An example method for allowing a robot to assist with a task, the task being carried out in an environment including one or more non-human objects each having associated object locations, comprises detecting one or more changes in object locations within the environment, predicting a task requirement (such as a future object location change, or task goal) by comparing the change in the object location with stored data, the stored data including object location changes associated with previously observed tasks; and providing robotic assistance to achieve the task requirement. Example apparatus are also disclosed.
