A composite is formed by the combination of two or more constituent materials differing in their physical and chemical properties. When the final product is produced, it is different from the individual components. Recently, many researchers have also begun to actively include sensing, actuation, computation, and communication into composites [93], which are also called robotic materials. Some typical examples of composite materials are wood, clad metals, fiberglass, reinforced plastics, cemented carbides, and so on. Among these, fiberglass, in which glass fibers are embedded within a polymeric material, is mostly used in many applications. In this composite, the fiberglass acquires strength and flexibility from the glass and from the polymer. Many efforts have been made by researchers to develop new composite materials with desired properties. Thus, recent developments in the material field have involved composite materials. Also, nanocomposites are a rapidly expanding field for the development of science and advanced technology due to the availability of new advanced materials with unique electrical and optical properties. The class of nanocomposites includes organic or inorganic new hybrid materials, which is a fast-growing field of research. Continuous efforts have been made to improve the properties of nanocomposite and to control their morphology and interfacial characteristics. Polymer-based nanocomposites have many important applications in electronics as charge storage capacitors, integrated circuits (ICs), and electrolytes for solid-state batteries.

Many teams identified compliance as a critical element of their technical strategy to make up for perception uncertainty, which is in contrast to rigging all parts as precisely and accurate as possible, such as in FA.COM and Robotic System Integrators' approaches, which could be labeled as ‘conventional robotic workcells’. Specifically Robotic Materials, JAKS, O2AS, BerlinAUTs, and CMIT each identify using some combination of vision, feedback control, and compliance to create reusable software components that are robust to uncertainty in part location. SDU Robotics chose a middle ground, by relying both on rigging and feedback control and introduced flexibility by 3D printing appropriate fingers and tools, facilitated by their digital-twin programming approach. None of the teams relied exclusively on robotic grippers, but either used tool changers or used their grippers to pick up additional tools such as screwdrivers (Robotic Materials, O2AS, e.g.) or suction cups (O2AS).
