  Light-actuated motors, vehicles, and even space sails have drawn tremendous
attention for basic science and applications in space, biomedical, and sensing
domains. Optical bound states in the continuum (BIC) are topological
singularities of the scattering matrix, known for their unique light trapping
capability and enhanced light-matter interaction. We show that BIC modes enable
the generation of enhanced and tunable optical forces and torques. A sharp and
controllable lineshape is observed in forces and torques spectra when
approaching high-Q resonance BIC modes. Wavelength and polarization tunability
are presented as an effective method to control the forces on BIC enclosed
structures. Finally Finite-size simulations are performed to evaluate the
practical application for a BIC assisted metavehicle.
