t-Rail is a dual-purpose robotic transport system.  It is used for retail / grocery store transport to deliver goods to and from the selling floor for multiple process flows.  It can also be used for a warehouse environment for tote or bulk transport of goods.  In both cases, t-Rail is positioned overhead to avoid floor level traffic and congestion.


When used for store-based retail, used as an overhead transport carrying totes, cases, loose items or orders to customers.  Ideal for supercenters, grocery, mall anchors, club stores or large retail.

When used in a warehouse, can carry one or more packages or cartons of varying sizes through the warehouse without interruption to floor-level operations.  Ideal for Distribution Centers and Fulfillment Centers.

Retail Store Applications

In its store-based mode, t-Rail is an overhead transport robot capable of carrying totes containing cases, loose items, or orders for a customer.  With its elevated design, t-Rail allows for continuous movement without disruption to floor-level activities and greatly minimizes aisle congestion, blocking of shelves by gondolas, interference for shoppers, and eliminates all shopper / machine possible interactions.

Delivers items for shelf replenishment to specific aisle segments.

Delivers completed and packages orders to customer interface location (lockers, drive up window, area for carry out or walk-in).

Uses elevators nestled in aisle shelving structure to move goods between the floor level and the overhead t-Rail.

Ideally mated with a t-Sort for order sortation and fulfillment of units for customer orders and outbound sortation of e-commerce orders.

Delivers totes of picked items for BOPIS and e-commerce orders from individual aisle segments to the backroom for order fulfillment.  Allows an associate to pick all items in a single aisle for hundreds of orders as a batch and place into the t-Rail system

Ideal for supercenters, grocery stores, mall anchors, club warehouses, or any large format retail store setting.

Warehouse Applications

In its warehouse mode, the t-Rail is an overhead transport robot capable of carrying a wide variety of loads through warehouses and distribution centers with speed and accuracy.

Overhead design for continuous movement, no disruption to floor-level activities.  No traffic, congestion or movement obstacles.

Any type of DC, FC, shipping, processing environment.

Uses elevators or decline / incline sections to interact with the floor level operations.

In response to COVID-19 and limiting travel, Tompkins Robotics is now offering interactive virtual tours using a variety of stationary and roaming cameras throughout the facility.  We have the capability to demonstrate five t-Sort systems with various configurations, robots and functionalities.  The main demonstration system includes three different induction types: manual, robotic and A-frame.  Our systems are capable of e-commerce order fulfillment, store replenishment, backroom and parcel / postal sortation.  We can demonstrate the original t-Sort robotic system in multiple dual level configurations and an elevator system to move robots between the levels.  Our larger t-Sort Plus robots run on single level systems with both tilt tray and crossbelt options.  In the very near future we will demonstrate the new t-Sort Mini in an additional system. We have a wide variety of inventory to demonstrate products including general merchandise, apparel, grocery, fragile goods, odd sizes and shapes and a wide range of product weights.  You will also have a chance to learn about the technologies that are integrated into our system such as automated induction, automated charging, integrated weight and dimension capture, our proprietary wireless network and Warehouse Execution System (WES), new innovations such as our automated sorter exit solution and more.  And if mobility and flexibility are important to you, we can demonstrate how easy it is to reconfigure a system, remove or add a sort table, and even fold a table into a smaller footprint for move or transport.
