Precision mechanical coupling between autonomous fuel supply tenders and combat UGVs demands microsecond-synchronized relative velocity matching.
Cooperative infrared fiducial markers and dual-wavelength optical rangefinders compute 6-DoF relative poses at 200 Hz with sub-millimeter precision.
Upon contact, the receiving UGV transitions from position control to an active admittance control regime, dissipating docking kinetic energy safely without mechanical binding.
