  1. OBSTACLE AVOIDER USING SENSOR TECHNOLOGY Kirankumar Dileepraju BojjaHaranath

  2. What is a sensor? Wikipedia Definition “ Device that detects(senses) changes in the ambient conditions or in the state of another device or a system, and conveys or records this information in a certain manner”

  3. SPECIFICATIONS OFSENSOR • Accuracy:error between the result of a measurement and the true value being measured. • Resolution: the smallest increment of measure that a device can make. • Sensitivity: the ratio between the change in the output signal to a small change in input physical signal. Slope of the input-output fit line. • Repeatability/Precision: the ability of the sensor to output the same value for the same input over a number of trials

  4. TYPES OFSENSORS • Bump sensors, which are switches activated when the robot touches an obstacle. • Infrared proximity detectors, which detect the presence of an object in front of the sensor. • Ultrasonic range sensors, which determine the range of the object in front of it. • Laser range finders, which work on the same principle as ultrasonic

  5. PRIMARY REQUIREMENTOF ROBOT • Obstacle avoidance is a primary requirement for any autonomous mobile robot. • The robot acquires information about its surroundings through sensors mounted on the robot.

  6. COMPONENTS • Micro controller • AVR Board Atmega 8 • Connecting Wires • Infrared Sensor ( analog ) • LCD Screen • DC Adapter • 2 DC Motors • USB-ASP Programmer • 3 Pin Relimate for IR Sensor • 4 Pin Relimate for LED • 6 Pin Relimate for Programmer • 8 Pin Relimate for LCD
