From enhanced efficiency and data-driven insights to advanced navigation and predictive maintenance, the integration of AI promises to redefine the capabilities of AMRs and reshape the future of these industries.

Why Traditional AMR
Task Scheduling Falls Short

Life Science and Healthcare facilities have seen a steady rise in the incorporation of automated mobile robots (AMRs). Promising to free staff from repetitive material transport, improve workflow logistics, and increase output speed, AMRs show immense potential. However, the benefits of such robotic solutions is limited without an effective task scheduling and assignment method in place. Manual and rule-based scheduling struggle to keep pace with the complex and variable demands of these settings.

Manual Task Scheduling Limitations

Manual task scheduling involves human operators directly assigning tasks to AMR robots, based on their own understanding of current priorities. This method is common in smaller facilities with lower throughput and predictable tasks. However, as complexity and scale increase, it unequivocally leads to inefficient scheduling of resources.

Limitations of Manual Task Assignment include:

  • Time-Consuming and Error-Prone: Manually task assignment for multiple AMRs is tedious, leaving room for human error in route optimization, and priority setting.
  • Difficulty Adapting to Real-Time Changes: As priorities shift, manual schedules require frequent adjustments, consuming valuable staff time and causing bottlenecks and delays in critical operations.
  • Inefficient Routing: Human schedulers may not always identify the most efficient routes or task assignments for AMRs, leading to delays in time-sensitive task completion and increased operational costs.

Rule-Based Task Assignment Limitations

Rule-based task assignment represents a step up from manual methods, employing predefined rules and conditions to automate mobile robot job sequencing and scheduling. For example, a rule might dictate that automated robots prioritize STAT sample deliveries over routine material transport, which may be sufficient for more predictable workflows.

However, Rule-Based Task Assignment fails to adapt to unexpected situations, with limitations including:

  • Inflexibility: Predefined rules cannot account for every possible scenario, leading to suboptimal decisions when AMR automation encounters unexpected events, like equipment malfunction or urgent requests, occur or conditions change.
  • Frequent Manual Intervention: Rule-based systems are rigid and cannot dynamically accommodate exceptions without manual adjustment by human operators. This places a burden on staff and introduces the risk of human error back into the task scheduling process.
  • Limited Ability to Improve: Unlike AI scheduling systems, rule-based schedulers don’t learn from past data or adapt decision-making over time, hindering continuous improvement of robotic solutions.

Other Traditional Scheduling Limitations

  • Queue-Based Scheduling: Queuing up tasks for AMRs to take on in the order they are received. While simple and straightforward, this approach may not prioritize urgent or important tasks effectively.
  • Cyclic Scheduling: Assigning automated mobile robots to follow a predetermined cycle of tasks repeatedly. May be useful for routine tasks, but lacks flexibility for handling unexpected events or changes in demand.
  • Hybrid Approaches: Some systems combine aspects of manual and rule-based scheduling, allowing for some degree of automation while still allowing human operators to intervene and make adjustments as needed.

The Costs of Inefficient Resource Scheduling

The limitations of manual and rule-based scheduling have direct impacts on the bottom line of life sciences and healthcare organizations, including:

  • Delayed Lab Results: For clinical laboratory automation, errors in manual scheduling of resources can lead to delayed specimen delivery, causing longer test-result turnaround and impacting patient care. A delay of even a few hours can translate to thousands of dollars in lost revenue for the lab.
  • Wasted Resources: In a hospital setting, underutilized AMR automation solutions due to inefficient rule-based scheduling can result in unnecessary capital expenditures. Optimizing AMR utilization can lead to cost savings in the range of tens of thousands of dollars per year.
  • Increased Labor Costs: In a pharmaceutical facility, manual adjustment of rule-based schedules can increase labor costs by thousands of dollars annually. Implementing a more adaptable scheduling system can free up staff for more value-added tasks.

The Power of AI-Driven
Task Assignment

Modern-day facilities face increasingly complex and unpredictable demand cycles, making adaptable task assignment a key component of any incorporated automation solution. Efficient scheduling is essential for timely material transport, limited workflow downtime, and better research outcomes.

By harnessing intelligent automation, AI scheduling offers an approach for robot task management that addresses the limitations of traditional methods.

Why Use AI-Driven Task Scheduling for Mobile Robots

Integrating artificial intelligence into the task assignment process of mobile robots allows facilities to leverage intelligent automation for the scheduling of their entire robot fleet.

Unlike manual and rule-based methods, AI scheduling continuously learns and adapts, applying its knowledge to make decisions based on real-time data and conditions. This intelligence technology is particularly valuable in dynamic industries with unpredictable day-to-day automation needs, including laboratories, hospitals, and warehousing facilities, where efficient scheduling of resources is critical.

What sets intelligent automation solutions apart is their ability to incorporate real-time data into its decision-making. This includes variables such as:

  • Sample Urgency: Prioritizing sample processing based on time-sensitivity.
  • Robot Status: Monitoring battery levels, maintenance needs, and overall robot health for proactive task reassignment that prevent delays.
  • Environmental Factors: Considering foot traffic patterns, equipment availability, and and even personnel schedules to optimize workflow.

What is Artificial Intelligence (AI)?

Artificial intelligence (AI) is a broad umbrella term. It encompasses several groups of algorithms which, together, enable machines to simulate human cognitive functions like learning, reasoning, and problem-solving. Each group powers a specific ability of the intelligent robot, like object recognition, obstacle avoidance, language processing, decision-making, and many more.

These algorithm groups continuously interact and exchange information with each other as the robot functions, creating a unified intelligent automation system. Meanwhile, Artificial Intelligence, as a discipline, provides the framework and overarching control for all of the AMR’s intelligent capabilities — including AI-driven task assignment.

‘Machine Learning’ types of algorithms are primarily responsible for enabling AI-driven task scheduling, but several other algorithm types play supporting roles, including:

  • Decision-Making Algorithms: make real-time choices about task allocation, route optimization, and responding to unexpected events, based partially on Machine Learning data.
  • Optimization Algorithms: optimize the assignment of tasks to robots and determine the most efficient routes to minimize travel time and energy consumption.
  • Pathfinding/Routing Algorithms: determine the best path for robots to navigate complex environments, considering obstacles, traffic, and the physical constraints of the robot.

What is Machine Learning (ML)?

Machine learning (ML) is a group of artificial intelligence algorithms that enables systems (in this case, AMR robots) to learn from and make predictions & decisions based on data.

This learning process happens without explicit programming for each dataset. Instead, the integrated intelligence algorithms of ML analyze the data, identify patterns, and use those patterns to make inferences or take actions.

For AI-driven task scheduling in AMR robot fleets, the roles of machine learning include:

  • Learning and Improvement: ML algorithms analyze historical data and learn from past performance to refine the system’s decision-making over time in areas of task allocation, route planning, and overall system efficiency.
  • Predictive Modeling: ML can forecast future demands and optimize task scheduling to proactively meet these needs.
  • Adaptive Behavior: ML enables the system to adapt to changing conditions in the environment, such as new obstacles or revised priorities.

Machine Learning algorithms often operate as a component within a larger Decision-Making system. For instance, an ML model might predict the time it takes to complete a task, but a separate Decision-Making algorithm could use that info

Interaction of AI and ML in AI-Driven Task Assignment

The interaction between algorithms can be complex, with multiple factors being considered simultaneously to make optimal decisions. Many of these processes happen in parallel, allowing for quick responses and efficient task execution. In addition, this process isn’t just a one-time sequence – it’s a continuous feedback loop, with ML constantly learning and refining the system’s decision-making over time.
