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. 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. 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. 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. 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.
15. Advantage
1. Low cost
2. Easy to build.
3. It helps during the time when we are work using dangerous materials,
explosions, chemical and massive heat.
4. Too much accuracy. We can operate the arm at one degree angle.

Cost Analysis
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. 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
