Development of Mobile Robotic Arm for Object Identification and Retrieval Interfaced with IoT

The main aim of the project is to develop a mobile robotic arm to identify the specified object and segregate it. The robot traces a predefined path and segregates the objects placed along thepath. The 3 DOF robot is controlled by an Arduino MEGA controller. The chassis of the robot is driven by four wheels controlled by DC motors and drivers circuit. The robotic arm made of acrylic material is fitted above the chassis to perform the pick and place operation. The robotic arm has two degrees of freedom which is achieved by two servo motors. A mechanical gripper is used as the end effector which is also controlled by the servo motor. The object identification is done by using a web camera interfaced to MATLAB software. Implementing the application of IoT, feeding the color of a desired object from a mobile phone application, using Wi-Fi communication it is communicated to the Arduino. Once the specified object is identified, a control signal is sent to the robotic arm from the controller to pick and place it in the pallet. This robot can be used in a wide range of applications like packing, palletizing, warehouse automation, etc.
