INTRODUCTIONAutonomous robots means the robots that performs their functions automatically using their programmed algorithm without any human interference. Maze solver robot is also ones of the autonomous robot. There are different algorithm to solve maze. For example wall following, obstacles avoiding, flood fill algorithms etc. The robot that we are going to solve maze, it will use obstacles avoiding algorithm to solve maze.

BACKGROUNDThe problem of solving a maze is approximately 45 years old. But, it is still considered as an important field of robotics. One of most important basic area of robot on which this is based is “Decision Making Algorithm". It is simply defined as a robot which will be placed in an unknown environment, and it requires having a good decision making capability to find the way out using its programmed algorithm.

OBJECTIVES Understand and implement the

obstacles avoiding algorithm. Design a hardware for robot using

microcontroller, ultrasonic sensors and other components as described in below components required portion.

Programme a robot to solve the maze using obstacles avoiding algorithm.

Build a small maze to test our robot.

LIMITATIONS Algorithm has not been achieved 100%. Sometime collides with wall during

turning. Sometimes frictionless surface cause

tires to slip that affect movement.

CONCLUSIONIn conclusion, no doubt, autonomous robotic field is the interesting field of robotics. And it is developing day by day. We have also tried to understand this field by making an autonomous robot that will solve maze using obstacles avoiding algorithm. We learned a lots of things from this project that will not only help us in our academic career but also in our professional life when we design another project.
