Robotic manipulators can inspect satellites, move equipment, assemble structures, and support future in-space servicing.

Background and core principles

A space arm must manage inertia and contact forces while its base may itself move. Cameras, force sensors, joint encoders, and carefully planned trajectories help avoid collisions with fragile antennas, thermal blankets, and solar arrays.

Engineering, evidence, and constraints

Tasks such as refuelling or capturing an unprepared satellite are difficult because target geometry, rotation, and interface standards vary. Servicing also raises questions about ownership, authorisation, safety, and the consequences of a failed manoeuvre.

Research outlook

Successful systems need repeatable demonstrations, robust fault recovery, and standard interfaces wherever possible. In-space servicing could extend asset life, but feasibility depends on mission economics, target design, and the reliability of each operation.
