Rapid Prototyping in the development of robot hardware

April 29th, 2024 | by

As part of the RobWeld project, new wrists and gripping mechanisms were developed for the PARAGRIP developed and built at IGMR.Through iterative design processes using rapid prototyping in 3D printing, we have perfected functionalities, ease of assembly and the manufacturability of components. The result? An elaborate design that combines steel and aluminum components.In the next step, the design can now be extensively tested before it is used on the robot.

Technology included – exoskeletons & co. – aids for everyday working life

April 22nd, 2024 | by

A successful day for the IIDEA project at the IHK and HWK event “Technology included – exoskeletons & co. – aids for everyday working life”! Prof. Hüsing and our project manager Carlo represented the IIDEA project at the event in Düsseldorf. Prof. Hüsing gave an exciting presentation on “Inclusive working environment through collaborative robotics: opportunities and perspectives for your company.” At the stand in the foyer, we were also able to inspire many organizations and companies for our project. We look forward to visiting them soon and working together on inclusive working environments!

Development of an active dynamic balancing unit for pick and place applications

April 18th, 2024 | by

Delta robots are the most common parallel robots for manipulation tasks. In many industrial applications they must be operated at reduced speed or dwell times have to be included in the motion planning, to prevent frame vibrations. As a result, their full potential cannot be realized. To address this problem, this we developed the mechanical and control design of an active dynamic balancing unit for reduction of frame vibrations. In this video you can see the experimental validation of this system in a pick and place scenario. It the proposed active dynamic balancing unit provides a significant vibration reduction of about 85% for translational and 78% for rotational vibrations. The experiments were conducted on a low cost Delta robot called the Suisui Bot designed at the IGMR, in collaboration with the Tokyo Institute of Technology. Two different strategies have been proposed for the control of the balancing unit. In this video you can see the IMSC in combination with a open-loop control based on the robots inverse dynamics. Please refer here for further information on the design and control system.
