Parth Pethani, founder of whserobotics.com, is a mechanical engineer who has spent a decade at the intersection of WMS consulting, industrial engineering, and warehouse robotics. He walks through the step-by-step thought process operators need before investing in automation — starting with maximizing your existing WMS, understanding invasiveness scores for brownfield implementations, and knowing when pick-assist AMRs, goods-to-person systems, or robotic arms actually make financial sense for your operation.
TOPICS COVERED:
- Why operators should maximize their WMS before investing in robotics: slotting, batch picking, wave picking, and pick path optimization
- The invasiveness score: how to evaluate automation for brownfield warehouses that can't stop shipping orders
- Pick-assist AMRs (Locus, 6 River Systems): least invasive option that doubles or triples picking productivity from 60 to 120-180 UPH
- Goods-to-person solutions (Geek+, AutoStore, Exotec, GreyOrange): why concrete leveling, fire safety, fencing, and network connectivity add hidden costs
- Why robotics likes constant but warehousing is dynamic — and why 3PLs face different automation challenges than retailers
- Boston Dynamics Stretch and truck unloading robots: the most versatile use case for small and mid-size operators
- Auto baggers, automated packaging machines, and robotic arms for palletizing and unit sorter induction
- Why only 18-20% of warehouses have any form of automation and what that means for adoption timelines
