This “multi-gait soft robot” may be moved by sequentially inflating its various air pockets. Kinda creepy-cool the way it undulates under an obstacle! [Wired Science via b_b]

    That’s so cool! Now how do you make it? Where are the instructions?

      here’s how they made this one( ) you can also do look up soft robots on youtude for some other info.

      The basic idea is you pump air or some other working fluid into a silicone rubber bladder (ecoflec is the name of the silicone they use which can be found in a sample size large enough one or more this size of for $30 us online) if one side of the bladder is thinner that side with expand quicker bending the bladder towards the thicker side.
