Source paper: An untethered jumping soft robot
M. T. Tolley et al., “An untethered jumping soft robot,” 2014 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2014, pp. 561-566, doi: 10.1109/IROS.2014.6942615.
The paper describes the development and fabrication of a jumping soft robot, which constitutes a breakthrough since locomoting soft robots typically walk or crawl slowly relative to their rigid counterparts.
Root paper: The challenges ahead for bio-inspired ‘soft’ robotics

Along the way, I found another paper that I found very interesting – “Aiming and vaulting: Spider inspired leaping for jumping robots”
H. Faraji, R. Tachella and R. L. Hatton, “Aiming and vaulting: Spider inspired leaping for jumping robots,” 2016 IEEE International Conference on Robotics and Automation (ICRA), 2016, pp. 2082-2087, doi: 10.1109/ICRA.2016.7487357.
which cited the paper I started with but not the root paper.
