  3. 3. Introduction Android based robotic arm is designed to provide access to places where human presence must be avoided such as places with very low or very high atmospheric pressure, war zones and even biohazardous places. It can also be used for repetitive and cumbersome works like automobile painting, assembly work in manufacturing processes. The system uses an Nodemcu board that controls the movement robotic arm through Servo motors. The Nodemcu board is connected with a wifi module for wireless connection of android device. An android app is used to provide commands to the robotic arm. This gives the user to work on particular task from a safe distance.
  4. 4. Objective • To design a robotic arm which can be control using mobile app. • Which help us to do dangerous work from a safe place. • Easy to build and low cost. • Easy to operate. • To connect a robotic arm to internet
  5. 5. Methodology • Collection of data from books and internet. • Collection of required components from local market and online shop. • The concept of the design is based on using a microcontroller for processing. • Designing a schematic for creating the circuit board. • Programming for the Nodemcu Setting all the components in a breadboard. • Turn on the device experimental. • And finally, run the using microcontrollers.
  6. 6. Robotic Arm A robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm. The arm may be the sum total of the mechanism or may be part of a more complex robot. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement.
  7. 7. Internet of Things he Internet of Things (IoT) describes the network of physical objects—“things”—that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet. These devices range from ordinary household objects to sophisticated industrial tools.

  17. 17. Future Work • A GSM module with a camera module can be used instead of Bluetooth module to increase the accessible range between the robotic arm and android device. • The App to control the robotic arm can be made for other platforms like IOS and windows. • The end-effector can be made detachable to work with different modules for different applications.
  18. 18. Conclusion The hardware project has performed the basic operations of robotic arm as expected. The main problem to overcome in this project was to interface the Nodemcu board with the android device via Internet. Internet based robotic arm provides remote access to hard-to-reach places and with android based interface it comes under the category of user-friendly projects
