Autonomous mobile robots (AMR)

Autonomous mobile robots such as STILL’s AXH iGo and ACH iGo series are small, manoeuvrable and intelligent underride vehicles that operate flexibly and proactively in complex warehouse structures. These can be used as a stand-alone solution or integrated into existing warehouse management and control systems to suit the customer’s requirements. Compared to classic automated warehouse solutions, AMRs can be integrated cost-effectively into existing environments and systems. Operating and maintenance costs are also comparatively low. To decide on the vehicle concept that best suits your specific needs, it is important to evaluate various criteria. These include, for example, the infrastructure, environment and volume of traffic in the warehouse, the need for buffer storage and the type of load, not to mention the cost implications. STILL’s experienced automation experts will support you in analysing your processes, evaluating the relevant criteria, selecting the right system as well as planning and implementing it. Our perfectly coordinated service concept, a comprehensive service network and the expert knowledge of specially trained service technicians ensure the availability of your system.

ACH iGo:

  • High throughput with low space requirements
  • Especially compact thanks to on-the-spot carrier rotation
  • Easy to integrate into new, optimised process landscapes and in areas designed for the ACH
  • Flexible transport of different carriers in tight spaces

AXH iGo:

  • Robust solution for dynamic mixed transport
  • Safe load transport incl. flexible loading thanks to position detection via camera
  • Efficient transport solution with obstacle circumnavigation for long distances
  • Smart commissioning tools for individual hall layouts

Application examples for the STILL AXH iGo in intralogistics

Autonomous mobile robots (AMR) are already used in various industries today: e.g. parts supply for production, the automotive industry, logistics, medical manufacturing, clothing or electronics production, and e-commerce.

Goods transport with trolleys: When transporting goods using trolleys, the AXH iGo transports the entire unit from A to B. The innovative 3D camera ensures flexible lifting of the goods before they are loaded onto the AXH iGo as well as precise unloading at the desired destination.

Goods transport with pallets: When transporting goods using pallets, the AXH iGo picks up the pallet and its goods from a specified transfer station and transports it to its end station. Prior to unloading at the end station, the AXH iGo checks whether the transfer station is free for the goods to be unloaded using the innovative 3D camera.

Goods transport with grid box and adjustable rack system: When transporting goods using a grid box and individually adjustable rack system, the goods are flexibly loaded and transported to their destination. Depending on customer requirements, flexible transport options can be provided that also incorporate the use of a trolley.

The STILL AXH iGo in practice

Continuous development as a benchmark: Gradual automation using autonomous mobile robots.

U. I. LAPP GmbH recently opened its new logistics centre in Hanover. Since then, industrial trucks from STILL have been increasing the level of automation with their smart assistance systems – and thus also increasing safety and efficiency. Now the company is taking the next step in this direction. The company is testing an implementation of the STILL AXH autonomous mobile robot in the intralogistics processes of the new distribution centre, the medium-term goal being the gradual automation of the company’s intralogistics.

Application examples for the STILL ACH iGo in intralogistics


Goods transport via a loading platform (table): When transporting goods via a loading platform (table), the ACH iGo transports the entire unit from A to B. The goods are placed on the loading platform. The ACH iGo drives under the element, lifts it, transports it to its destination and deposits it there. If a conveyor trolley is used as the goods carrier, additional positioning measures may be required.

Goods transported directly on the vehicle: With direct goods transport, the goods carrier is transferred from the transfer station directly to the ACH iGo. The ACH iGo drives under the loaded station, lifts the pallet with its adapter plate and transports it to the destination. The station is refilled.

Transports individual carriers: Depending on the customer’s requirements, individual transport options (including a multi-level loading platform, conveyor trolleys or trolleys) are possible, e. g. for different carrier dimensions or transport orientation. If a conveyor trolley is used as the goods carrier, additional positioning measures may be required. Our STILL experts will implement a bespoke transport solution to suit your needs based on your specifications.

Battery technology for autonomous charging

All STILL AMRs are equipped with lithium-ion batteries to ensure constantly high performance and availability thanks to simple interim charging. Multiple devices use the same fixed charging station to charge their batteries at different times. When it reaches a state of charge (SOC) of 30 % the vehicle autonomously initiates charging, then stops charging when it reaches an SOC of 90 %. This preserves the battery and ensures an optimum service life.

The ACH iGo charging device uses a connector. The vehicle reverses onto the charging station with the help of QR codes and docks with the connector.

The AXH iGo charging device has charging contacts on which the vehicle positions itself and aligns itself precisely.
