Starting from my previous entry for Exercise One, Soft Lego Blocks (J. Lee, J. Eom, W. Choi and K. Cho, “Soft LEGO: Bottom-Up Design Platform for Soft Robotics,” 2018 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), Madrid, 2018, pp. 7513-7520, doi: 10.1109/IROS.2018.8593546.), I looked at their referenced work for the project. From there I found a project which utilized inflatable multimaterial inflatable soft blocks (J. Y. Lee, W. B. Kim, W. Y. Choi and K. J. Cho, “Soft Robotic Blocks: Introducing SoBL a Fast-Build Modularized Design Block”, IEEE Robot. Autom. Mag., vol. 23, no. 3, pp. 30-41, Sep. 2016.) which also used a bottom-up approach, in this case to allow for the replacement and repair of worn down parts. From that paper I looked at one of the referenced papers (Y. L. Park, J. Santos, K. G. Galloway, E. C. Goldfield and R. J. Wood, “A soft wearable robotic device for active knee motions using flat pneumatic artificial muscles”, pp. 4805-4810, 2014.) which worked on a soft wearable robotic device made from two-dimensional pneumatic artificial muscles to aid knee extension/flexion. This device is designed to aid in the rehabilitation of injured nervous systems.
