At first glance, the Bionic Handling Assistant looks like a pliable gripper arm with a structure and overall function modelled on an elephant’s trunk. Our researchers also use the system as a development platform that combines a wide variety of technologies and components.
At the same time, the system serves as a multi-technology platform for the simultaneous development of mechanics, electronics and software for machines and handling solutions. In 2012, our engineers added image and voice recognition to the assistant. This enabled the system to grip objects on its own – without the need for programming work or manual operation.
This continuous development shows how the Bionic Learning Network is an integral part of our innovation processes. Together with a wide variety of partners, natural principles provide us with new inspiration for technical applications and the industry of tomorrow. The Bionic Handling Assistant is a joint project with the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA).
Both the gripper and the bellows structure of the gripper arm are made of polyamide using the selective laser sintering process (SLS). The generative production method allows engineers to design individual movable system parts that are difficult to achieve with conventional technologies.
At the beginning, the material is in powder form and is applied to a construction platform in thin layers during the production process. Each layer is fused to the underlying layer with a laser and only cured where the program requires it. In cavities, the powder does not harden and can therefore be removed later. This enables individual 3D printing of complex products and designs.
