Robots as a new technological tool have advantages and disadvantages. They make an activity safer and easier. For instance, the operator just uses a computer to manufacture a product through a robot and it helps the operator to avoid dangerous situations because he is just controlling it. Likewise, a robot controls quality. This is shown by the following examples, robots are programmed to execute the same task all the time to make sure that the company is going to get the same product result and they are more accurate about measures than an operator. Moreover, a robot performs different tasks faster. For example, a robot can be programmed to perform task like packaging and welding allowing the operator to program the speed of its performance. On the other hand, it isn't self-sufficient. This is illustrated by the fact that a robot can't think by itself. You must send an order to be performed by it and the operator has to supervise its performance to guarantee that the process is going on the right track. Unfortunately, robots have limited movement and sight. This can be seen in these examples, robots can't move as easily as us. They have some degrees of freedom defined by axes to move their joints and also they are blind, so they need human supervision to ensure quality. Finally, a robot is a big investment. For instance, new technology costs a lot and robots are not an exception and they need maintenance once in a while and that involves changing old pieces for new ones too. As a result, robots are a very helpful invention for human beings, but they still have to go a long way to get better results in the future.
