Onmi-directional robot operated by remote control: A robot with four onmi-directional wheels, the application was made for Android cell phones, from which, by connecting via Bluetooth, the robot can be fully operated, the wheels it has allow it to move in a particular way in all areas. addresses; It has a servomotor to display posters or things attached to it and a camera that can connect the cell phone through WiFi and give us "eyes" from the robot. In the future it is planned to replace it with a complete arm to perform assistance tasks, it will have intelligence artificial and the wireless control will be changed to voice commands.

Design, creation and implementation of a display to visualize the number of the song played on the organ in the parish of the German Catholic community of San Miguel Arcángel in Bogotá. The system was designed, manufactured and put into operation, offering continuous technical support, on the organ console there is a keypad that allows the organist to enter the number of the song he is playing, which is transmitted to the display that shows the number so that the assembly can search for said song in their song book. In 2019, the display had an update where the digits were changed to white ones designed and manufactured completely from scratch by me, since these are very difficult to obtain and expensive, this change was made in order to favor the visibility conditions of the community.
