Cobots as “an apparatus and method for direct physical interaction between a person and a general-purpose manipulator controlled by a computer”. The first cobots that were developed guaranteed human safety by having no interior source of motive power. In its place, motive power was offered by the human being. Cobots was invented with a function to allow computer control of motion, by cooperatively redirecting a payload with a human worker.
Cobot are special robots designed using continuously variable transmission (CTVs) as an alternative traditional motor driven links. It’s a good-looking option for telerobotic controllers in the sense that they are secure in contacting human being and are able to a high-quality virtual surfaces that is able to oblige the motion suitable for directions of telerobotic task completion. Cobot was designed using solid work CAD. Its significant to take into consideration that the force of gravity influence and define factor that led to each cobot design.
Using high gear cobot design seems to be the only way to design cobot that can life up to 10 or 100s of kg and that is also capable of articulating like human hand. The gear ratios are to be high for cobot to support itself, lift a load, work like human arm, and with satisfactory complete weight. Cobot is design in such a way that majority of useful postures of the cobot need that two of his arms enable the arms to support both the load in the gripper and the cobot joint itself. Regrettably, the reduction of high ratio gear in cobot design have a major side effect when it comes to cobots.
