Resumen
A study was realized to develop a system of recognition of gesture commands applied to a mobile robot. To read
the gestures was used the Kinect sensor, which allows to obtain data of the joints of a person's body and to obtain
more precise data of the movements. The research was started making a study of the feasibility of the
development of the system. For this, different data grouping algorithms were searched for them to be used in the
research. We used K-means and Fuzzy C-means algorithms and similar results were obtained between the two
algorithms, although with undefined data the Fuzzy C-means algorithm was able to work with higher efficiency.
It was concluded that using the data grouping technique it would not be possible to work with gestures that had
greater complexity. To solve this problem, the neural networks technique was used, which allowed a greater
robustness of the system, being able to work with more complete gestures. For future work, the use of techniques
such as Deep Learning is used to allow the system to achieve greater performance and to be able to treat
similarities between different gestures, avoiding possible decision errors, which the system developed with
neural networks of a layer faces.
