In-Space Robotic Assembly of Large Shape-Precise Structures - College of Engineering - Purdue University

Project Description

Delivering structures with a large, expanded area to space such as communications antennas is critical for space missions and exploration. Deployable structures have been the prevailing approach to that end, but scaling up the size while maintaining the shape precision is extremely challenging. Direct in-space assembly of structures from building-block elements presents a promising solution to lower logistical footprint, reduce design complexity, and enhance shape precision of mechanical structures on orbits and surfaces.

This project focuses on making advances on two fronts in robotic assembly of large structures in space. First, we will study thermoplastic composites with embedded nanomaterials that can be welded and unwelded repeatedly with low energy expenditure. Mastering this basic welding and unwelding operation will enable constructing and repurposing structures based on changing needs. The thermal process control, strut and joint design, structural strength will be investigated via computationally and experimentally in the relevant space environment. Second, we will develop robotic systems for assembling and disassembling large truss structures made of thermoplastic composite elements. We are broadly interested in systems with high-precision manipulation and autonomous navigation. Implementation and testing of robotic systems under compensated gravity conditions will be a major component in this effort. Candidates with background in either area are highly encouraged to apply.
