What is a Robot?
Robot is a system that contains Sensors, Control systems, Manipulators, Power
Supplies and software all working together to perform a task.
Definition
(According to the Robot Institute of America):
A robot is defined as a reprogrammable, multifunctional manipulator designed to
move material, parts, tool or specialized devices through various programmed
motions for the performance of a variety of tasks.
From this definition, it is clear that a single robot can be made to do a variety of
tasks like cutting, spraying and welding by merely changing that toll end.
Manipulator is the mechanical moving structure that performs the tasks for which
it has been programmed.
Characteristics of a Robot
A robot has these essential characteristics:
(1) Sensing
First of all your robot would have to able to sense its surroundings.
Giving your robot sensor: light sensors (eyes), touch and pressure
sensors (hands), chemical sensors (tongue) will give your robot
awareness of its environment. Touch sensory signals can be
generated by the robot's own movements. It is important to identify
only the external tactile signals for accurate operations. Previous
solutions employed the which relies on the prior knowledge of
signal statistics that are assumed to be stationary. Recent solution
applies an adaptive to the robot’s logic It enables the robot to
predict the resulting sensor signals of its internal motions,
screening these false signals out. The new method improves
contact detection and reduces false interpretation.
(2) Movement
A robot needs to be able to move around its environment. Whether
rolling on wheels, or walking on legs, a robot needs to be able to move.
(3) Energy
A robot to be able to power itself. A robot might be solar powered,
electrically powered or battery powered.
(4) Intelligence
A robot need some kind of smarts. A programmer is the person who
gives the robot its smarts.
Goals of a Robot in Industry
Increasing productivity,
Reducing Costs,
Overcoming Shortages of skilled Labor,
Providing Flexibility in Manufacturing Operations,
Improving product quality and
Freeing Human beings from Boring and Repetitive tasks.
Application of Robots
Some applications of Robots are:
(1) In Vehicle and Car Factories
They can be used in precision Cutting, Oxygen Cutting, Lasers etc.
(2) In Mobile Phones
Mounting Circuits on Electronic Devices.
(5) In manufacturing
To help make stuff, faster and with more quality control.
(8) In toys
Very simple Robotic techniques are used in toys for children.
(2) Manipulator
The manipulator is the arm itself, which may be inflexible or
joined with a sliding or rotary joint, like the elbow of a human
arm.
(3) End-Effector
The end-effector is the hand connected to the robot’s arm. It is
often different from a human hand – it could be a tool such as a
gripper, a vacuum pump, tweezers, scalpel, blowtorch - just
about anything the helps it do its job.
(4) Actuators
An actuator is a type of motor that is responsible for moving or
controlling a robot. It is operated by a source of energy, typically electric
current, hydraulic fluid pressure, or pneumatic pressure and converts
the energy in to motion.
(5) Sensor
Most robot of today are nearly deaf and blind. Sensors can provide
some limited feedback to the robot so it can do its job. Compared to the
senses and abilities of even the simplest living things, robot have a very
long way to go.
The sensors send information, in the form of electronic signals back to
the controller. Sensors also give the robot controller Information about
its surroundings and lets it know the exact position of the arm or the
state of the world around it.
Advantage of robots
Safety. Safety is the most obvious advantage of utilizing robotics.
Speed. Robots don't get distracted or need to take breaks.
Consistency. Robots never need to divide their attention between a
multitude of things.
Perfection. Robots will always deliver quality. ...
Happier Employees.
Job Creation
Productivity.
Advantages of Industrial Robots
Increased efficiency
Industrial robots can complete certain tasks faster and more efficiently than
humans as they are designed and built to perform them with higher accuracy. This
combined with the fact they are used to automate processes which previously
might have taken significantly more time and resource results in the use of
industrial robots to increase the efficiency of production lines.
Improved quality
Given their higher levels of accuracy, industrial robots can be used to produce
higher quality products which result in the reduction of time required for quality
control and ensures that standards of quality are adhered to.
Increased profitability
The results of introducing industrial robots can only ensure higher profitability
levels with lower cost per product as by increasing the efficiency of your process,
reducing the resource and time required to complete it whilst also achieving higher
quality products, introducing industrial robots save money in the long run.
Prestige
“Wowing” your clients by operating at the cutting edge of your industry, robots are
even fantastic as a marketing tool, boosting your brand image and are regularly
used simply for PR if they don’t already over enough benefits!
Expertise
The initial set up of industrial robots requires a lot of training and expertise as with
any other type of technology, this is because they are excellent for performing
many tasks. Good automation companies provide a support package of their
expertise which is an extremely important factor. However, to minimise reliance
on automation companies, training can be given to engineers to allow them to
program the robots – though the assistance of experienced automation companies
is still required for the original integration of the robot.
Limitations
The number of industrial robots has seen a dramatic increase over the years but
there are still some limitations to the type of tasks they can perform. This is why
we advise that companies liaise with automation companies prior to
implementation to assess the various options available first. Some may give a
better of faster result than a robot. A robot does not have everything built into it so
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. Use only good trusted robot integrators to ensure optimum results.
Conclusion
Careful consideration and advice should be sought before investing in robots. The
aim of this blog was to give you some insight into the aspects that should be
considered before implementing industrial robots in your company, we hope it has
been successful in doing so. If more guidance is required or you would like to find
out more on the benefits of industrial robots and how they can best be applied to
your project, contact our team of automation .
