Embodiments implement a minispace concept to dynamically manage layout of a robotics warehouse system. The warehouse space is divided into a plurality of equally sized minispaces, each corresponding to a standard rack footprint. Each minispace is identified by tagging with a unit location ID and attribute(s) such as coordinates. Minispaces may be referenced in a task planning process flow that initially comprises determining stock and rack, followed by determining a relevant workstation. The task is then assigned to an appropriate robot, and a travel route is planned (e.g., shortest path in minispace layout). Robot actions within the route are then planned and executed by the warehouse management system according to the minispace layout. Minispaces allow a robot to identify each minispace by the tagging, and to plan the next movement accordingly. The use of minispaces may facilitate collision avoidance by grouping actions together and allowing performance of minispace locking/checking procedures.
