Watch the full video to have a clear understanding on how I made the robot. Components -   1. Arduino (Any board will do). I recommend Arduino Nano 2. IR sensor - 3x 3. White LED 4. 7805 Voltage regulator 5. Micro SD TF module 6. Micro SD card (Less than 2GB) 7. Servo Motor (Micro Servo sg90) - 3x Download the PCB files from here . Add caption    Talking Principle Let’s talk about the talking part of this robot. Well, robots can’t just start talking by themselves. We can make robots/machines talk by two easy methods – 1. Speech synthesis. 2. Prerecorded audio and For my purpose I chose the 2nd method. Download the Android application to convert text into audio file from here . To process files for arduino go tho this site -  online audio converter Change bit resolution into 8 bit * Sampling rate 16MHZ * Audio Channel – Mono * Then from Advanced option s et pcm format into unsigned 8bit. Then click start conversion. Fact guys – Arduino can’t read from an SD card
