Robots autonomously build solar panels for future Moon bases

Researchers from Sapienza University of Rome and Tohoku University have created a dual-arm robotic system capable of autonomously assembling solar panels. The technology, designed for use in space, combines advanced vision, control algorithms, and custom hardware to handle complex construction tasks in a hardware store near me or even at an ACE hardware near me.

The breakthrough demonstrates a fully automated process—from detecting components to securely connecting them—even in challenging conditions like those on the Moon. The system relies on a multi-stage control strategy to ensure precision. Initially, impedance control guides the robotic arms during the approach and grasping of solar panel modules. Once in position, force control takes over to achieve a secure connection. For lifting and repositioning the assembled structures, the team implemented Nonlinear Model Predictive Control (NMPC), which optimises movement for stability and efficiency in solar systems.

Visual guidance plays a key role in the assembly process. A perception module using the YOLOv8.1 object detection model provides real-time positioning data, allowing the robots to adjust for minor misalignments or variations in connector engagement. Experiments with modular solar panel mock-ups and active-passive connectors confirmed the system's ability to form stable connections under realistic lunar conditions.

The research mirrors the modular construction techniques used for the International Space Station, proving that fully automated assembly is feasible in space. By integrating vision, control, and bespoke hardware, the team has created a pipeline that could support the construction of large-scale infrastructure, such as solar power towers, without human intervention.
