In this cooperation project with the company Gross Funk, control technology for an autonomous stage vehicle was developed. This platform is optimized for the requirements of large arenas. Applications range from simple transportation tasks to complex choreographies with multiple systems. In that context the system offers a wide constructional flexibility.
The robot VIONA (Vehicle for Intelligent Off-road NAvigation) is an agile platform for applications in rough terrain. The vehicle has the dimensions of a small car and weighs about 700kg. The electric drive consists of four single wheel motors with 1.2kW power each. Front and rear axis can be steered separately. That way, complex driving manoeuvres like crab steering and double-Ackermann steering can be achieved.
Mechanics, electronics and control software have been realised by the Robot Makers GmbH. The rollout took place in October 2012 in the context of the “Sciences Night 2012” in Kaiserslautern.

Health is a central topic in animal farming, as product quality is directly linked to the well-being of the animals. Prophylactic measures can conveniently be achieved on any farm with animal care solutions by MK Nutztierhygiene. The latest generation of systems is driven by Robot Makers’ innovative technology. Precise sensing and intelligent control allows for an even more selective application to save disinfectants and water.
In this project, the arm of a bucket excavator was equipped with a computer-controllable interface. In the context of the project, a control system for hydraulic cylinders was developed. Furthermore, algorithms for the distributed control approaches were designed and optimized for a Volvo bucket excavator.
