Question B (30 marks)As robots and AI algorithms continue to improve, they will be increasingly used in many domains. Ina 2019 report, the World Economic Forum has noted that this will include education, including atuniversity level.Write a short article about the current state of robotics used in the context of education. This caninclude education at any age, from nursery school children to university, or informal learning outsideof the classroom. You may include robots that are commercially available or that exist as prototypes.You may also wish to comment on any market failures and explain why such services may havefailed.Write no more than 700 words.Your article should be based on the following plan.
Part 2
Give three examples of robots designed for use in education. For each example, you shouldoutline the tasks the robot can complete.(3 marks)Give a brief description of each robot, referring to concepts and topics discussed in therobotics block. You should cover four elements for each robot, such as the level of autonomy,the sensors used, the actuators used, how the robot is powered or how ‘intelligent’ the robot is.(12 marks)Briefly discuss how a student is intended to interact with each robot. Among these robots,highlight one form of interaction you feel would benefit the learner, and one you feel would bea shortcoming.(5 marks)Briefly discuss any social, legal, economic or ethical issues associated with using robots in thecontext of education.(4 marks)Give references to the sources of your information. Use the Cite Them Right Harvard style.(3 marks)Marks will also be allocated for the overall quality of your writing in this question (including clarity,structure, spelling, punctuation and grammar).(3 marks)Question C (30 marks)Before Linux existed, an operating system named MINIX was developed by Andrew Tanenbaum.Although over 30 years old, the MINIX operating system is still running.Read the following article (and watch the associated video at https://www.youtube.com/watch?v=eKYh0wjhXJk&list=PLn0nrSd4xjjbIHhktZoVlZuj2MbrBBC_f) by Prof Tanenbaum that discuss thisproject: Lessons Learned from 30 Years of MINIX.26/04/2021, 23:37Page 7 of 11
Using this article, write a report on MINIX. Write no more than 700 words.You may have to find and use additional source material to answer the question; if you do so, thenyou must provide references.In your report, you should do the following.Explain what MINIX was designed for. Discuss the relationship between MINIX and Linux.(3 marks)State four lessons learnt regarding the development of MINIX that are identified in the article.For each lesson, discuss its relevance to the development of operating systems today.(12 marks)Describe what a microkernel is and how it differs from a monolithic kernel. Discuss oneadvantage and one disadvantage of using a microkernel.(6 marks)Discuss whether you believe the MINIX project was a success. Justify your answer.(4 marks)
