Human Following Robot

Abstract

The main purpose of this project is to develop a robot that can follow a human to help their activities easy in a well-planned manner. The first implementation of this project is to detect a human and follows the human in a single human environment. The last implementation is to upgrade this into a robot that can detect humans in a busy environment. When designing a robot to work as a human follower it must fulfill some requirements. The issues which are more focused to resolve in here are, the size and mobility while tracking the humans and obstacle detection of the robot. There are many human assistant robots that manufacture small scale in size, but they are not capable of well-assistance and also most of the physically large robots find it hard to assist and handle some activities. Most of the humans following robots are designed for single work, therefore people tend to spend more money on buying robots to fulfill various work. Usually, the components that are used to develop human detection robots are expensive and it is one of the reasons why these types of assistants are expensive. Here, one of the problems which is mobility of the robot while tracking was resolved by developing a more suitable structure, improving the motor-control method, and adding a step-climbing mechanism to the robot. As the robot is manufactured to follow a human, a method to identify a human using image processing is implemented. Also, a method of detecting the position of human is also implemented. And also, the power plan design and all the electronic developments including the power supply unit development and also the power level checker as well has been implemented. Finally in order to make it less complex the circuit has made on PCB.
