This study has been undertaken which proposes a way to use the Ultrasonic sensor to map the space in 3D. In this project, an Ultrasonic sensor is used to map the area using Multivariate Gaussian Distribution. The Ultrasonic sensors give the reading for the distance of object. This reading is then used to calculate the probability of position of obstacle in the field of vision of that particular sensor. The Multivariate Probability Distribution function has two variables ‘r’ and ‘θ’ (theta) which are varied at particular instants to find the probability at each cell.
