Abstract: To address the technical challenges commonly observed in conventional elevator systems—namely, reliance on physical contact for human-machine interaction, high retrofitting costs, and poor adaptability to emergent public health requirements—this study proposes a novel non-contact remote elevator control system based on Internet of Things （IoT） technology. The proposed system features a non-invasive deployment strategy and employs a servo motor to accurately emulate manual button presses, thereby enabling intelligent control of legacy elevator systems without requiring any hardware modifications. The research primarily focuses on the mechanical design of the device, integrated development of hardware-software control modules, and the robustness of wireless communication protocols. Comprehensive evaluations, including functional testing, environmental adaptability analysis, and validation in representative operational scenarios, demonstrate that the system offers high compatibility, responsiveness, and operational reliability. This IoT-enabled solution effectively satisfies the growing demand for contactless elevator operation, intelligent retrofitting, and autonomous robotic mobility, providing a promising reference for the rapid implementation of smart building infrastructures and automated management of shared public spaces.
