Briefings

Caltech researchers developed a robotic truss builder designed for the DARPA NOM4D program that successfully assembled a space structure without astronauts. The autonomous manipulator picked up struts and joints from nearby dispensers to build identical perimeter truss bays. This marks the first autonomous construction of a space structure in orbit.

Key points

• Caltech researchers designed and built a robotic truss builder for the DARPA NOM4D program.
• The autonomous manipulator assembled a space structure using struts and joints from nearby dispensers.

Context

The project is part of DARPA's Novel Orbital and Moon Manufacturing, Materials, and Mass-efficient Design (NOM4D) program. This achievement represents the first time a robotic system has built a structure in space without human assistance.

Limitations

Evidence covers only the successful assembly of a single perimeter truss bay. No data on total structure size, construction duration, or number of bays built is provided. The source does not specify the exact location of the dispensers or the specific orbital altitude.
