In the course of Intervitis, Interfructa, Hortitechnica, the Robot Makers GmbH and NIKO Maschinenbau presented a vineyard crawler for the first time, which is able to complete several tasks independently. In contrast to other systems on the market, the machine doesn’t use the high-precision RTK-GPS.
Technologies in the field of mobile machinery are advancing rapidly. Today there are already different systems, that help to simplify the use of such machines and make it more secure and efficient. And this is really necessary to meet the high requirements on the quality of work, with the simultaneously predominant pressure of time. In agriculture, for example, you will find assistance systems, that take over the steering of the vehicles with help of GPS and therefore help the driver to concentrate on the work of the implement. A long-term goal is also to develop vehicles that are able to do their work all autonomously. Efforts of this kind are described by the term “mobile automation”. Because there is also a big demand for similar systems in the field of pomiculture and viniculture the chair Agricultural System Technology of Technical University Dresden, the University of Applied Sciences Osnabrück and the University of Applied Sciences Geisenheim are developing the autonomous plantation robot elWObot with electric drives. In this project, the Robot Makers GmbH is responsible for the base control of the robot.
Through the use of (semi-)autonomous robot systems on land, water and in the air, the search and rescue of people in critical situations shall be greatly improved. This aim was settled by the “EU-FP7-Project” ICARUS. In this connection the multilateral control technology of the Robot Makers GmbH goes into action.
Together with the Swiss Company RUAG, the Robot Makers develop novel assistance functions in order to improve the safety of all-terrain vehicles. The expertise of the Robot Makers GmbH in that context is in particular the modelling of environment information and the control architecture.
In this project, the drive system control of a 50 kg tracked vehicle was realized with components by the company Robot Makers GmbH. A remote controlled vehicle of the type Digital Vanguard was equipped with a closed-loop controller for the tracks to allow the control via a PC-base interface.
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.

Development of a special camera system for the detection of water surfaces in the context of autonomous navigation of mobile robots. In this project, a demonstrator with embedded electronics and integrated image preprocessing was realized.
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.
