Inverse Kinematic is a big mathematic problem when is necessary to find different angles of different joints of a robotic arm. Calculating theta different angles values is not a simple question, because is necessary to use different matrix conversions and linear expressions to define the right results. When the use of mathematical techniques spends much effort another way to find this answer is use computing resources like Genetic Algorithms. This paper aim use Genetics Algorithms to define each theta values to 5 different values of robotics join arm.
