- Abstract: Developing practical quantum technologies will require the exquisite
manipulation of fragile systems in a robust and repeatable way. As quantum
technologies move towards real world applications, from biological sensing to
communication in space, increasing experimental complexity introduces
constraints that can be alleviated by the introduction of new technologies.
Robotics has shown tremendous progress in realising increasingly smart,
autonomous and highly dexterous machines. Here, we demonstrate that a robotic
arm equipped with a magnet can sensitise an NV centre quantum magnetometer in
challenging conditions unachievable with standard techniques. We generate
vector magnetic field with $1^\circ$ angular and 0.1 mT amplitude accuracy and
determine the orientation of a single stochastically-aligned spin-based sensor
in a constrained physical environment. Our work opens up the prospect of
integrating robotics across many quantum degrees of freedom in constrained
settings, allowing for increased prototyping speed, control, and robustness in
quantum technology applications.
