Delivery Robot for Food Medicine and Medical Supplies Controlled Via a Smartphone

Abstract

The objectives of this research were: 1) to develop a robot to deliver food, medicine and medical supplies controlled via a smartphone, 2) to determine the efficiency of the robot on delivering food, medicine and medical supplies controlled via a smartphone, and 3) to study the satisfaction of Robot users on delivering food, medicine and medical supplies controlled via a smartphone. The research model is an experimental research with the conceptual framework of remote control via Wi-Fi.  The research area was at Surat Thani Hospital. The sample consisted of 20 medical staffs and patients who used the services of Surat Thani Hospital derived by purposive sampling technique. The research instruments included a delivery robot, efficiency recording forms, and satisfaction assessment forms.  Data were analyzed using statistical values, percentages and mean.

The results of the research showed that: 1) the robot structure consisted of 3- operational systems, namely, the drive system working on 2 -front wheels with a DC motor as a power transmission. The motion control system controls the robot with a smartphone via the Blynk application. The user communication system employed the video call on the tablet. 2) The performance of the communication between smart phones, smartphones with IP cameras, tablets and drive systems has the highest level of accuracy within the distance of not more than 40 meters from the broadcasting device when controlling the robot via a smartphone. It was found that the performance of the drive system was at the highest level correlated with the direction control via the Blynk application on a smartphone. In addition, the average distance that the robot traveled was 1,106.2 meters per battery charge.  3) The overall satisfaction assessment results reached the high level of satisfaction.
