How to choose the right warehouse robot for you
A strategic approach to starting the journey to material handling automation should begin with a comprehensive evaluation of your operational landscape. This critical phase encompasses an in-depth analysis of operational challenges, the exploration of viable solutions, the identification of potential pilot locations, and a meticulous examination of the return on investment that can be garnered from the automation of your material handling processes.
Categorizing automation solutions based on payload size and type is the next foundational step. Begin by looking at whether your workflow involves the movement of orders and materials through pallets, bins, or carts. Determining the average dimensions and weight of these payloads helps you refine the selection of viable material handling equipment. This should primarily focus on processes that are labor-intensive, maximizing the impact of automation.
Another pivotal aspect of initiating the automation journey is to prioritize functions that have substantiated case studies and success narratives. Examples of such functions include dock-to-stock operations, order picking, packaging for outbound shipments, and the facilitation of replenishment and deliveries to pick/pack lines, kitting, and value-added services. Numerous other extensively documented use cases are accessible, especially within manufacturing scenarios. These span from Kanban replenishment and lineside operations to kitting milking runs, WIP (Work in Progress) management, and Assembly Line Delivery.
Rather than attempting to tackle the most challenging problems head-on, it’s best to focus on the most scalable opportunities – those that can be easily replicated once shown to be successful. Avoid customization (at least initially) because it can be much more expensive and usually has a longer payback period. You also want to be aware of space constraints because robots function a lot differently than people – adaptations might be required to accommodate the spatial requirements of automated equipment.
Make sure you allocate time to research and review as many case studies as you can find on automation in industries like your own. It’ll help you identify the use cases with the highest potential for return and the most successful implementation. All in all, you can help to optimize your own journey into material handling automation careful planning, prioritization of scalable opportunities, and a holistic understanding of equipment, space, and return dynamics.
