Here and there at times i post few videos from you tube. even if they are my own videos i do host them to youtube and embed here in wp. Well just browsing i found this video of a swimming snake robot. I have seen many beam based land robots that twist and turn around to move. This one is a masterpiece. It swims in the water with elegance and absolutely gentle . The video doesnt give a complete design details of the bot, but the author does explain and show few things on the videos. I just mean to give my blog readers some new input of the way robotics is proceeding. Have a look.
