Abstract

Covid-19 pandemic has caused many problems in the country's healthcare system. With the availability of the sophisticated technologies, health facilities are required to be emphasized to assist in medical practices. Therefore, a low-cost robot is designed and developed to assist in simple task, which aims to design and develop a low-cost robot for the medical industry. The main goal is to build a robot to help with delivering medicine. Three (3) Designs of Experiments (DoE) are carried out to examine various facets of the robot's operation. DoE 1is emphasized on the robot movement on various surfaces. From DoE 1, it is found that, the proposed robot can move steadily on flat, smooth surfaces but erratically on flat and rough surfaces. DoE 1 is essential to ensure optimum movement performance that able to run on various surfaces at the medical facilities. DoE 2 concentrated on the ESP32 module and the Blynk IoT platform's Wi-Fi capabilities. Based on the signal intensity from mobile hotspots and home Wi-Fi, the Wi-Fi connection's range has shown a robust connectivity within a range of 0–10 metres from both networks, albeit the signal strength decreased as the distance rose. This emphasises on how crucial proximity in maintaining a trustworthy relationship. Four Infra red (IR) sensors for reading branches and one ultrasonic sensor for obstacle detection are tested as part of DoE 3. The findings have shown various branches can be tracked and detected successfully. Overall, the project has been succeeded in creating an affordable medical support robot with promising outcomes for mobility, Wi-Fi connectivity, and sensor functioning. Further study and testing are recommended to enhance the robot's ability to recognise obstacles and guarantee safe navigation in medical settings.
