Development of obstacle- avoiding robots using RF technology

Abstract

Purpose In the capricious span of this current millennium, there is a deafening roar in the demand for modernization in the sector of robotics and technology to perform tasks in an intelligent manner. Thus to replenish such necessities, the innovations and inventions of researchers came forward as blessings on human civilization due to their sheer ingenuity and relentless and arduous efforts with each nanosecond passed from now onwards. With the same sublime goal, same resilient endeavor, same aggressive demeanor, the paper on obstacle avoiding robots comes forward. The paper aims to discuss these issues. Design/methodology/approach It exhibits how to control a differential drive robot wirelessly by analog thumb joystick module with added obstacle avoidance protection. The variations made by the user in the control of analog thumb joystick module are fed as input to the Atmega 16 microcontroller board which further transfers it wirelessly to the robot through the radio frequency (RF) transmitting module. The Arduino mega microcontroller equipped to the robot cross-checks the instructions gained through the RF receiving module and provides power accordingly to the geared motors through the motor driver board for movement along with scanning the environment to avoid obstacles present thereby. Findings The improvisation of RF technology in controlling the obstacle avoiding robot has enhanced its application and reliability by leaps and bounds reducing the anxiety and tension of the human controller. Originality/value With more advanced algorithm and genuine deployment sensors, the idea behind this research work can be used in humanoid robots which can help immensely in going to the extremely dangerous terrains, war zones and also in human rescue operations.
