ICYMI: Robosurgeon, wigglebot and a very cute penguin

Today on In Case You Missed It: A robot from the Ben-Gurion University of the Negev produces a wave-like motion that can propel itself across a floor or through water, only with one motor. Also a robotic surgeon called Flex can snake its way down throats or other orifices and perform surgeries in a less-invasive way than traditional means.

But you should probably take in Purps the penguin and her 3D-printed boot, and also the robotic massager we all wish we had. As always, please share any interesting tech or science videos you find by using the #ICYMI hashtag on Twitter for @mskerryd.
