  • Patent number: 11338576
    Abstract: A mobile printing robot includes a windbreak to reduce wind-induced deflection of ink droplets emitted from a printhead of the mobile printing robot. The printhead may have a comparatively large throw height to aid in permitting obstacles, such as particles from safely passing under the printhead without damaging the printhead or cause the printhead to become stuck. The windbreak may be implemented using resiliently compliant sections that block the wind but accommodate the passage of particles or other obstacles.
