Abstract

In this world of science and technology robotics is one of the boom to the world.

Recently, there has been increasing interest in the emerging field of robotics. Todays

robots are mechanical arms controlled by computers that are programmed to perform a

range of handling activities. They are establishing themselves in manufacturing

automation systems to produce a range of goods with great precision. The emerging

era of robots calls for different types of skills. Entering non-industrial areas, the first

fledgling robots for domestic use are coming off the production lines. Robots are being

used in hazardous places, such as outer space or under the sea. Technical advances

are gradually endowing robots with properties that actually increase their similarity to

humans

In this paper, the inventors are going to present an idea of robotics and its

applications in various fields that we come across. With their computational and agile

skills robots perform tasks that are difficult or hazardous to humans. One area where

robots are beginning to excel in, and which causes less controversial debate on their

usefulness, is as explorers.

Introduction

Robotics is the branch of technology that deals with the design, construction,

operation and application of robots and computer systems for their control, sensory

feedback, and information processing. The word robotics was derived from the word

robot, which was introduced to the public by Czech writer Karel apek in his play

R.U.R. (Rossum's Universal Robots), which premiered in 1921. The word robot comes

from the Slavic word robota, which is used to refer forced labor. These technologies

deal with automated machines that can take the place of humans, in hazardous or

manufacturing processes, or simply just resemble humans. Many of today's robots are

inspired by nature contributing to the field of bio-inspired robotics. At present mostly

(lead-acid) batteries are used as a power source. Many different types of batteries can

be used as a power source for robots. They range from lead acid batteries which are

safe and have relatively long shelf lives but are rather heavy to silver cadmium batteries

that are much smaller in volume and are currently much more expensive. Actuators arelike the "muscles" of a robot, the parts which convert stored energy into movement.

spring can be designed as part of the motor actuator, to allow improved force control. It

has been used in various robots, particularly walking humanoidrobots Pneumatic

artificial muscles, also known as air muscles, are special tubes that contract (typically

up to 40%) when air is forced inside them .

Sensors allow robots to receive information about a certain measurement of the

environment, or internal components. This is essential for robots to perform their tasks,

and act upon any changes in the environment to calculate the appropriate response

robotics is a rapidly growing field, as we continue to research, design, and build new

robots that serve various practical purposes, whether domestically, commercially, or

militarily. Many robots do jobs that are hazardous to people such as defusing bombs,

exploring shipwrecks, and mines.

Statement of the Problem

The creation of sensingbot is to determine how the senses of human work and

function well. Moreover, it answers these questions:

1. Can the robot avoid every obstacle heading its way?

2. Can the robot reach to its maximum speed without having any short circuits?

3. What other things can the robot do instead of walking and running?

4. What is the best usage for the robot?

Hypothesis

1. Yes, the main purpose of the robot is to avoid obstacles heading its way. The

robot has built on sensor that could detect obstacle coming its way.

2. Yes, the robot was built with the exact components and had big wheels allowing

the robot to exceed in its speed.

3. The robot was built with special components that when the researcher test it the

sensor will detect it and the buzzer of the robot will turn on.

4. As tested the robot has limited usage only but base on its results and

performance it can be best use for security forces or doing an invest igation. The robots

components like the sensor can be a big help in detecting problems.

Significance of the Study

An IR sensor helps a robot map obstacles, then choose the freest patterns. So it is

usually used for Line-Tracer: A robot that follows a black line drawn on white paper.

The IR sensor consists of a radiation diode and a photo detector. The radiation diode

emits light only when the direction of electric current is orthodromic. The photo detector

can control the volume of the currents depending on how much is intercepts light. Due

to this change of the volume, the photo detector can perceive whether the light comes in

or not.

The IR sensor functions as the eyes of the Line-Tracer which projects and perceives

infrared rays, white reflect them. The Line-Tracer can distinguish black and white by

projecting infrared rays form the radiation diode. The IR sensor can be applicable in

various ways but the Capability of the IR sensor is limited by distance.

You can find the applications of the IR sensor even in our everyday life. Let's look

around and find home appliances. There are diverse appliances that uses IR sensor

such as remote control, an automatic door, an automatic switch, an infrared

temperature detector and so on.

