“A Soft Robotic Tongue–Mechatronic Design and Surface Reconstruction” (Lu, Xu, Li) presents a actuated device mimicking a tongue. I was interested in this article because of the range of complex surface deformations the authors were able to accomplish with just six pressure-controlled air chambers.
