Brief
Sarah Downs, now a Ph.D. student at Texas A&M, created a force-based insertion algorithm that lets a robotic arm assemble satellite antennas in zero gravity without relying on cameras. Her work, done with NASA and the U.S. Air Force during her master’s, addresses peg‑in‑hole insertion and compensates for reaction torques in space.
Why It Matters
The algorithm improves robotic reliability for in‑space assembly where cameras can fail and motion can destabilize satellites.
