LFR Waiter: Arduino Based Android Application Controlled Waiter Robot

One of the most pressing challenges facing restaurants since the COVID-19 outbreak began is personnel. A staffing scarcity across the business has resulted in a slew of issues, including significantly longer wait times and irritated clients. A robot waiter may make a huge impact in a restaurant in this situation. This research led to the formation of a low-cost Arduino-based Android application control Robot that can work as a restaurant waiter. The proposed model can follow a path, avoid obstacles, serve meals to a specific consumer, and return to the kitchen on its own. To precisely follow the line, the PID algorithm is utilized. To detect potential obstructions, a sonar sensor is used. On an LCD, messages and warnings are displayed. An Android app that allows the chief to select a particular table for serving meals. For convenience, the robot's current state is displayed in the application. Our testing results show that the robot performs satisfactorily over 90% of the time. It should be emphasized that the offered model is adaptable to any restaurant. © 2022 IEEE.

Evaluations of Effective on 5-CH Line Follower Sensor with IoT Simulating Car

Due to the global pandemic of Coronavirus 2019 disease (COVID-19), which began in late 2019, the world has changed and forced all human life to adapt by living in new forms, isolated from the community for both works and learning from their residences. COVID-19 disease undoubtedly has had an impact on the transportation ecosystem. Food, groceries, and even medications are delivered directly from restaurants to customers by deliverers, who can cause exposure and easily infect. Delivery solutions have been proposed and solved through the application of Internet of Things (IoT) knowledge to reduce customer-deliverer exposure. The Internet of Things concept can assist us in developing a mobility object or simulated car that operates without human intervention. The vehicle is programmed to run parallel to the surface of a continuous line, which is referred to as line following. Calibration of the line follower sensor is required to achieve a higher effective tracking accuracy under various conditions, such as line width or rough surface. This research examines and compares how the simulated car behaves when run on various linewidths in preparation for future application and development. © 2022 ACM.

Hospital Assistant Robotic Vehicle (HARVi)

With the advancements of robotic technologies, the medical environments are adopting more and more aspects of automation to enhance the services in hospitals. In pandemic situations such as COVID 19, direct contact with patients may result in the spreading of disease. In this paper we are going to discuss the design and development of an automatic guided vehicle for hospital applications, which can be controlled remotely. Here we are going to specify the design and development of an automatic guided vehicle for hospital applications, which can be controlled remotely. HARVi is a line follower robot, powered by a battery that can be charged from solar energy. © 2021 IEEE.

Design and Implementation of Automatic Line Follower Robot for Assistance of COVID-19 Patients

Coronavirus disease (COVID-19) has caused unprecedented global health problems, and the disease’s spread rate is extremely high. It spreads from infected people (COVID-19 positive) to others via droplets from the mouth or nose when they cough, sneeze, speak, sing, or take deep breaths. Frontline fighters of healthcare organizations such as doctors, nurses, and other medical staff cannot have direct contact with COVID-19 patients in isolation room without personal protective equipment (PPE). Hence, hospital workers have to face different types of problems in distributing foods, medicines, and disposal of waste. An Automatic Line Follower Robot (ALFR) is designed and implemented for COVID-19 patients which is capable of serving infected patients in an isolation room. The main contribution of this paper is to serve essential medicines and foods from the hospital staff and serve it to the patients following the black line. The ALFR also proposes a system which maintains an emergency wireless communication protocol between doctors and patients. It also collects waste from a specified basket and damps it to a proper place. Finally, it can sanitize the isolated room with the help of a disinfectant machine which is assembled in ALFR. ALFR’s performance has significantly improved, and it can successfully complete all tasks. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
