    Sensor Technology: Understanding how sensors detect obstacles and how this data is processed
                       for navigation.

                      Critical Thinking and Problem Solving: Students will enhance their troubleshooting skills as
                       they refine their robot’s design to improve obstacle avoidance.

                     Observation

                     In  the “Obstacle  Avoider”  mechatron  activity,  students  will  observe  how  their  robotic  vehicle
                     navigates its environment by detecting and avoiding obstacles. When powered on, the robot will use
                     sensors (like ultrasonic or infrared) to measure distances. As it
                     approaches an obstacle, it will automatically change direction to
                     avoid it, demonstrating real-time decision-making.

                     Application

                     Autonomous Cars: Obstacle avoider technology is essential in
                     self-driving cars to navigate and avoid collisions on the road.

                        4.   Which type of sensor is commonly used in obstacle avoider robots to detect objects in their path?

                             (i)   Temperature sensor                         (ii)   Ultrasonic sensor

                            (iii)   Light sensor                             (iv)   None of these

                                                                          Mechanical Concepts with Mechatron Kit  69
