Prototype Leanfit

In short time from the first design sketches to the prototype

For Daimler AG, we developed the design concept Leanfit, a robot system of the latest MRK technology. After the development, we were required to implement this complex system, consisting of gripper, control unit and control box as functioning prototype within a very short time. The entire structure was taken from the design phase and developed in SolidWorks. This resulted in 3D data sets for the different manufacturing processes.

Precise manufacturing

All aluminium parts were milled on a 5-axis machining center. The arm of the control unit is supplemented by a HPL plate as a hand rest, which accommodates the 3D joystick, a switch for confirmation and the emergency stop switch. These standard parts were additionally enclosed by 3D printing parts in order to increase the value and to produce an optically coherent overall system.

On-site installation

Before the final assembly of the prototype, a complete pre-assembly of the individual components took place at our company as a final check. All components were designed in such a way by us, that a fast assembly could be carried out on site at the costumer’s premises.


Improvements, made during the build-up, were included in the data records and all other prototypes could already be delivered in an optimized version.

Cost- effective solutions

The control box was printed out of polyamide in the rapid prototyping process. All 3D printing parts are individually modelled and combined to a component with a special connection system. This system significantly reduces the 3D printing costs for the costumer. The resulting component transitions and surfaces were afterwards sanded manually and vanished professionally.

"Graphical user interface (GUI)"

In computing, a graphical user interface (GUI) is a type of interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces which require commands to be typed on the keyboard.

The actions in a GUI are usually performed through direct manipulation of the graphical elements. As well as computers, GUIs can be found in hand-held devices such as MP3 players, portable media players, gaming devices and smaller household, office and industry equipment.
