A Bluetooth robotic arm is used to reduce the errors made by humans and also minimize their efforts. Around the globe, with upcoming technologies, robotics provides improvements in various engineering departments for a use case. There is a need to communicate with the robot remotely in order to control its movements and pass critical data—a mechanical arm with a movable base controlled by an application through Smartphone via Bluetooth. A robotic arm can function similarly to the human arm as specified by the controller or can be used for automation purposes. Listed below are the best libraries that can be reused and create a custom robotic arm.
