    • Example systems and methods may allow for parallel operation of robotic devices within a workcell, such as industrial robots controlled to manufacture an output product. One example method includes receiving ordered sequences of operations for a plurality of corresponding robotic devices, determining time-based sequences of operations for each of the robotic devices, where a time-based sequence of operations indicates positions within the workcell at corresponding timesteps of a global timeline, determining one or more potential collisions involving the robotic devices that would result from parallel execution of the time-based sequences of operations within the workcell, modifying the time-based sequences of operations in order to prevent the one or more potential collisions, and providing instructions for parallel execution of the modified time-based sequences of operations at timesteps of the global timeline by the robotic devices within the workcell.

    • A robot is provided with a motion control unit. The motion control unit of the robot comprises
      - a distance computing module calculating the two closest points of different segments of the robot connected to each other via at least one joint, or a segment of the robot and another object, and outputting
      - a whole body control module,
      - a collision avoidance module supplied with an output signal from the distance computing module,
      - a blending control unit for combining the weighted output control signals of the whole body control module and the collision avoidance control module,

      wherein the weight of the whole body control output signal is the higher the lower a calculated collision risk, and
      wherein the weight of the collision avoidance control output signal is the higher the higher the calculated collision risk.
      The collision avoidance module is designed for
      - calculating the two closest points of different segments of the robot connected to each other via at least one joint, or a segment of the robot and another object, and
      - controlling a collision avoidance action only in the dimension along the connection line between the closest points.
