Detecting and avoiding obstacles has been a vital role that has been played by the bots that are created using Arduino. The table bot is a well known bot in the realm of small Arduino operated bot that are also easy to construct. It senses if there exists a base ahead of the path on which the bot currently is. The bot will turn and change its course whenever it reaches the edge of the table it is running on. It does that using the infrared sensor also commonly known as the IR sensors. IR sensor is guided by the Infrared technology which addresses a wide variety of wireless applications. The main areas are sensing and remote controls. In the electromagnetic spectrum, the infrared portion is divided into three regions: near infrared region, mid infrared region and far infrared region. The basic concept of an Infrared Sensor which is used as Obstacle detector is to transmit an infrared signal, this infrared signal bounces from the surface of an object and the signal is