Review of Related Literature

Sensors allow robots to receive information about a certain measurement of the

environment, or internal components. This is essential for robots to perform their tasks,

and act upon any changes in the environment to calculate the appropriate response.

They are used for various forms of measurements, to give the robots warnings about

safety or malfunctions, and to provide real time information of the task it is performing.

A sensor is a device that detects events or changes in quantities and provides a

corresponding output, generally as an electrical or optical signal; for example, a

thermocouple converts temperature to an output voltage. But a mercury-in-glass

thermometer is also a sensor; it converts the measured temperature into expansion and

contraction of a liquid which can be read on a calibrated glass tube.

Sensors are used in everyday objects such as touch-sensitive elevator buttons

(tactile sensor) and lamps which dim or brighten by touching the base, besides

innumerable applications of which most people are never aware. With advances in

micromachinery and easy-to-use microcontroller platforms, the uses of sensors have

expanded beyond the more traditional fields of temperature, pressure or flow

measurement,for example into MARG sensors. Moreover, analog sensors such as

potentiometers and force-sensing resistors are still widely used. Applications include

manufacturing and machinery, airplanes and aerospace, cars, medicine and robotics.

DC motors are inexpensive, small, and powerful motors that are widely used. Gear-

train reductions are typically needed to reduce the speed and increase the torque output

of the motor. It is widely used in robotics because of their small size and high energy

output. They are excellent for powering the drive wheels of a mobile robot as well as

powering other mechanical assemblies. DC motor's direction of movement is

determined by the polarity of the power input. This is an absolute necessity for robotic

functions. Fortunately this type of motor comes in a wide variety of sizes, voltage

requirements, and is available everywhere.

Main CPU is responsible for determining what actions to take. It must be constantly

aware of exact vehicle position in relation to surroundings, including temporary

obstacles. It accepts and interprets encoded speech commands from the speech

processor CPU and sends encoded speech responses to the speech processor for

utterance. The main CPU issues motion commands to the base CPU and requests

reports on motion progress and vehicle status. It also accepts asynchronous

notification of emergency events. Initially, the main CPU will be located off-board. It will

communicate with the vehicle via a serial link, either radio or umbilical cord.

The base CPU is responsible for all hardware on the vehicle base, except the

speech components. This CPU controls the stepper motors and DC drive motors andmonitors their position.

It monitors all bumper and limit switches. When a switch closes, the corresponding

motor is stopped first, then the main CPU is notified of the aborted command. The

battery charge level is monitored, and charging operations proceed under its control.

Distance-to-object and direction-of-sound are calculated by the base CPU. The radio

link to the main CPU, and the LED link to the platform CPU are maintained by the base

CPU. A parallel port connects it to the speech CPU. Base CPU memory is used for

message buffering.

Conclusion

The inventors conclude that the sensingbot is already complete but lack in robotic

parts most especially the camera that symbolizes for the sense of sight like human

have. The robot was one of the genuine products of human brain and as time pass by

different sophisticated robotic equipment and one of this was the IR sensor. In this

simple robot, every students and teachers will realize that a simple IR sensor attached

in different appliances has a lot of function. The IR sensor could be seen in remote

control of televisions, refrigerators, vacuum cleaners, rice cooker, smoke detectors, etc.

The IR sensor just differed in function due to the program that instilled in robot. The

robot was programmed to avoid the edge of the table and an obstacle through

detection. As the creators noticed, the world is run by technology and that type of

technology wouldnt be completed without camera and the robot should be connected in

every smartphones but as a newbie in this type of field, creators were still bridging

towards the world of true robotic system. This robot could be the first step of group inentering the world of robotics.

Recommendations

The inventors recommend to innovate the sensingbot. Innovation includes putting a

camera on it. It can help the sensingbot to avoid the wall or obstacles using a camera

and its infrared sensor. Camera helps a lot on determining the place where the camera

is and can also record the places where the sensingbot have been. In innovating the

sensing bot, the inventors recommend to use smart phones in controlling the robot.

Programming skills are needed in order to control the sensingbot using your smart

phones. Therefore, the inventors recommend further study and improve their

programming and self-learning skills to give the sensingbot more skills than sensing.
