Abstract

This study explores the use of IoT technology to enhance communication between Android smartphones and sumo robots, aiming to overcome the limited range of Bluetooth connections. By utilizing the NodeMCU ESP8266 microcontroller, the researchers achieved a connection speed of 4.6 seconds. Furthermore, the step-down circuit test with a 5Vdc power supply and the LiPo 3-cell battery test with a 12.54Vdc power supply yielded positive results. The Bts7960 driver was also successfully tested for clockwise and counterclockwise rotation. Finally, the maneuver test using the Blynk software showcased the robot's ability to respond to four commands—forward, backward, turn left, and turn right—via the IoT system. Highlights: Enhanced communication: Utilizing IoT technology enables improved communication between Android smartphones and sumo robots, expanding the range beyond the limitations of Bluetooth. Efficient connection: The implementation of the NodeMCU ESP8266 microcontroller achieves a speedy connection with a response time of 4.6 seconds, facilitating seamless remote control of the robot. Versatile maneuverability: With the Blynk software and IoT system, the sumo robot can execute four essential commands—forward, backward, turn left, and turn right—providing flexibility and control during operation Keywords: Sumo robot, IoT communication, Android smartphones, NodeMCU ESP8266, Blynk software.

Abstract

In the context of the widespread transmission of Covid-19 via various mediums, including physical contact and contaminated surfaces, the critical need for document sterilization becomes apparent. Addressing this concern, a Document Sterilization Box was developed utilizing Ultraviolet-C (UV-C) Light and Heating methods, integrated with an Arduino Uno system equipped with LCD, LED displays, and a Buzzer for remote monitoring. The study aimed to assess the efficacy of this approach, achieving successful results with an average Lux reading of 204.6 and a temperature of 31.9 ̊C, within a 2-minute timeframe and humidity of 111.3%. The Document Sterilization Box employing UV-C Light and Heating proved to be a highly effective, safe, and environmentally friendly method, eliminating 100% of harmful microorganisms without causing damage to the exposed objects. This innovation offers valuable implications for enhancing hygiene practices and safeguarding public health on a global scale. Highlight: Emerging Necessity: Recognizing the critical need for effective document sterilization due to Covid-19 transmission via various mediums, including contaminated surfaces and physical contact. Technological Innovation: Introducing a Document Sterilization Box incorporating Ultraviolet-C Light and Heating methods, enhanced by Arduino Uno system, LCD, LED displays, and remote monitoring capabilities. Efficacy and Implications: Successfully achieving high efficacy in eliminating harmful microorganisms, the UV-C Light and Heating approach offers a safe, eco-friendly solution with global implications for elevating hygiene standards and preserving public health.
