at particular place, without complaining & getting tired. The number of human interactions for the control of basic human function can be replaced by using home robot which can be considered as an act of using electronic system\devices and its programming. What actions the system is to execute can be controlled by using processing component of the system which is the heart of the system. In this proposed system, the Raspberry pi as a really powerful microcontroller and in the mean time it will act as a normal use computer. Hence this system will work in standalone mode without the necessity of the PC. Pair of webcams is used and are able to implement a basic frontal obstacle avoidance system. The two images captured between two cameras called disparity. Disparity means

Compter vision is one of the most demanding areas in a robotic field. To move materials, parts, tools or specialiezed device through variable programmed motion for performance of variety of tasks robot act as a programmed motion for performance of variety of tasks. Robot act as a programmable multifunction manipulator.. This proposed system is entirely voice controlled system and for this POCKETSPHINX software is used. Pocketsphinx is a part of the CMU Sphinx Open Source Toolkit For Speech Recognition.

I. 1.1 LITERATURE SURVEY :
|
In the 18th century scientists made one doll type machine which was stationary and used to help to pick up the object from one and deliver at particular place. As this machine was stationary it could not deliver the objects from far distances so there was need for mobile machine, which could pick up the object from one place and deliver at particular place. The robot in the project will overcomes all the problems. There are lots of home robots available in the market which are designed and manufactured by different companies, they are very costly. This is one of the robot which is manufactured at low manufacturing cost. ASIAN JOURNAL OF SCIENTIFIC RESEARCH, 2015 this paper published the Hand Gesture based control of robotic hand using Raspberry Pi processor.
