Abstract - Embedded systems is a widely implemented
space is the ultrasonic sensor. Having simple trigger and echo pins and simple transmission and reception based on the reflection principle, it is not only easy to understand the working but also program it. Thus, the all crucial measurement data obtained by the ultrasonic sensors are sent to the standalone system to process. Thereafter a mapped model is prepared that effectively presents a sort of a blueprint of the whole enclosed space in front of the user.
domain with Robotics as an ever growing filed. In this paper, a method for measuring and obtaining the dimensions of an enclosed space is proposed. For the purpose of measuring, a robot is built which has ultrasonic sensors mounted on it. This robot can be sent in places inaccessible under normal circumstances, and is controlled remotely using a hand mounted module operated by a controller which consists of an accelerometer. The transmission and receiving of data is done using radio frequency based modules. The data obtained from the ultrasonic sensors mounted on the robot is then ultimately mapped on the user workstation. This is done in order to get a clear view of the space without even entering it. Key Words: Arduino, Ultrasonic sensors, Accelerometer, Environment mapping, processing development environment.
1. INTRODUCTION There exist many enclosed spaces around us which might be inhabited by humans or which are totally untouched. However, there are very few techniques to explore and delve into these spaces for the sake of operating in them or for whatever reasons one might want to. In this extract we present a technique to not only explore and uncover these very enclosed spaces but employ a system by making use of the contemporary technologies which measures the distances of the whole space with respect to a pivot point. The contemporary technologies used are cheap and provide an open source solution so as to allow improvements and enhancements as and when needed in the near future. The pivot point is a robot, maneuverable from a distance by a person.

2. RELATED WORK In the proposed system the major control which user has is maneuvering the robot to the required areas. Various navigation methods have been proposed. For example, gyroscopes have been used, but as rightly suggested by [1], when there is a tilt in the gyro, there is a change in output voltage. However, the voltage level resets back to zero if the tilt remains constant which is undesirable. Thus the gyro reports erroneous readings which are unfavorable for the robot movement. Hence to solve this problem accelerometer is preferred as it outputs steady duty cycles. It is also easier for the person to understand the movements.
As far as the technologies are concerned, we focus primarily on embedded system integrated with necessary sensors. We use a widely known and used microcontrollerbased kit Arduino (different variants).The job of maneuvering the robot is accomplished by the usage of an accelerometer based Hand mounted module (HMM). The primary sensor for measuring the distance of the enclosed
