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 trajectory generating method includes a first generating process of generating a plurality of trajectories between a start teaching point and a target teaching point, an evaluation process of evaluating a motion of the robot arm on each trajectory to calculate an evaluation value of each trajectory, a selection process of selecting one of the plurality of trajectories based on calculated evaluation values, and an update process of updating the trajectory by repeating the processes of generating a plurality of new trajectories by changing a selected trajectory in the selection process, of calculating an evaluation value of a motion of the robot arm on each changed trajectory and of selecting a trajectory based on calculated evaluation values.

A hyperdexterous surgical system can include one or more surgical arms coupleable to a fixture and configured to support one or more surgical tools. The system can include an electronic control system configured to communicate electronically with the one or more surgical tools. The control system can electronically control the operation of the one or more surgical tools. The system can include one or more portable handheld controllers actuatable by a surgeon to communicate one or more control signals to the one or more surgical tools via the electronic control system to operate the one or more surgical tools. The one or more portable handheld controllers can provide said one or more control signals from a plurality of locations of an operating arena, allowing a surgeon to be mobile during a surgical procedure and to remotely operate the one or more surgical tools from different locations of the operating arena.

A robotic surgical system includes a controller configured or programmed to perform an arm interference avoidance control to move a second manipulator arm relative to a first manipulator arm such that a reference line moves along an outer edge of an approach prohibited range of a first manipulator arm when a second manipulator arm approaches within the approach prohibited range.
