"1.Pneumatics is scientific modification which deals with the presentation of vapour in apressurized form for the development of this motorised movement. Pneumatic has providedmuch more complex work in a simpler way which was earlier thought as task done by themachines only. Features of pneumatics is usually for the inert gas to process pneumaticsystem bearing in mind that there should be no escape of the inert gas out of the systembecause for the non-static pneumatic system carbon dioxide is used and since hydraulicsmethod is used in the pneumatics system carbon dioxide is used in its compressed form. Pneumatic robots are less expensive and it already has the supressed air system inthem. Filing, packaging, door control, stacking ,dentist drilling and HVAC control system arethe various activities for which the method of pneumatics is widely used it is also usedbecause of its nature which is reliable and simpler in its design and is safe while in use.2.A servo system is a method to boost the machine with an electric amplifier and alongwith it is monitored for its signal feedback and also adjusting for the expected amount ofquality and work activity. A robot with oscillating parts has a servo system for its control andit helps the speed of the motor part when the load fluctuates. Most of the machines are dependent on the servo system in the manufacturingindustry and contemporary and modern servo system not only helps in the movement of therobot but also detects and checks if there is any unnecessary movement hence the level ofaccuracy is kept in checked. Servo system generally detects and keeps in check the mistakethat can be measured in the right way. 3.The last part of a robot’s arm is held by technique of end effector which is used forlifting, turning, holding and other usage generally done by a human hand. End effectors havefingers generally which has no control and they are like rambling fingers which is not able ofidentify any shape and they are less hard working in nature but it is highly economical todevelop it. The second category is the use of end effectors in the electro magnetics and vacuumcups which are tailor made devices that work as end effectors.4.Robots lack the sense of sight and sound and they are limited with their own ability toperform tasks, but it has provided enough scope for providing the same .the most crucial isthe sensing part on the grippers which is used for sending signals to the controller oftheservo to exactly know the position of the arm of the robot. The entire method is lead withspecific commands and only through this a robot identifies whether it is in touch with anyother object or not.5.End effectors are crucial parts of the robot system since it helps in the end route that isstarted from the control. Robots are designed and made for different purposed and endeffectors regulate the working ability of the robot in any given task to perform. The designersof an end effector must bear in mind that the end effector has the capability to spread itsworking part, whether or not the gripper is functional or not at the end piece of the endeffector. Yet another part that needs to be considered is that it should not deform the workingparts since certain parts may be delicate and can be twisted easily. The end effector is a gripper which should remain steady and able to control itself by the sense of positioning.Other points that needs to be kept in mind is the amount of friction, the weight of the part andthe speed of the robot arm so that there is no breaking or dropping of the working part whenin motion.6.The gripers used in vacuum cups should be free from iron and it should be clean, flat,smooth and non-porous in nature. Vacuum cups are made of soft rubber plastic material andis used to create vacuum. This works on the principle of the vane device which produceshigher level of vacuum and it pushes to create suction that is held by the suction cup. Vacuum grippers are limited in it way of working since it cannot perform where theobject is curved and angled and has no flat surface ,also dirty and porous and corrugated orgrooved surface hinders the vacuum gripper to performsince these limitations has airtrapped inside them. Yet another limitation is glass which can’t be held by vacuum grippersand they tend to leave marks on the glass by the vacuum grippers and hence it increases thecost and also the processing time.7.Compliance is the ability to balance and bear for the parts which is not aligned in anactive or passive strategy. A robot is operates in a modified form and depends on forcesensor’s output in an active compliance while it involves the deforming of a flexible gripperwhen slightly nonaligned is when it in passive compliance.The compliance of an end effectorcan be efficiently put to more work if free links are added to the end effector to allow for awider control of the bandwidth. 8.Articulated arm type robots: robot armModel name: R17 Manufacturer: ST RoboticsApplications: long reach machine access, laboratory applicationsNumber of axis: 5Payload: 5 kgURL: http://www.strobotics.com/SCARA type robots: robot arm\\Model name: RHF SCARAManufacturer: Allied automationApplication: long range handling, packagingNumber of axis: 6Payload: 2-20 kgURL: http://www.allied-automation.com/partners/mitsubishi-electric/robots/Gantry (Cartesian) type Robots: robot armModel name: F9600N"
