Soft robotic systems are inherently safe for human interaction and are able to perform
useful tasks such as grasping or locomotion. Reliably producing the complex, monolithic,
3D structures necessary in these systems remains a challenge due to limitations
in the available manufacturing methods. Historically, these systems have been made
with molding, casting, stamping, and other techniques. Unfortunately, these methods
are largely limited to 2D and thus inhibit the robots’ potential complexity.
