This picture is of a project called Bend Bots created by Ann Marie Cernoch. These figures are made using Flexinol wire actuated by an electric current passing through them. The author notes some important challenges with using the Flexinol wire in regards to attachment of Flexinol to fishing wire. Flexinol is difficult to solder due to low heat tolerance and the author devises a work around by gluing the Flexinol onto a larger wire and then soldering. A link describing the Bend Bots is given: http://www.evl.uic.edu/core.php?mod=4&type=1&indi=385.
