我给你举几个例子以前用过几个本科生都干些什么

1. migrate code to different platform, develop GUI

2. Vendor interaction, maintain consistent fabrication specs for all components and quality control. Has to know the use of instruments for metrology.

3. Machine operator, after training run equipment for repetitive measurement of samples.

其实就是干活，没有什么让你去发现什么的事儿。
