Third generation
Nakano mentioned the third-generation robots, but in years since the publication of his original paper, some things have changed. The two major avenues are developing for advanced robot technology. These are autonomous robot and the insect robot. Both of these technologies are promising for future.An autonomous robot can work by its own. It contains a controller and can do things without supervision, by an outside computer or by a human being. A good example of this type of 3rd generation robot is personal robot about which technophiles dream.There are some situations in which autonomous robots do not work well. In these cases, many simple robots, all are under the control of one central computer, can be used. They function in a similar way like ants in an anthill or bees in a hive
