[Notice] Beginner's Guide to the Hollows: How to Modify Your Bangboo
We all know the Association issues Investigators with special Bangboo for use in the Hollows that are designed to help them better complete their Hollow exploration tasks. Hollow Raiders, on the other hand, don't have this luxury, and so must modify their own little helpers. Fortunately, it's not difficult to modify a Bangboo for Hollow exploration, and these little robots are inherently very powerful and expandable.
The first step in modification should, of course, be to install a Carrot recognition program — which is not installed by default on home Bangboo. This provides the Bangboo with the critical function of providing safe paths through Hollows. 
According to incomplete statistics, 73% of Inter-Knot users tend to buy the construction model Bangboo as a basis for modification. Compared to the home model, the construction model does not have the customizable voice feature, but it has 2 more expansion slots for individual components and 1 more built-in backup power supply. This allows modifiers to add 2 to 3 wide-area acquisition modules or material sensors.
There is, of course, an upper limit to the load a Bangboo can take on. Cramming components recklessly might lead to the Bangboo breaking down prematurely under the strain. If you're uncertain about the best way to modify your Bangboo, you can seek advice and the experience of peers in the industry or opt for specialized modification shops to do the work on your behalf.

If you have a limited budget, Bangboo used for transport work are a good idea. They're easy to get and not too difficult to modify. The main bonus being they can carry a lot of items in the Hollows.

I've gone through a few Bangboo, but they've all made these "ehn ehn" sounds. Is it an issue with my modifications?
Watermelon Pomegranate Juice
It's got nothing to do with your mods. Even Investigator Bangboo make the same sounds. I hear it's the Bangboo's own encrypted language set. The way it sounds is just the designer's own bad taste...
