Introduction
Robots are the packages of the system like electrical, mechanical, the technology of
automation field, and computing that can be used to do many tasks in the domestic and
industrial use. With the increasing development of the robots, the field can be controlled now
the lesser human intervention that is direct to achieve more natural machines interaction.
Some of the application of the robots that utilize recognition of the voice is to help disabled

people by just executing the present command. To process a voice command, the easiest way
is to use the smartphone. The major feature that is normally used is Bluetooth, that allows
the phone to communicate with a robot.
The description and History of investigation of the problem
Many people have been affected just because of working in a harsh environment for
the production of very significant property like for the company which are making lead,
companies which are melting the metals even during operation at a risky environment like
working in high voltages. Hence this voice recognition robot is employed as it will be
instructed by one operator to help in solving these tasks. Therefore this will highly increase
the manufacturing company which will, in turn, boost the economy.
In some industries, it may be very dangerous and very harmful for a human being to operate
on. This can be due to extreme temperature or due to the poisonous environment which may
affect the human normal life (Spolky, 2013. In workshops which contains electromagnetic
waves may expose the workers and individuals which are inside the room to risks of
developing abnormal growth which in many cases results to cancers. Therefore in such
harmful environment robots are highly employed to undertake the production in such
environment.
Solution and the next best solution to the solution of the problem.
A voice recognition, therefore, is employed in such environment to help solve such
adverse problems. With the application of this robot, the production will be higher as
compared to if it was fully done by human being. With this kind of robot. The machine will
easily interact with the man, therefore one operator can command the robot to perform the
production in the industry. The robot will hence interact with the machines in the production

site easily. This will highly increase the rate of production in any set company. For these
robots which are operating in harsh condition, the robot is instructed from outside and
allowed to walk into the workshop and perform the command as instructed (Asimov, 2014).
Voice controlled robotic systems are very beneficial to the areas that are too dangerous
for the human to enter. In some cases voice-controlled robotic systems are controlled using
voice commands received through the android device. These that the after they are issued to
the android application on the phone of the user that is connected to the robots using the
Bluetooth module. The commands will be received by the module after the RF channel is
relayed with the commands. The goal of the voice-controlled robot is to listen to the act of the
commands from the user and then the device after some training will start understanding the
commands (Johnstone, 2015)
Both the speech and recognition of the voice use the human voice recordings but they act
differently. Voice recognition stripes the personal differences in word detection. Recognition
of the speech disregard the meaning of the language to detect physical person behind the
speech (administration, 2013). Robots have some of the characteristics like, ability to sense
environment through giving it some sensors like sensors of the light sonar sensor, sensor
touch and sensor of the chemical. Also, they have the ability to move by rolling wheels
walking and sometimes propelling. Robots are very intelligent, they are able to be smart by
programming so that what it's supposed to do can be clarified. Some of the application of the
robots that utilize recognition of the voice is to help disabled people by just executing the
present command (Iovine, 2014).
To process a voice command, the easiest way is to use a smartphone. With the
incorporation of a higher language artificial Intelligence, this voice recognition robot
generally helps in the provision of the best solution for the above-stated problems (Grimmett,

2012). The diagram below illustrates how voice recognition robot can be employed in
performing different tasks. The one given is employed in the cleaning

The figure 2 below illustrates how the voice recognition robot can be employed in
undertaking several tasks in the environment which is not conducive to human survival.

Parts of the voice recognition robot
Microcontroller: It is a computer on a chip. It combines all the design found in the register
and microprocessor CPU.

Motor Driver IC: It is the amplifier of the current because they provide a high signal of the
currents when low current signals are taken which is used to drive the motor. (derioit, 2017)
Voltage regulator: Is the regulator that is electrical which is designed to keep the level of
voltage constant gotten in devices like computer power supply for stabilizing the voltage of
DC used by the processors (Grimmett, 2012)
Battery: This is the power source for the robot; it can be rechargeable or not chargeable by
solar for the cost reduction
This is the overall representation of the voice control robot, and we can connect every pin of
the microcontroller of the project. The voice control robot is applied in areas such as military
application, wheelchairs, home automation and surveillance device
Software: in this project, the Keil software was used. The Keil C 51 is the most used because
it has many characteristics and also its speed of assembling language is very high. This
language provides many details to all resource of the 8051 microcontrollers.
Conclusion
This report is about the voice-controlled robotic system that is found to be very
beneficial. The robots are the packages of the system like electrical, mechanical, the
technology of automation field, and computing that can be used to do many tasks in the
domestic and industrial use. With the increasing development of the robots, the field can be

interaction. A method to accomplish such is to control the robot through the command.
