RAD sampler design. RAD sampler design. (A) One arm of the RAD sampler with revolute joints shown as dotted lines. A fold is initiated by rotating the central fold link with respect to the central assembly link. (B) Axisymmetric dodecahedron net. Each arm is made by connecting a folding unit with its rotated chiral counterpart. (C) Folding sequence when encapsulating a marine organism. Zhi Ern Teoh et al. Sci.
