1. Industrial
Robots

2. ֎Introduction
The word robot was invented in the 19th century
and comes from the Czech word robota, meaning
drudgery or slave-like labor.
Its a machine capable of carrying out a complex
series of actions automatically, programmable,
that is to say, a machine resembling a human being
and able to replicate certain human movements and
functions automatically.
A robot consists of electric, electronic and
Mechanical. The Robots are very good for
certain functions, because unlike humans never get
tired, or fatigued and can work in dangerous conditions,
without air and without the easily distracted.

3. The first modern industrial robots, called
Unimates,
were developed by George Devol and Joe
Engelberger in 1959.
Unimate #001 prototype was installed on an
assembly line for the first time at a General
Motors diecasting plant in Trenton, New Jersey.
By 1961, the Unimate 1900 series
became the first mass produced robotic arm
for factory automation.

4. Main components of Industrial Robots
•Controller
•Arm
•End Effector
•Drive
•Sensor

5. »Controller
 Brain of the industrial robotic arm and allows the parts of the
robot to operate together.
 The robotic arm controller runs a set of instructions written in
code called a program.(usually C/C++/Python)
 The program is inputted with a teach pendant.
 Many of today's industrial robot arms use an interface that
resembles or is built on the Windows operating system.

6. »Robot arms
 Industrial robot arms can vary in size and shape.
 The industrial robot arm is the part that positions the end ffector.
 With the robot arm, the shoulder, elbow, and wrist move and
twist to position the end effector in the exact right spot.
 Each of these joints gives the robot another degree of freedom.
A simple robot with three degrees of freedom can move in three
ways: up & down, left & right, and forward & backward.
 Many industrial robots in factories today are six axis robots.

7. »End effector
 The end effector connects to the robot's arm and functions as a
hand.
 This part comes in direct contact with the material the robot is
manipulating.
 Some variations of an effector are a gripper, a vacuum pump,
magnets, and welding torches.
 Some robots are capable of changing end effectors and can be
programmed for different sets of tasks.

8. »Drive
 The drive is the engine or motor that moves the links into their
designated positions.
 The links are the sections between the joints.
 Industrial robot arms generally use one of the following types of
drives: hydraulic, electric, or pneumatic.
 Hydraulic drive systems give a robot great speed and strength. An
electric system provides a robot with less speed and strength.
Pneumatic drive systems are used for smaller robots that have
fewer axes of movement.
 Drives should be periodically inspected for wear and replaced if
necessary.

9. »Sensors
 Sensors allow the industrial robotic arm to receive feedback
about its environment.
 They can give the robot a limited sense of sight and sound.
 The sensor collects information and sends it electronically to the
robot controlled.
 One use of these sensors is to keep two robots that work closely
together from bumping into each other.
 Sensors can also assist end effectors by adjusting for part
variances.
 Vision sensors allow a pick and place robot to differentiate
between items to choose and items to ignore.

10. Advantages of Industrial Robots
1. Increased efficiency
Industrial robots are able to complete certain tasks faster and better than people,
as they are designed to perform these tasks with a higher accuracy level. This and the
fact that they are used to automate processes which previously might have taken
significantly more time and resources, means that you can often use industrial robots to
increase the efficiency of your production line.
2. Higher quality
Due to their high accuracy levels, robots can also be used to produce higher quality
products which adhere to certain standards of quality, whilst also reducing the time
needed for quality control.
3. Improved working environment
Industrial robots are often used for performing tasks which are deemed as dangerous
for humans, as well as being able to perform highly laborious and repetitive tasks.
Overall, by using industrial robots you can improve the working conditions and safety
in your factory or production plant. Robots don’t get tired and make dangerous mistakes,
neither do they suffer from repetitive strain injury.

11. 4. Increased profitability
By increasing the efficiency of your production process, reducing the resource and time
needed to complete it, and also achieving higher quality products, industrial robots can thus
be used to achieve higher profitability levels overall, with lower cost per product.
5. Longer working hours
Typically people have to have breaks, get distracted and after time attention drops and pace
slows. With a robot it can work 24/7, and keeps running at 100%. Typically if you replace one
person on a key process in a production line with a robot the output increases by 40% in the
same working hours just because a robot has more stamina and never stops. Robots also
don’t take holidays or have unexpected days off sick.
6. Prestige
You set yourself at the cutting edge of your industry and wow your customers when they
come to see you. As a marketing tool robots are fantastic, boost your brand image, and have
often been used simply for the PR even if they don’t offer many benefits over a bespoke non-
robotic system.

12. Disadvantages of Industrial robots.
1. Capital cost
Whilst industrial robots can prove highly effective, implementing them might require a fairly
high capital cost. That’s why, before making a decision we recommend considering both the
investment needed and also the result you expect to achieve.
2. Expertise
Whilst industrial robots are excellent for performing many tasks, as with any other type of
technology, they require more training and expertise to initially set up. The expertise of a
good automation company with a support package will be very important. To minimize your
reliance on automation companies you can train some of your engineers on how to program
robots, but you will still need the assistance of experienced automation companies for the
original integration of the robot.
3. Limitations
In recent years the number of industrial robots and the applications they can be used for has
increased significantly. However, there still are some limitations in terms of the type of tasks
they can perform, which is why we suggest that an automation company looks at your
requirement to assess the options first.

13. Sometimes a bespoke automated system may give a better or faster result than a robot. Also, a
robot does not have everything built into it, often the success or failure of an industrial robotic
system depends on how well the surrounding systems are integrated e.g. grippers, vision
systems, conveyor systems etc. Only use good trusted robot integrators to be sure of the
optimum results if you do choose to use industrial robots.
