Successful completion of our DFG project: Multidirectional additive manufacturing with the plasma welding process

August 20th, 2024 | by

We are pleased to announce that we have successfully completed our DFG-funded project in cooperation with the Institute of Welding and Joining Technology RWTH Aachen University on multidirectional additive manufacturing with the plasma welding process!

Highlights of the project:
– Process control through unified process monitoring and control in ROS: Thanks to the use of the Robot Operating System (ROS), we were able to realize high-precision process monitoring and control. This ensures optimum process reliability and repeat accuracy.

– Multidirectional trajectory planning: By developing and implementing our path and trajectory planning, we have succeeded in enabling complex welding movements for production. This increases the flexibility and variety of possible applications within additive manufacturing.

– Stable deposition possible even on inclines thanks to workpiece handling: Our solution for workpiece handling makes it possible to achieve stable layer deposition even on inclined surfaces. This expands the areas of application and significantly improves the quality of the manufactured parts.

A big thank you to the entire team for the outstanding collaboration and to the German Research Foundation (DFG) for supporting this groundbreaking project. We are looking forward to the future developments and applications of our research results in industry!

As part of the ErgoFli project, an innovative system is being developed in collaboration with project partners to help tile layers make their work more ergonomic and efficient.

In the video you can see how the system works in the Gazebo simulation environment. The robot automatically removes tiles from a magazine and matches them perfectly to the tiles already laid. With automatic processes, several tiles can be laid in succession to optimize the work process.

Our aim is to create a tool that not only reduces the workload for tilers, but also improves their working environment. We are excited about the progress and look forward to sharing more insights with you soon!

IMBA training for the IIDEA project team

May 7th, 2024 | by

Our IIDEA-project team took part in a training course on the “Integration of people with disabilities into the world of work” (IMBA).

IMBA is positioned at the interface of medical and occupational rehabilitation and enables a precise description and comparison of work requirements and human abilities. The training covered the basics of IMBA, with a particular focus on the defined characteristics that serve as the basis for the assessment of work requirements and abilities. A highlight of the training was the introduction to the “Marie Plus” software, which is closely linked to the IMBA concept. The training was conducted by Torsten Alles, Ph.D., Managing Director of iqpr. His extensive knowledge and experience helped to emphasize the importance of IMBA in occupational therapy and activity-based medical rehabilitation.

We are convinced that this training will support our previous research and make a valuable contribution to the IIDEA project. We are grateful for the expertise we have gained through this training and look forward to applying the acquired knowledge in our daily work.

Robot Cooking – Transferring observations into a planning language

Transferring observations into a planning language: An automated approach in the field of cooking

In the Robot Cooking project, an automated method is developed to analyze and identify motion data and convert it into a machine-readable planning language. This is done using a cooking scenario as an example in which the motion data is captured by recording the hand pose of the cook.

The recording is done using a motion capture system consisting of seven cameras and a glove with three markers on the back of the chef’s hand. The position of the markers is determined by triangulation. This provides enough information to derive the hand pose. The recording is done at 120 frames per second. Before the cooking process, all objects in the workspace are identified and their initial positions determined. Motion data is continuously recorded and converted into poses with time stamps. Additional information such as velocity, acceleration and angle in relation to the tabletop are derived from the raw data.

A initial structure of the dataset is created by finding the side actions using classification. Here, pick, move and place are identified as recurrent side actions. A separate training dataset is used to train a classifier that recognizes these actions. This enables an easier analysis of the remaining actions.

Clustering is applied to identify unknown actions. A dynamic approach allows analysis despite high variability in execution. A unique fingerprint for each action is found, based on the orientation of the back of the hand and its speed on the table plane, to assign each frame to a cluster and finally to an action.

The knowledge gained from classification and clustering is translated into a machine-readable Planning Domain Definition Language (PDDL). A schedule is created, with known actions directly assigned. Start and end positions are specified, and virtual object tracking is used to represent the progression of objects during cooking. For unknown actions, preconditions and effects are handled dynamically. The results are translated into a machine-readable PDDL. This formal representation enables efficient automatic scheduling and execution of the previously demonstrated cooking task.

Additional information is available in the video linked above, the poster and the paper.

Situational adaptive movement prediction for firefighting squads in indoor attack

July 6th, 2023 | by

We presented our paper “Situational Adaptive Motion Prediction for Firefighting Squads in Indoor Search and Rescue” at ICRA in the Long-Term Human Motion Prediction workshop.

Firefighting is a complex but poorly automated task. To minimize ergonomic and safety risks for firefighters, robots could be used in a collaborative approach. To enable human-robot teams in firefighting, important fundamentals are still missing. Among other things, the robot must predict human movement because occlusions are ubiquitous. In this work, we propose a novel motion prediction method for firefighting squads in indoor attack. Squad paths are generated using an optimal graph-based planning approach that represents firefighter tactics. Paths are generated on a per-room basis, allowing dynamic local adaptation of paths without global replanning. The movement of individual agents is simulated using a modification of the Headed Social Force Model. We evaluate the feasibility of the pipeline using a novel dataset generated from real footage and show its computational efficiency.
