A lifting robot is a low-profile AMR that drives under a shelf, cart, or rack, raises it a few inches, and carries it to a workstation or line. It navigates by laser SLAM on your existing floor with no tape, wire, or reflectors. HOJ integrates the SEER Robotics lifting family: a rotating-top model, a 1,000 kg model, and a compact model for tight cells.

Key facts

• Laser SLAM navigation with ±5 mm repeat accuracy, no floor infrastructure
• Shelf recognition drives the robot under the rack and aligns before lifting
• SJV-SW600: 1,323 lb, rotating top keeps the load facing the same way in a turn
• SLR-1000EU: 2,205 lb, CE safety certified to ISO 3691-4
• AMB-300JZ: 661 lb, 25 in aisles, 10 minutes of charge for 1 hour of run time
• All three run on the SEER SRC controller and RDS fleet manager with MES and WMS integration

How does a lifting robot work?

Your WMS, MES, or a call button sends a task. The robot drives to the pickup, identifies the rack, and slides underneath. The platform rises about 60 mm (2.4 in), the robot carries the load at up to 1.5 m/s, and it lowers the rack at the destination to within ±5 mm. It then returns for the next task or docks to charge. Front and rear lasers and a bumper strip give 360 degree protection, and the robot stops when a person steps into its field.

Where are lifting robots used?

• Goods-to-person picking with mobile shelving units
• Line-side delivery of kitted parts carts in factory automation
• Work-in-process moves between cells in manufacturing
• E-commerce order consolidation and sortation feed
• Finished goods staging on rolling racks
• Empty cart and tote return loops

When is a lifting robot better than a tugger AMR?

A tugger pulls a train of carts along a route, so it needs a hitch, an operator or station to couple and uncouple, and turning room for the whole train. A lifting robot picks up one cart or shelf on its own, delivers it, and comes back empty, with no coupling and no train to clear an aisle. For the SJV-SW600 the top rotates independently of the drive base, so the load keeps its orientation through a turn in a 31 in aisle. Choose a tugger for long hauls of many carts at once. Choose a lifting robot for point-to-point moves, short cycles, and tight spaces. For pallets on the floor, see our autonomous forklifts.

Plan a lifting robot system

HOJ engineers and integrates lifting robots as an independent integrator. We map your cart and shelf sizes to the right platform, size the fleet from your task volume, and connect the robots to your WMS or MES. An SJV-SW600 runs on our own floor, so you can see it lift and rotate a loaded rack before you commit. Talk to an automation engineer.
