| − | The UCTRONICS WIFI Smart Robot Car Kit is a flexible vehicular kit particularly designed for
| |
| − | education, competition and entertainment. With it, you can implement diverse interesting
| |
| − | ideas, such as WIFI remote control, automatic avoidance of obstacles, line inspection, take
| |
| − | pictures and record videos, etc. What’s more, in the manual mode, it has first person view
| |
| − | (FPV).
| |
| − | A robot is a machine that can perform some tasks automatically or with guidance. Robotics is
| |
| − | generally a combination of computational intelligence and physical machines (motors). Due
| |

| − | ===HC-SR04 Ultrasonic Sensor Module===
| |
| − | [[Image:Ultrasonic.jpeg|400px|]]
| |
| − |
| |
| − | The HC-SR04 ultrasonic sensor module for Arduino is used for obstacle detection. Ultrasonic
| |
| − | sensor transmits the ultrasonic waves from its sensor head and again receives the ultrasonic
| |
| − | waves reflected from an object.
| |
| − |
| |
| − | [[Image:Ultrasonic1.jpeg|400px|]]
| |
| − |
| |
| − | ====Working Principle====
| |
| − | The ultrasonic sensor emits the short and high frequency signal. These propagate in the air
| |
| − | at the velocity of sound. If they hit any object, then they reflect back echo signal to the
| |
| − | sensor. The ultrasonic sensor consists of a multi vibrator, fixed to the base. The multi vibrator
| |
| − | is combination of a resonator and vibrator. The resonator delivers ultrasonic wave generated
| |
| − | by the vibration. The ultrasonic sensor actually consists of two parts; the emitter which
| |
| − | produces a 40 kHz sound wave and the detector detects 40 kHz sound wave and sends
| |
| − | electrical signal back to the microcontroller.
| |
| − | The ultrasonic sensor enables the robot to virtually see and recognize object, measure
| |
| − | distance and avoid obstacles. The operating range of ultrasonic sensor is 2 cm to 450 cm.

| |
| − | ====Working Principle====
| |
| − | The TCRT5000 IR sensor on the line follower has a TX and RX inside. If a bright color surface is detected in front of the sensor, such as a white paper (about 1cm away), most of the IR rays will be reflected; if a dark color like black surface is detected, most of the rays will be absorbed, while only a small amount will be reflected. The RX will output different analog signals according to the intensity of the reflected IR light.
