Quarantined at home because of COVID19 - how can I do engineering research productively?
You can try to fill the gaps in your knowledge and skills. For example, learn some techniques that are commonly used in your field. Even if you will not need them for your immediate project, there is a chance that they will be useful for the next one. For example, if you do engineering, you are likely to need to write some code, so you can improve your software engineering skills. Your colleagues may give you some more ideas on what is useful to learn.

If you feel sick of reading papers alone, you might try to reach to other junior students and form a virtual study group where you discuss and critically analyze recently published papers. You may actually come up with some ideas for research project based on the discussions. Good luck!
