Ever since the microcontroller has been invented, automation has been an aspect of technology that very inventor wanted to have in their creation. Automated systems today can be found everywhere. From simple calculators that compute for the mathematical solutions to cars that park in their own, automation indeed has been a common subject for engineers. In this paper, automation was introduced to make a biomedical device out of equipment that has always been present in almost every patients room a dextrose stand. The automated dextrose stand has 4 wheels, 2 of which are powered separately by two DC motors, and the other two by a single servo motor connected to a slider that enables the wheels to turn directions. Proximity sensors are the main sensors of the system that allows obstacle detection and patient-tracking. Four infrared sensors that are capable of 3in. to 5in. detection are used to detect obstacles, and three infrared sensors capable of 1m to 2m detection are assigned to follow the patient. All sensors are connected to a microcontroller, specifically an arduino-based board, which act as the brain of the whole system. The arduino-based board, more specifically called the Gizduino, makes use of all the sensors and adjust the movement of the wheels according to the distance and position of the patient.
