AI Technical Summary
Existing modular space trusses have low volume utilization during transportation, strong connection directionality, and are difficult to freely combine to form arbitrary two-dimensional topologies. Furthermore, mechanical grippers have problems with space constraints and difficulty in maintaining posture.
It adopts a bistable folding truss structure, including an upper frame, a lower frame, side columns and elastic tensioning members. It can be folded and twisted through hinged connectors and limiting structures. The elastic tensioning members form an energy barrier and self-holding capability, and the magnetic components and splicing interfaces achieve stable connection.
It achieves volume compression and automated deployment during transportation, possesses elastic potential energy and end-state self-holding capability, reduces the continuous load requirements of robot assembly, and improves the stability and flexibility of module combination.
