Paper 1: Thermally Tunable, Self-Healing Composites for Soft Robotic Applications (citation 40)

Polyurethane foams and 3D-printed lattice structures were covered in wax and tested at various temperatures. The results indicated that wax-coated structures have the potential to act as a much more controllable medium for robotics, allowing for controlled changes and repairs to be made to the structure’s stiffness modulus through temperature change.

Paper 2: Puffy, a friendly inflatable social robot (S21 R75)

This paper (and supplementary video) discusses the purpose and features of a Baymax-esque soft robot designed to improve children’s learning environments. The video demonstrates a classroom application of the technology using a conceptual prototype, however neither it nor the article go into technical depth. That being said, it is made clear that the multi-sense interactivity and target aura of Puffy is largely possible due to it being a soft robot.

Paper 3: Electroactive textile actuators for wearable and soft robots (IEEE)

Dielectric elastomer actuators (DEAs) are thin, multilayered membranes that physically deform as a result of a voltage being applied. This paper tested the relative change in top surface area as a result of small voltages (9kV and 6kV) being applied to multiple DEA configurations. This technology can harness this deformation to create specific movements and ultimately achieve actuation from a voltage supply.
