The use of Automated Handling Mechanisms have several advantages, including not only increasing productivity but also enhancing products' quality and saving human life, as well as reducing running cost. Manipulating hazardous objects is one of these activities that need such automated systems. This automated process requires successive operations; it is attacking, holding, manipulating, and then releasing. The good enough precision with reasonable speed provide several benefits such as increasing productivity, improving the quality and saving human life when manipulating with himself such hazardous objects.

A continuously variable transmission (CVT), also known as a shiftless transmission, single-speed transmission, stepless transmission, pulley transmission, or, in case of motorcycles, a 'twist-and-go', is an automatic transmission that can change seamlessly through a continuous range of effective gear ratios. This contrasts with other mechanical transmissions that offer a fixed number of gear ratios. The flexibility of a CVT with suitable control may allow the input shaft to maintain a constant angular velocity even as the output speed varies.
