Most of mechatronics systems work based on motion or action by means of sort. This motion or actuation is caused either by a torque or force from which displacement and acceleration can be obtained. To obtain this force or acceleration, actuators are mainly used. Actuator is a device which provides enough force needed to start

Potentiometer displacement sensor is a primary sensor which converts the linear motion or the angular motion of a shat into changes in resistance. It is a type of resistive displacement sensor. Linear potentiometers are sensors that produce a resistance output proportional to the linear displacement or position. Linear potentiometers are essentially variable resistors whose resistance

Pneumatic and Hydraulic Actuation Clamps Generally, the above mentioned pneumatic and hydraulic clamps are actuated by mechanical means. Sometimes, these are actuated by hydraulic or pneumatic methods where large production quantities are required. It facilitates faster clamping, uniform and equalised clamping pressure and less operator fatigue. It also provides an accurate controlling over clamping pressure.

Sensors and Transducers Sensors transducers are devices which produce proportional output signal (mechanical, electrical magnetic, ctc.) when exposed to a physical phenomenon (pressure, temperature, displacement, force, etc.). Many devices require sensors for accurate measurement of pressure, position, speed, acceleration or volume. Transducers are devices which converts an input of one form of energy into an

Microprocessor Based Controllers Microprocessors are essential to many of the products we use every day such as TVs, cars, radios, home appliances and of course, computers. Microprocessor based controllers are also called as microcontrollers. Microcontroller is a digital integrated circuit which serves as a heart of many modern control applications. Microprocessors and microcontrollers are similar

Principles of Clamping Principles of clamping devices are used to hold the workpiece in the correct relative position in the jig or fixture. It should ensure that the workpiece is not displaced under the action of cutting forces. For efficient operation, firm clamping of the workpiece is a must. An inadequate clamping may always prove

Bend test is one of the commonly used destructive tests to determine the ductility and soundness (for the presence porosity, inclusion, penetration and other macro size internal weld discontinuities) of the weld joint produced using under one set of welding conditions. There are following two types of bend test: Free bend test Guided bend test

A control system in mechatronics refers to a group of physical component connected or related in such a manner as to command direct or regulate it selfe or another system. The physical components may be of electrical, mechanical, hydraulic, pneumatic, thermal or chemical in nature. Several key terms & elements of the control system are

Mechatronics engineering is a word originated in Japan in 1980s to denote the combination of technologies which go together to produce industrial robots. The word, mechatronics, is composed of “mecha” from mechanism and the “tronics” from electronics. In other words, technologies and developed products will be incorporating electronics more and more into mechanism, intimately and
