Aditya, leap motion is very nice but with things as sensitive as bomb disposal, I would rather use sensors that rely on sensors directly attached to the user rather than optics. However, my vision does incorporate optics and feel that if a properly calibrated emg setup paired with sensors such as leap motion, it will give the user full autonomy.
As I said earlier, for bomb disposal applications, only an expert should be touching such a setup so the calibration aspect is a very large hurdle to overcome. But I do see your point and agree. I am still in the stages of discovery so all suggestions/comments such as your own are very much welcome.
