ABSTRACT Light‐driven micro/nanorobots (LMNRs) are promising tools for applications in environmental remediation and biomedical intervention. However, most LMNRs operate under single‐wavelength illumination, limiting their actuation programmability and adaptability. Here, we report a decoupled dual‐wavelength light‐driven microrobot system based on BiVO 4 microparticles coated with an organic semiconductor (OSC), forming BiVO 4 –OSC microrobots (BOSMs). This hybrid design enables spectrally decoupled actuation under blue (480 nm) and near‐infrared (808 nm) light, allowing independent control over distinct motion modes such as acceleration and deceleration. Moreover, the dual‐wavelength acceleration enhances microplastic removal efficiency in aqueous environments, demonstrating the system's potential in environmental cleanup. This work introduces a new approach to the development of decoupled‐wavelength light‐driven microrobots with adjustable mobility, which could be further expanded for a wide range of applications, including efficient environmental remediation.
