DOBOT AMB 300 - Autonomous mobile manipulator with CR10A robot

One of the main advantages of the mobile manipulator is that it connects logistics and production operations within one automated workflow. A conventional AMR typically transports a load from one point to another, where an operator or separately installed automation system must take over. The AMB-300 with CR10A, by contrast, can interact directly with the workpiece once it reaches its destination. DOBOT positions its AMMR platform for applications including machine loading and unloading, wafer handling, inspection and internal industrial material transport.

The AMB-300 uses Laser SLAM navigation, eliminating the need for embedded guidance wires, magnetic strips or other fixed route infrastructure. The platform autonomously navigates between defined work locations using a digital map of its environment, while routes can be modified through software if the production layout or workflow changes. The manufacturer specifies support for single-frame maps covering up to 200,000 m².

The AMB-300 mobile platform provides a maximum load capacity of 300 kg. This offers sufficient capacity for the integrated CR10A robot arm, its control components, the selected gripper or other end-of-arm tooling, cameras, sensors, workpiece fixtures and additional automation peripherals. The modular architecture of the DOBOT AMMR system allows the mobile platform, robot arm, machine vision and end effector to operate as one coordinated automation solution.

According to the manufacturer’s AMB-300/300D specifications, the platform measures approximately 1000 × 700 × 793 mm without the robotic arm, has a rotation diameter of 1040 mm, weighs approximately 144 kg including the battery and requires a minimum aisle width of 840 mm. The mobile platform can navigate at speeds of up to 1.4 m/s. According to DOBOT, the embedded Laser SLAM algorithm provides repeatability of up to ±5 mm and relative positioning accuracy of ≤±2 mm, allowing the system to return reliably to the same machine, workstation or transfer point.

Manipulation is performed by the included DOBOT CR10A. The CR10A is a 6-axis collaborative industrial robot arm with a maximum payload of 10 kg and a working radius of 1300 mm. Its ±0.03 mm repeatability makes it suitable for handling larger workpieces, heavier end effectors and applications requiring a wider local working area than smaller mobile manipulator configurations.

The 10 kg payload is particularly valuable in machine-tending applications, where the robot must carry both the workpiece and its end effector. Larger pneumatic or electric grippers, vacuum systems and specialised tooling can account for a significant part of the available payload, so the higher capacity of the CR10A provides greater flexibility when designing the complete mobile manipulation system.

The 1300 mm working radius is another significant advantage. Once the AMB-300 reaches a workstation, the CR10A can cover a relatively large local area without requiring the mobile base to reposition for every individual movement, making it ideal for servicing larger CNC machines, multi-fixture stations or wider conveyors.

The higher-capacity robot arm can also enable several smaller workpieces to be handled simultaneously when equipped with an appropriate multi-position gripper. This can increase the amount of work completed during each visit to a machine or workstation, particularly in repetitive manufacturing and material-handling processes.

The CR10A supports hand-guided teaching and graphical programming, simplifying configuration for different workstations. An operator can physically guide the robot into the required positions and save those positions as part of the automated process.

The CR10A arm itself weighs 40 kg, features IP54 protection and operates in ambient temperatures from 0 to 50 °C, ensuring stable and reliable performance on the mobile platform.

The extended operating time of up to 12 hours is particularly valuable in applications where the mobile manipulator moves between numerous tasks across one or more shifts. The AMB-300/300D platform uses a 48 V, 52 Ah lithium battery and supports manual, automatic and quick charging. According to the manufacturer’s documentation, charging from 10% to 80% takes no more than approximately 2.5 hours.

With an automatic charging strategy, the system can return to a charging station during idle periods or when the battery reaches a defined level. This supports higher availability without requiring an operator to connect the robot manually for every charging cycle.

Safety is ensured by P+F R2000-HD LiDAR units, dual encoder speed monitoring, proximity sensors, emergency stop buttons, audible buzzers, and a protective safety rim.

The AMB-300/300D platform has an IP20 protection rating and is designed for operation between 0 and 50 °C and 10–90% non-condensing relative humidity in indoor manufacturing and logistics environments.

The mobile platform also provides extensive electrical and network connectivity. Specifications list seven 24 V output channels, ten PNP/NPN digital inputs, and three RJ45 Gigabit Ethernet interfaces, together with Wi-Fi 802.11 a/b/g/n/ac wireless connectivity.

The integrated architecture supports wafer handling, intralogistics transport, and power and equipment inspection (power inspection) across diverse industrial settings.
