Why Choose Autonomous Mobile Robots?               

AMRs are powerful tools, but if your current operation is broken, they’ll only accelerate the problems. That’s why it’s critical to work with warehouse experts before making a move.

Before anything hits your floor, we simulate movement paths, map your space, and design the system to match your workflows, avoiding problems before they start.

When you're ready to scale, the benefits are clear:

 

  • Labor Efficiency

  • Scalable Deployment

  • Increased Safety

  • Operational Flexibility

  • Reduced Operating Costs

Compact underride AMR with an independently rotating lift plate. This is the unit HOJ runs on its own floor.

Technical details

The SJV-SW600 is SEER's most popular light-load jacking robot. Its body and lifting platform rotate independently, so the chassis can spin under a rack to align or turn a load without moving the rack itself, a real advantage in dense shelving and narrow aisles. Front navigation lidar plus rear obstacle-avoidance lidar give 360° coverage.

  • Footprint 950 × 650 × 250 mm; rotation diameter 1,015 mm; min. aisle 790 mm
  • Laser SLAM standard; QR-code and reflector navigation optional; ±5 mm / ±0.5°
  • Speed ≤1.5 m/s loaded (2 m/s unloaded); 48 V / 24 Ah LiFePO₄, ~8 h, 10–80 % charge ≤2 h
  • Auto-charging, shelf recognition, spin function, Wi-Fi roaming; E-stop, bumper, speaker, ambient lamp

HOJ + Geekplus Robotics

HOJ Engineering is partnered with Geekplus, the world's No. 1 warehouse AMR provider with 72,000+ robots deployed, to qualify, size and configure goods-to-person and sortation systems as part of our warehouse study program.

Shelf-to-Person (P Series)Robots bring whole shelving units to the picker

Geekplus's flagship system and the one it leads the market in. P Series robots lift a mobile shelf and drive it to a workstation so pickers never walk the aisles. Deploys on any flat floor with no fixed infrastructure.

  • Models P500R, P800R, P800R V6 (slim), P1200R; 500 kg to 1,200 kg payload
  • Up to 4.5 m/s; 60 mm lift; 99.99% picking accuracy
  • Typically cuts picking labor 50 to 70 percent

TÜV-certified safety

Ask HOJ if shelf-to-person fits your operation

Tote-to-Person (RoboShuttle)High-reach bin robots for dense tote storage

RoboShuttle robots work narrow aisles, pull individual totes from tall racking with telescoping forks and deliver them to a workstation. Roughly 2.5x the storage density of a manual operation.

  • Models C200M, C200S and the RS series (RS Hyper launched 2026)
  • First bin-to-person system certified to both CE and ETL (UL 3100), Intertek-tested

Robotic Sortation (S Series)Mobile sorting robots for parcels and returns

Sorting robots carry one parcel each across a flat sort floor or mezzanine and drop it into the destination chute. Capacity grows by adding robots, not rebuilding a conveyor loop. HOJ designs these alongside our conveyor and tilt-tray sortation options.

  • Hundreds of destinations on floor-level or mezzanine grids
  • Parcels, polybags, apparel, returns

Ask HOJ about robotic sortation

Pallet-to-Person and Transport AMRsPallet retrieval, forklift and moving robots

For full-pallet and heavy-load flow, Geekplus offers pallet-to-person storage plus its M and F series transport and forklift AMRs. HOJ evaluates these side by side with the SEER forklift and lifting robots above so you get the right unit for the load.

FAQs

What’s the difference between AMRs and AGVs?

AMRs use onboard sensors and AI to navigate dynamically, without fixed paths or guide wires. They’re more flexible and easier to deploy than traditional AGVs.

Can AMRs work in existing facilities?

Yes. AMRs are designed to adapt to existing layouts with minimal changes. We map your facility and customize routes to fit your current operations.

How are AMRs kept safe around people?

AMRs use onboard sensors, cameras, and AI-based obstacle detection to safely navigate around people, forklifts, and other equipment in real time.

What training is included?

HOJ provides full on-site training during deployment. Your team will learn how to operate the control software, monitor performance, and manage day-to-day tasks.

How fast is deployment?

Most AMR systems can be installed and operational in weeks, not months. Timelines vary based on complexity, but our turnkey approach keeps projects moving quickly.

What does the process look like if we want to move forward with AMRs for our facility?

Our process is designed to ensure the AMRs integrate seamlessly with your operations:

  1. Consultation & Site Mapping – We start by understanding your workflows and mapping your facility using CAD drawings or site scans to simulate robot paths and flag complex zones.

  2. Setup Locations & Sequences – We assign map points and define any custom actions for the AMRs.

  3. Custom Configuration – Our team builds a tailored operator interface and tests your setup before deployment.

  4. On-Site Deployment – We arrive onsite to commission the robots, verify accuracy, and finalize calibrations.

  5. Training & Support – After go-live, we stay to observe, adjust edge cases, and train your team on use and maintenance.

  6. Ongoing Support – Optional maintenance contracts include upgrades, remapping, and a flexible support pool.

How long does it take to get AMRs up and running?

Onsite setup typically takes 1–2 weeks, but the biggest variable is upfront planning, customizing interfaces, integrating with your systems, and simulating movement before anything arrives on site.

What services do you offer for companies interested in AMRs?

We provide full-service AMR integration, from system design and simulations to installation and support. If you prefer to handle parts of the project internally, we can step in where it makes the most sense for your team.
