It seems there are a few problems. For example, the consumption of mana. It seems that with Zanoba's mana capacity, he'll be out of it after 2 or 3 hours of use. Among the other problems are that the fingers are too fat and unrefined, for example, or that the sense of touch is a little dull. If those types of problems can be fixed, I'm sure that it would be the completion of something amazing. However, in the end, this is just a byproduct of research.
Our goal is to create a moving doll. This glove would sell well, it'd be convenient to have, and one day, we'd also be able to sell it for real, but taking too long on this project probably wouldn't be good.
