However, planning and executing those tasks taking full advantage of the available resources is a completely different question. This can be challenging when dealing with real-world hardware constraints, especially so when there are multiple instruments with different capacities and throughputs . Here we demonstrate a 2-step method to address resource utilization for our autonomous platform for metalorganic framework synthesis. First, we use constraint programming to find optimal schedules. This finds schedules that minimizes the total time while still satisfying the limitations and capacities of the hardware . Secondly, we use a system of status dependencies for each task, which allows for the robust execution of the optimal schedules.  \n1 Introduction  \nAutonomous systems are becoming ever more popular for experiments in materials and other physical sciences. 1,2 There is a recognized need to orchestrate the actions within an autonomous experimental platform.3 There have been a few developments of autonomous laboratory orchestration to date. These include ARES OS 4,5 , HELAO-async 6 , NIMS-OS 7 , ChemOS 2 .08,9, EOS 10 , Bluesky+ROS211, MULTITASK 12. Many of these efforts have been focused on facilitating the deployment of autonomous laboratory components: networking computational resources, instrument communication, implementing server-client models for the instrument AI actions, facilitating different architectures for how AI agents can interact between themselves and with the instruments. In this paper we address a slightly different problem, namely, given a set of requested experiments from the AI agents, how do we make optimal use of the available instrumental resources?  \nOne of the issues with attempting to optimize the use and schedule of resources on an autonomous platform, is that we, asthe operators and programmers, do not know a priori what tasks will be asked of platform to execute. In an autonomous system, there is an AI agent (or several 12 ) that is attempting to answer some question at hand (e.g. find some optimal property, answer some scientific question) . These AI agent(s), through their acquisition functions, are generating list of requested new data points. The orchestrator of the platform must make decisions about how  \naMaterial Measurement Laboratory, National Institute of Standards and Technology, Gaithersburg, MD, USA  \nbORCID: 0000-0002-3767-926X, [austin.mcdannald@nist.gov](austin.mcdannald@nist.gov)[ ](austin.mcdannald@nist.gov)[c](cORCID: 0009-0008-0012-1714)[ORCID: 0009-0008-0012-1714](cORCID: 0009-0008-0012-1714)  \n[d](dORCID: 0000-0002-6552-2972)[ORCID: 0000-0002-6552-2972](dORCID: 0000-0002-6552-2972)  \nthose requests are executed: what actions are performed by what resource of the platform and when. There are some cases when this orchestration might be trivial. For example, if there is only enough capacity to perform one job a time, then all the jobs must be executed serially. Also if there is enough capacity to perform all jobs in parallel, then the orchestration is also trivial. Lastly, if the platform can execute the jobs at the same speed that the AI sends requests, then there will only be 1 job in the list, which is again trivial. Complications can arise, however, when there is only capacity for some jobs in parallel - especially if those jobs can vary widely in execution time. Further complications can be when there are interrelated dependencies - e.g. parallel capacity, but only if certain conditions are met, or the execution of atask in one job depends on a task from another job. In general simply finding optimal schedules for a set of jobs is NP-hard. 13,14 Furthermore, orchestrating the execution of the schedules comes with
