Workshops and foundries

For building our robot-systems we manufacture some components in our workshops and foundries. Here you can find some information about the following:

and especially:

Elektronic workshop

Contact person: Christian Schoo

Especially in the field of robotics, the requirements for electronic assemblies, e.g. in terms of size, geometry or external conditions, are high. The equipment in the electronics laboratory makes it possible to produce assemblies in-house in a short time that are precisely adapted to the requirements in the respective projects. The electronics laboratory is equipped with devices for processing SMD components, which enable a high degree of miniaturization. The equipment includes, among other things, a stencil printer for applying solder paste, an SMD manual assembly station with microplacer, and a high-precision automatic assembly machine that also allows the production of complex assemblies in small batches. Furthermore, the assemblies are assembled, tested and integrated into the robotic systems in the electronics laboratory. In addition, various measuring devices are available for adjustment work and for repair purposes.

Mechanical workshop

Contact person: Daniel Pizzutilo

In our mechanical workshop we produce in the main prototypes and support-material (such as a sensor holder). Another task is the reparation and modification of our robot-systems. Those modifications include the adjustment of industrial products to special requirements.

The mechanical workshop possesses a solid basic configuration for mechanic treatment and a huge stock of standard parts and pre-products. For machining works we have a conventional milling machine (Wabeco F 1210 E high speed) and a screw machine in our equipment. They allow the prompt and precise manufacturing of the needed components. For the produce of smaller parts in batch fabrication we have a CNC milling machine (ISEL) available.

Whereas the manufacturing of prototypes, the repairing of robots and other smaller tasks are fulfilled in the workshop, jobs like batch fabrication of more complicated components are given to competent partners from industry and trade.

Rapid Prototyping Plotter

Contact person: Daniel Pizzutilo/ Roman Szczuka

Rapid Prototyping is a generative manufacturing process for the quick assembly of constructional elements from CAD Data. The printer uses the so-called “3D-Printing” process and is used for different purposes in the “Intelligent Structures for Mobile Robotic Systems” (iStruct) Project. The print head deposits a liquid plastic suspension layer by layer on a building table; UV-light hardens the construct to a solid.

Among others, mechanical demonstrators of spine, leg or foot concepts are made. Because of its precise print image, the printer is also used for sensor integration purposes. Generally, modern sensor elements are very small and have to be integrated very precisely into the surrounding structure.  For this purpose, the conventional assembly of construction parts is combined with the Rapid Prototyping process. In comparison to conventional manufacturing, complex structures can thus be produced quite easily, and different approaches can be promptly realized for comparing, evaluating, and optimizing.

Vacuum-Casting-Machine

Contact person: Felix Bernhard

The Vacuum-Casting-Machine is employed for the project “Intelligent Mobility (iMoby). With this machine, polyurethane casting components get degassed, mixed, and poured into their mold. The mold is built out of silicone or machine wax, depending on their application. Through the use of the so-called “Shape Deposition Manufacturing” process, functional structures of different hardenings can be created. This way, a structure may be provided with local material properties, for example, for making a special part of the structure adaptive or compliant. Actors and sensors can also be integrated into those structures.
