Many people would be confused with the term hexapod robot, but the fact is that it is a robot which moves with the help of six legs. It was an unusual thing because a normal robot used to move on three or four legs. The six legs of the hexapod robot gave it flexibility on a very large scale. If one of the legs of the hexapod robot is not working then this robot has also the capability to walk without it - without any difficulty.
The six legs are not provided in this robot just to make it walk; rather a few of them are provided to help the robot in finding a place to position its foot and at the same time some of the legs are provided to help it in carrying the payload. The basic idea behind creating the hexapod robot was the Hexapod locomotion and the hexapod robots are simply a biological inspiration of this creature. These robots were used to help the scientists in testing the biological theories that were given for the six legged insects.
Many hexapod robots have been designed and most of these robots are scattered all around the universities. This is because of the fact that these robots are not for the personal use and are purely for research purpose. There are a number of designs that are available in the hexapod robots and these different designs are based on the different arrangements of the legs. Such hexapod robots that have been inspired from the insects are laterally balanced while the other such robots are not, one such example would be the Rise robot.
Each leg of the hexapod robot has two to six degree freedom and they are differentiated upon that. In most of the cases, the legs of the hexapod robots are pointed, but this is not necessary. A number of hexapod robots have been made with the legs tipped with some special kinds of adhesives so that they can easily climb the walls.
