Design and Implementation of a Concrete Carbon-Sequestration Curing Robot Based on an Elephant-Trunk-Inspired Bionic Arm

Abstract

Concrete curing is vital for building strength and durability. Traditional methods, however, face issues like unstable quality, high carbon footprints, and resource waste. This paper introduces a robot using an elephant-trunk-inspired arm for carbon-sequestering concrete curing. The system merges biomechanics with electromechanical control, employing a cable-driven soft continuum structure with a "cable traction + flexible backbone" setup. This allows for agile, multi-directional motion and precise spraying across various mediums. Additionally, a multidimensional fuzzy control model enables collaborative curing and carbon sequestration. By tracking real-time environmental data like temperature and humidity, it optimizes spraying to boost concrete hydration and CO₂ absorption. Experimental data reveals that the newly designed robot markedly enhances curing uniformity. When pitted against conventional curing techniques, it slashes water use by about 30% and electricity consumption by 40%. Moreover, it boosts CO₂ sequestration per square meter of concrete by 25%, cutting costs and environmental harm, and aiding green construction.
