Locomoting soft robots typically walk or crawl slowly relative to their rigid counterparts. In order to execute agile behaviors such as jumping, rapid actuation modes are required. Here we present an untethered soft-bodied robot that uses a combination of pneumatic and explosive actuators to execute directional jumping maneuvers. This robot can autonomously jump up to 0.6 meters laterally with an...
Combustion causes a soft robot to jump: Rapid actuation of a soft robot (composed of silicone elastomers) was achieved using high‐temperature chemical reactions. Computer‐controlled electrical sparks triggered the combustion of premixed CH4 and O2 gases inside the robot, which pressurized the pneumatic channels of the robot and caused it to jump (see figure). The heat from the explosions dissipated...
