Over the past few decades, a remarkable surge in innovations spanning robotics, Artificial Intelligence, and the Internet of Things has spurred the development of ‘smart warehouses.’ With the aid of emerging technologies, smart warehouse robots facilitate the automation of inventory movement within warehouse premises, minimizing the need for extensive human intervention and optimizing operational workflows. Let’s delve into the multifaceted role of warehouse robots.
What is Warehouse Robotics?
Warehouse robotics encompass autonomous machines designed to execute particular functions within a warehouse or distribution centre. Their primary objective is to alleviate human workers from repetitive and hazardous duties by employing intelligent automation in warehouse management. By integrating physical machinery with advanced software, these robotic systems empower warehouses to achieve elevated levels of efficiency compared to manual processes, while concurrently enhancing the environmental conditions within the facilities themselves. The robots are programmed for tasks such as receiving, sorting, material transportation, stock replenishment, as well as the execution of picking, packing, waste management, and facility space optimization.
Warehouse Robotics: A Page in History
Supply chain robotics originated in manufacturing, with George Devol filing the inaugural robotics patent in 1954, ultimately leading to the production of the first industrial robot by his company, Unimation, in 1956. These early robots had limited mobility, generally moving over short distances. General Motors joined the robotics movement in 1962 when they installed their first robot in a New Jersey plant. Initially, robots were confined to industrial manufacturing due to safety concerns. The earliest robots were large robotic arms, primarily designed to handle hazardous or strenuous tasks, like welding and heavy lifting, to mitigate job displacement concerns.
Types of Warehouse Robotics
Today’s warehouse robotics encompass both stationary and mobile robots, each offering distinct advantages. The choice of the ideal robotics solution depends not only on your current operational scale but also on your long-term objectives. Here are the common categories of warehouse robotics:
- Automated Guided Vehicles (AGVs):
AGVs and their smaller counterparts, Automated Guided Carts (AGCs), handle inventory transportation within warehouses. Typically, they follow magnetic stripes or predefined tracks on the warehouse floor. Some AGVs operate without a track and incorporate safety scanners, making them compatible with manual vehicles. They possess warehouse maps and inventory location data. For instance, a Belgian logistics company, adopted AGVs to enhance efficiency and productivity in their large warehouses. This transition reduced time spent on manual material movement and allowed round-the-clock operations. AGVs require just 8 minutes for recharging, ensuring minimal downtime, and their cost-effective performance enabled a return on investment within a year of implementation.
- Autonomous Mobile Robots (AMRs):
AMRs enhance efficiency, accuracy, and security during sorting. These robots also reduce repetitive tasks, freeing human workers for more creative roles. They provide consistent accuracy, even in monotonous processes, resulting in higher inventory accuracy. AMRs can be employed for daily inventory cycle counts, increasing data accuracy and discouraging inventory theft.
- Aerial Drones:
Similar to AGVs, AMRs use sensor technology for inventory transport but do not rely on preset tracks or routes. AMRs navigate autonomously through onboard sensors, computers, and maps. These agile robots can identify package information and sort with precision, creating dynamic routes based on operational needs. They can adapt to changing conditions and avoid obstacles. Aerial drones have garnered attention since Jeff Bezos introduced Amazon’s drone delivery concept in 2013. While drone delivery is still in the experimental stage, drones hold immense potential in the logistics industry. Drones optimize warehouse inventory processes by swiftly scanning locations for automated inventory management. They can seamlessly integrate with warehouse management systems (WMS) for access to inventory information. Aerial drones navigate without markers or lasers, using optical systems, deep learning, and computer vision. They efficiently scan inventory, whether high or low and upload precise data directly into the warehouse inventory management software. These drones are adept at reaching challenging and hazardous areas quickly, without occupying warehouse space or interfering with personnel and other robots.
- Automated Storage and Retrieval Systems (AS/RS)
Automated Storage and Retrieval Systems (AS/RS) represent a technology designed to facilitate the movement of inventory into and out of storage. Typically, these systems are coupled with warehouse execution software that orchestrates their operations. AS/RS solutions come in various configurations, tailored to specific tasks, system requirements, and the types of goods they handle. They can function as shuttles moving on fixed tracks or cranes manoeuvring between aisles. Notably, some newer models, like the Skypod, are capable of navigating aisles to retrieve customer orders. One of the world’s largest retailers demonstrated the effectiveness of AS/RS at their Chinese warehouse. Leveraging a fleet of 60 robots, they achieved a remarkable 70% reduction in warehouse labour requirements. These robots operate through Wi-Fi connections, delivering inventory to workers for packaging and shipment. The outcome was a threefold increase in operational efficiency and output.
Benefits of Adopting Robotics in Warehouse Management
- Reduced Error Rates: Minimizing errors is paramount for businesses, as human mistakes can lead to costly rework and profit loss. Robots, on the other hand, offer a consistent track record of accuracy from the outset, driving down warehouse costs by getting the job right the first time, every time.
- Adaptable Workforce: The retail industry experiences both peak and off-peak seasons, making workforce adaptability crucial. Robotics provide warehouses with the agility to swiftly meet increased capacity demands. During peak times, such as the holiday season, the rapid recruitment and training of human employees to match demand forecasting results can be challenging. Robotics offer a solution by operating around the clock without performance degradation, ensuring operational continuity.
- Enhanced Warehouse Safety: Warehouse robotics contribute significantly to improved workplace safety. They assume responsibility for hazardous tasks that pose risks to human workers. As robots can now effectively collaborate with humans, they can shoulder more perilous duties, including retrieving inventory from heights or transporting heavy loads. Beyond safety enhancements, the introduction of robotics results in increased worker morale, as monotonous and dangerous tasks are alleviated from their responsibilities.
- Elevated Customer Satisfaction: The combination of expedited delivery and reduced error rates naturally leads to heightened customer satisfaction. Exceptional customer service is a cornerstone of business growth. The ability to execute flawless operations at an accelerated pace enhances customer loyalty and attracts new business. Leveraging robotics not only bolsters order fulfilment but also provides your workforce with additional time to focus on enhancing the overall customer experience. Automation streamlines packaging, communication, and follow-up, enhancing the customer’s interaction with your company.
