Lightweight manipulators and automated guided vehicles are currently used in many areas of industry. However, because the work space of manipulators is often severely restricted, application potentials can be significantly extended by combining both systems to create a mobile manipulator. For example, mobile manipulators can help workers at your assembly stations. Because they are not fixed, they can move around from one place to another.
Expertise and sample projects
Developed at Fraunhofer IPA, the mobile manipulator “rob@work 3” integrates all components for all sub-areas of service robotics onto an omnidirectional platform that guarantees mobility even in cramped industrial conditions. On the basis of natural and/or artificial landmarks, the system navigates its way around using different combinations of sensors (e.g. 2D/3D cameras, laser scanners, IMU, RFIDs, indoor GPS). A synchronized control of the mobile platform and manipulator extends the work space. The mobile platform enables the lightweight arm to move around an object. For example, an adhesive or sealant can be applied all around the object in an uninterrupted process. Under normal circumstances, this would be impossible due to the limited range of the robot’s work space.
The respective software for the two-arm assistive system allows collision-free planning of the arm in space. All interfaces are available to users as part of the open source project ROS (Robot Operating System).
The goal of the project PRACE was to develop highly-adaptable two-arm mobile robot systems that are especially suited for manufacturing small product series. These fulfill the increasing demands for flexibility in production. It is important that the robot moves in a similar way to its human counterpart and at the same speed. It can learn this by demonstration.
