Goods to Person

Goods to person

goods-to-person (GTP). Accelerate throughput. Drive omnichannel. 

Choice and speed are the watchwords of today’s omnichannel retail model – presenting the fulfillment operations of leading retailers with big challenges. But fast fulfillment can’t be met with fixed infrastructure and rigid automation built for a previous era. From putaway all the way to picking, efficient fulfillment must be automated.


Switch from rigid and slow → to smart and swift

Introducing Ranger Rack-to-Person (RTP) – the goods-to-person autonomous mobile robot (AMR) – for automated putaway, inventory storage, replenishment and order picking in fulfillment and distribution centers.

Powered by the GreyMatter fulfillment operating system, Ranger RTP is configured to operate with mobile storage units (MSUs) and the static pick-put and roll-cage pick-put station accessories available for Ranger products. All designed to allow the warehouse’s robots and human workforce to collaborate efficiently.

Ranger RTP capabilities

  • The Ranger RTP automation system adapts seamlessly to changing inventory profiles, demand patterns, and peaks
  • Modular system architecture ensures bi-directional scalability to increase storage volume or fulfillment throughput independently by adding more storage racks or robots as needed.
  • From reducing travel time by 5x that of human workers to reconfiguring mobile stock units (MSUs) – and working in tandem with other GTPs and Ranger Pick – the result is fluid, dynamic optimization.
