Project Summary

Robotics is the branch of technology that deals with the design, construction, operation, and application of robots. A machine capable of carrying out a complex series of actions automatically, esp. one programmable by a computers is defined as a robot. And, Obstacle avoidance refers to the ability of a robot to detect obstacles in its way if there are any and thus make its own obstacle free path.  Many industries are using robots for their work due to their high efficiency, speed, accuracy and reliability.  Whenever we think about robotics the first that comes to our mind is automation. Robots are able to perform tasks automatically without any human interruption, except initial instructions and programs set being provided to them.In robotics, obstacle avoidance is the task of satisfying some control objective subject to non-intersection or non-collision position constraints. In unmanned air vehicles,. What is critical about obstacle avoidance concept in this area is the growing need of usage of unmanned aerial vehicles in urban areas for especially military applications where it can be very useful in city wars. Normally obstacle avoidance is considered to be distinct from path planning in that one is usually implemented as a reactive control law while the other involves the pre-computation of an obstacle-free path which a controller will then guide a robot along.  My project is obstacle avoiding robot The obstacle detection is primary requirement of this autonomous robot. with this application  we can make many other robots like fire fighter robot, home cleaning robot, military robot and many other type of robots. This robot gets the information from surrounding area through mounted sensors on the robot. Some sensing devices used for obstacle detection like bump sensor, infrared sensor, ultrasonic sensor etc. Ultrasonic sensor is most suitable for obstacle detection and it is of low cost and has high ranging capability. The obstacle avoidance robotic vehicle uses ultrasonic sensors for its movements. A microcontroller ARDUINO UNO is used to achieve the desired operation. The motors are connected through motor driver IC to microcontroller. The ultrasonic sensor is attached in front of the robot. Whenever the robot is going on the desired path the ultrasonic sensor transmits the ultrasonic waves continuously from its sensor head. Whenever an obstacle comes ahead of it the ultrasonic waves are reflected back from an object and that information is passed to the microcontroller. The ultrasonic sensor consists of a multi vibrator, fixed to the base. The multi vibrator is combination of a resonator and vibrator.

Project Objectives

 The main objective of my project is making robots more advanced and make robots independent and more efficient. Obstacle avoidance make the robot more advanced and without human interruption they will operate and working. with this feature we can make military robots  advanced they can work without any human interruption in war areas also we can make robots for domestic uses as well as used in medical filed and many other fields.

Project Implementation Method

      The obstacle avoidance robotic vehicle uses ultrasonic sensors for its movements. A microcontroller ARDUINO UNO is used to achieve the desired operation. The motors are connected through motor driver IC to microcontroller. The ultrasonic sensor is attached in front of the robot.

Whenever the robot is going on the desired path the ultrasonic sensor transmits the ultrasonic waves continuously from its sensor head. Whenever an obstacle comes ahead of it the ultrasonic waves are reflected back from an object and that information is passed to the microcontroller. The microcontroller controls the motors left, right, back, front, based on ultrasonic signals. In order to control the speed of each motor pulse width modulation is used.

Benefits of the Project

    Previous robots are working on instructions when one task performed they are waiting for next instructions. But this robot is working automatically once programed then it starts working automatically without in human interruption. With this feature we can make robots independent in some aspects.  With this feature we can make many others robots like domestic or household robots these type of robots are used in home for different kind of works for example robotic pool cleaners, robotics sweepers, robotic vacuum cleaner, robotic sewer cleaners and other robots that can perform different tasks. Scrutiny and tele-presence robots can also be considered as domestic robot. Medical robot Robots are also used in medical field for different jobs like surgical treatment. Also a number of robotic directed automobiles and perhaps lifting supporters. Service robots Robot that cannot be classed into any other types by practice these robots could be various data collecting robot, robots employed for research and robot prepared to exhibit technologies. Military robot  Robots are also playing an important role in military .This type of robots consists of bomb discarding robots. Various shipping robots, exploration drones, and many other fields. Entertainment robots These types of are working for entertainment. This is extremely wide-ranging category. It begins with running photo frames and concludes with real heavy weight movement simulators. Hobby and competition robots These types of robots are created by students like line follower, maze solving robot, fire fight robot, wall follower robot, hand gesture controlled robots, obstacle avoiding robot and Voice controlled robots. Mostly these types of robots are created for competitions.
