Strategies for Continuous Responsive Motion in a Constant Environment.

Continuous responsive motion gains significant attention due to its widespread applications in autonomous braking systems, low-power generation, human-computer interaction, and other fields. Continuous responsive motion in a constant environment is particularly important because it enables self-sustained actuation in unmanned settings. In this review, four strategies are summarized for continuous responsive motion in a constant environment and elaborate on the mechanisms, including the Belousov-Zhabotinsky reaction strategy, the self-shadowing effect strategy, the gradient stimulus field strategy, and the complex device-based strategy. This study first provides a brief overview of the development history of continuous responsive motion systems in a constant environment. Then, the basic principles, advantages, disadvantages, and application scopes of the four strategies are illustrated. Afterward, the applications of these continuous responsive motion systems are summarized. Finally, the current challenges and future perspectives are presented for the field of continuous responsive motion in a constant environment, offering inspiration for the development of new continuous responsive motion systems.
