In recent years, technology has been developing rapidly to meet the increasing demand for human needs. Using robotics, human needs are met with speed and accuracy [2]. A robotic arm works by the controls provided by the user or by predetermined commands. The project described here is a robotic arm with 3 degrees of freedom to pick and place objects. The robotic arm is controlled using a mobile application and Bluetooth communication. The robotic arm uses servo motors interfaced with Arduino.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
