Abstract

Four-dimensional (4D) printing has been rapidly emerging in robotic manufacturing. In order to tackle delicate jobs, in various adaptive environments, such as sorting food, manipulating human organs and tissues, and locomotion in inaccessible terrain, stiff actuators, sensors, and even central controller units are often replaced with soft and flexible materials in traditional robots. Additive manufacturing of robots gained researchers' attention in recent years. Soft polymer materials, like poly-dimethyl siloxane (PDMS), have been developed and additive manufacturing has made it easier to practice them. Recently, a broader range of smart robotic materials with the capability of response and adaptation to external stimuli have been introduced in additive manufacturing. Soft robotics may now be actuated by external stimuli of electric, magnetic, chemical, thermal, or photonic origin thanks to the improved functionalities of smart materials that induce programmable modulations in size, shape, and stiffness. In operating soft robots, a magnetic field provides unique benefits, such as penetrating a variety of materials, remote commanding, and fast response time, with applications in an enclosed location, such as surgical catheters or untethered drug-delivering robots working in the human body. This chapter presents and categorizes numerous state-of-the-art electromagnetic robotics materials made using 4D printing. The operating principles, manufacturing processes, and their associated benefits and disadvantages, as well as future potential, are outlined.
