Abstract
The COVID-19 pandemic has had a significant impact worldwide, impacting schools, undergraduate, and graduate university education. More than half a million lives have been lost due to COVID-19. Moving towards contactless learning activities has become a research area due to the rapid advancement of technology, particularly in artificial intelligence and robotics. This paper proposes an autonomous service robot for handling multiple teaching assistant duties in the educational field to move towards contactless learning activities during pandemics. We use SLAM to map and navigate the environment to proctor an exam. We also propose a human–robot voice interaction and an academic content personalization algorithm. Our results show that our robot can navigate the environment to proctor students avoiding any static or dynamic obstacles. Our cheating detection system obtained a testing accuracy of 86.85%. Our image-based exam paper scanning system can scan, extract, and process exams with high accuracy.

With the widespread COVID-19 pandemic nowadays, people are more concerned about protecting their families, making them less willing to interact with others to avoid virus transmission
We proposed an autonomous voice-controlled service robot capable of navigating classroom environments, interacting with students, proctoring exams, and scanning exam papers rapidly
Summary
With the recent advancements in computer vision and artificial intelligence, service robots are becoming increasingly involved in our daily lives. Both students and instructors may benefit from the employment of robots. A robot may help students by acting as a tutor, and it can help instructors by working as a teaching assistant [1]. One characteristic that makes a service robot promising as a teaching assistant is its ability to move and perform repetitive physical activities [2]. The primary duties of a teaching assistant include exam proctoring, communicating with the students, and delivering tutorials. With the widespread COVID-19 pandemic nowadays, people are more concerned about protecting their families, making them less willing to interact with others to avoid virus transmission
