Abstract
A self-propelled object is a type of functional inanimate system used in the development of novel micro-robot designs. Many studies on the application of selfpropelled objects as drug delivery systems, cleaning systems for polluted water cleansing, and target DNA sorting systems have been reported. In order to realize additional functional systems, environmental responsivity is a desired feature of self-propelled objects. In this mini-review, we focus on self-propelled objects’ responses to environments with different chemical and light conditions, and classify the examined systems based on their sensitivity to various conditions.
Keywords: Inanimate devices, micro-robot designs, responsivity, self-organization, self-propelled object, spontaneous motion.
