  • Patent number: 12097620
    Abstract: Provided are methods and apparatus for environment-adaptive robotic disinfecting. In an example, provided is a method that can include (i) creating, from digital images, a map of a structure; (ii) identifying a location of a robot in the structure; (iii) segmenting, using a machine learning-based classifying algorithm trained based on object affordance information, the digital images to identify potentially contaminated surfaces within the structure; (iv) creating a map of potentially contaminated surfaces within the structure; (v) calculating a trajectory of movement of the robot to move the robot to a location of a potentially contaminated surface in the potentially contaminated surfaces; and (vi) moving the robot along the trajectory of movement to position a directional decontaminant source adjacent to the potentially contaminated surface. Other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 6456901
    Abstract: A hybrid control system is provided for controlling the movement of a robot. The hybrid control system includes a singularity detector; a task level controller that receives a motion plan and determines a first set of control commands which are defined in a task space; and a joint level controller that receives the motion plan and determines a second set of control commands which are defined in a joint space. The singularity detector monitors the movement of the robot and detects robot movement in a region about a singularity configuration. When robot movement occurs outside of this region, the task level controller is operable to issue the first set of control commands to the robot. When the robot movement occurs inside of this region, the joint level controller is operable to issue the second set of control commands to the robot. In this way, the hybrid control system ensures feasible robot motion in the neighborhood of and at kinematic singularity configuration.
