We're now making an amphibious robot that will have the same swimming and walking properties, but will be a bit more sturdy, here clearly there's a big interest of having a robot that can crawl, go through small spaces, can swim a bit. And if you have a collapsed building; you think there are survivors, you will not send a dog because maybe the building is too dangerous. It may be very interesting to have an amphibious robot that you remote control; see if there are survivors and decide then if it's worth sending a team or not.
