Autonomous Maze Solver Robot
ROBOT FUNCTIONALITY
Robot functionality based on major systems
• Sensing System
• Motion System
Sensing system based on three ultrasonic sensors that
gives readings to microcontroller about distance
between our robot and maze of wall.
Motion system is based on two continuous servo motors
that are controlled by L298N Dual H-Bridge.
After receiving values of distance from ultrasonic
sensors microcontroller give instructions to motor
driver towards which direction it will have to move
motors.
COMPONENTS DETAILS
 Arduino UNO
 Two Continuous Servo Motors
(Modification in project from DC to Servo Motors)
 One Dual H-Bridge (L298D)
 Three HCSR04 Ultra Sonic Sensors
 Tires
 A Few Male to Male wires
 A Few Male to Female Wires
 9V Rechargeable Battery
 Battery Clipping Wire
INTRODUCTION
Autonomous 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.
BACKGROUND
The 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.
CONCLUSION
In 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.
