Questions like, "What is polycarbonate glue?" somewhat amuse me. Maybe it's because I have had years of experience doing fabrication while kids are new to the process. So let me explain. This goes for items in the minibot list, like the allowable cements and "household light switches".

Quite specifically, if you go to a commercial supplier of sheet plastic products, on the shelf by the order counter, you will find bottles of glues called "Polycarbonate Cement" and "Acrylic Cement". Such products are what fulfill the definition as listed in the allowable parts list, just as PVC cement is what comes in the can called PVC Cement that you get in the plumbing department of the local hardware or building products store. It's that simple.

This isn't really rocket science, guys. Stop trying to make it difficult. Stop trying to run around looking for loopholes and work within the Game Design Committee limitations on construction. In the real world, those limitations are called "specifications" and they are what the customer pays you to use when you design the project you are selling them.

As a robot inspector, I'll accept any glue which specifically says in its literature that a recommended use is to glue polycarbonate, but if it isn't real polycarbonate cement, expect a big eye roll! And expect to show me that product documentation.
