Robots

Robots are comprised of different kinds of elements, depending on their purpose. In the industry, the

hand of a robot is referred to as an end effector. End effectors may be expert tools such as spot welders,

spray guns or more common purpose grippers. Common grippers include fingered and vacuum types.

Sensor

The chief element of robotics control technology is the sensor. It is through sensors that a robotic

system gets knowledge of its environment, to which consequent actions of the robot can be adjusted.

Sensors are used to let a robot to adjust to differences in the position of substances to be picked up, to

inspect substances and to monitor appropriate operation. Some robots are able to adjust to differences

in object placement without the use of sensors, provided they have adequate end effector flexibility.

Sensor types

Significant sensor types comprise visual, force and torque, speed and acceleration, tactile and distance

sensors. The majority of industrial robots uses humble binary sensing, analogous to an on/off switch. It

does not permit classy feedback to the robot as to how efficiently an operation was performed. Lack of

acceptable feedback also frequently wants the use of guides and fixtures to make the gestures of a

robot through an operation which implies substantial inflexibility in changing operations.

Automated Robots

Robots are automated either by supervisory or by off-line programming. Most industrial robots are

automated by the previous method. It includes physically managing a robot from point to point over the

stages of a process, with each point kept in the robot control system. By off line programming, tasks are

conveyed over computer commands. It is denoted as manipulator level off-line programming. A major

area of research is the elaboration of off-line programming that makes use of higher level languages, in

which robotic actions are defined by tasks or purposes.

Robots are programmed to travel through a definite continuous path. Continuous path control is

obligatory for tasks like spray painting. Programming moreover wants that a robot be synchronized with

the programmed machine tools or other robots with which it is working. Therefore robot control

systems are commonly interfaced with a more centralized control system. Join in Robotics Courses and

study about how to program robots. It will be really interesting.
