Autonomous mobile robots are one of the new and innovative ways to improve operation in industries such as: warehouses. They are known for their popular operational improvement, safety, and speed. An important feature of an AMR is the capability to charge autonomously with little to no human intervention.It should be able to determine when it has reached the threshold value of the battery capacity and navigate to the charging station, connect, recharge, disconnect and resume its tasks. This thesis examines the energy distribution on multi-robot warehouse systems. We experimented several cases and the results have been tracked for the number of tasks completed, the waiting time, and dead robots. The best possible solution is when the robots are compatible to the existing charging stations, in this case there will be minimal or no dead robots. We investigated the performance of robots when they collaborate and share power with one another.
