To overcome the problems interconnected with manual involvement in production operations, it is essential to step towards automation. One such sector where manufacturer is focusing is on programmable robots. Robot is an electromechanical device which is used to do the specified work prescribed by the human beings. First robot was invented by George devol in 1954.
Robots are controlled with the help of computers; the desired work is programmed with the alphanumerical language and prescribed to the robot. Applications of the robots mainly include machining, assembly operations, pick and place industrial components with accuracy and high precision.

The change burr is that the commonest. Burrs is also classified by the physical manner of formation. natural action or re-deposition of fabric leads to a recast bead. Incomplete cut-off of fabric causes a bring to an end projection. Burrs generally is reduced by considering materials, form and process within the style and producing engineering phases of development. Burrs in trained holes cause fastener and material issues. Burrs cause a lot of stress to be targeted at the perimeters of holes, decreasing resistance to fracture and shortening fatigue life. They interfere with the seating of fasteners, inflicting harm to fastener or the assembly itself. Cracks caused by stress and strain may end up in material failure. Burrs in holes additionally increase the danger of corrosion, which can flow from to variations within the thickness of coatings on a rougher surface. Sharp corners tend to concentrate electrical charge, increasing the danger of static discharge. Burrs in moving components increase unwanted friction and warmth. Rough surfaces additionally end in issues with lubrication, as wear is accrued at the interfaces of components. This makes it necessary to switch them a lot of ofttimes. Electrical charge build up will cause
