In recent week, we have contacted some merchants for 3D printing and quate for the suitable materials.
There are several materials such as H-PLA, PETG or some specific ABS material could be used in our project, which could be bought online, fortunately.
Moreover, some components we ordered delivered and the remained will arrive in the next few days. Especially, we found that Arduino nano, a much more small board, has a similar construction with Arduino UNO, which the code is universal.
Meanwhile, we also have a more clear timetable. On about April 23rd, Yixuan and I are going to meet in Zhengzhou for working on our project until May 7th if the policy not changed and time worked according to plan.
