Implementación de un prototipo cortacésped inteligente, aplicando técnicas de visión artificial direccionado a escenarios deportivos.

Abstract

The objective of this research was to implement an intelligent lawn mower prototype by applying artificial vision techniques to use it in sports scenarios. This research was developed in three different stages. For the first stage the Solid works software was used to build the parts and ensemble the prototype. The second stage consisted of controlling the prototype through a remote control, the communication was managed by applying a mobile application and a Bluetooth model for a controller AT mega 2560 of Arduino; in addition, a human machine interface (HMI) was used so the user could interact with the prototype, in this way a visual monitoring could be made to the obtained variables through sensors and a data acquisition camera, which means that it only activates the cutting system when the variables assimilate a grass surface. Finally, the third stage consisted of the transformation of the lawn mower prototype in autonomous by using visual artificial techniques; for this purpose a sensor was used to obtain and process images, the sensor is called PixyCMcam5. This last stage was more difficult to design and control due to the hardware variety, the software, and the new techniques which needed to be integrated so that this prototype could be developed. It is concluded that the prototype is accessible to the local market, its electric motor is friendly with the environment, and the height of the blade is variable since it works with a lifting mechanism which enables its cutting action in various fields. The crucial point is the addition of the modeling system to the prototype since there is not any device in the market with the needed characteristics, this means a device which uses vision techniques to cut and shape the grass at the same time. This prototype is safe, reliable, cost-effective, ease to use, effective, efficient, and durable. It is recommended to perform the prototype electric system maintenance monthly.
