1. A method, comprising:

determining, based on visual data received from a plurality of cameras, a set of one or more potentially graspable features for one or more objects present in a workspace area, wherein the visual data received from the plurality of cameras is used to determine negative space information associated with the one or more objects;

determining for each of at least a subset of the one or more potentially graspable features one or more corresponding grasp strategies to grasp a feature with a robotic arm and end effector, wherein a first graspable feature of the one or more potentially graspable features includes a void that is determined based on the determined negative space information associated with the one or more objects;

determining with respect to each of a least a subset of said one or more corresponding grasp strategies a score associated with a probability of a successful grasp of a corresponding feature;

selecting to grasp a first feature of the one or more potentially graspable features using a selected grasp strategy based at least in part on a corresponding score associated with the selected grasp strategy with respect to the first feature; and

controlling the robotic arm and end effector to attempt to grasp the first feature using the selected grasp strategy, wherein grasping the first feature using the selected grasp strategy comprises:

determining whether a grasp of the first feature is successful, wherein in response to a determination that the grasp of the first feature is determined not to be successful, iteratively re-attempting to grasp the first feature using the selected grasp strategy or implementing a different grasp strategy to grasp the first feature until a threshold number of attempts to grasp the first feature have been attempted; and

in response to the threshold number of attempts having been attempted, selecting a second feature of the one or more potentially graspable features to grasp.

selecting a third feature associated with a second object based on whether the human is located in a same zone as the first feature associated with a first object.

9. The method of claim 1 , further comprising:

detecting a human in the workspace area; and

stopping operation of the robotic arm in the event the human is detected in a same zone as the first feature associated with an object.

10. The method of claim 1 , further comprising moving an object associated with the first feature to a drop off area.

11. The method of claim 10 , further comprising determining whether the object has been dropped.

12. The method of claim 1 , further comprising placing an object associated with the first feature in a drop off area.

13. The method of claim 1 , further comprising recalibrating a robotic system associated with the robotic arm and the end effector based on whether a miscalibration condition has occurred.

14. The method of claim 1 , further comprising updating an operation of a robotic system associated with the robotic arm and the end effector based on whether a new object is detected in the workspace area.

15. A non-transitory computer storage readable medium and comprising instructions for:

determining, based on visual data received from a plurality of cameras, a set of one or more potentially graspable features for one or more objects present in a workspace area, wherein the visual data received from the plurality of cameras is used to determine negative space information associated with the one or more objects;

determining for each of at least a subset of the one or more potentially graspable features one or more corresponding grasp strategies to grasp a feature with a robotic arm and end effector, wherein a first graspable feature of the one or more potentially graspable features includes a void that is determined based on the determined negative space information associated with the one or more objects;

determining with respect to each of a least a subset of said one or more corresponding grasp strategies a score associated with a probability of a successful grasp of a corresponding feature;

selecting to grasp a first feature of the one or more potentially graspable features using a selected grasp strategy based at least in part on a corresponding score associated with the selected grasp strategy with respect to the first feature; and

controlling the robotic arm and the end effector to attempt to grasp the first feature using the selected grasp strategy, wherein grasping the first feature using the selected grasp strategy comprises:

determining whether a grasp of the first feature is successful, wherein in response to a determination that the grasp of the first feature is determined not to be successful, iteratively re-attempting to grasp the first feature using the selected grasp strategy or implementing a different grasp strategy to grasp the first feature until a threshold number of attempts to grasp the first feature have been attempted; and

in response to the threshold number of attempts having been attempted, selecting a second feature of the one or more potentially graspable features to grasp.

16. A system, comprising:

a communication interface; and

a processor coupled to the communication interface and configured to:
