Mecanum-Kinematics and Teach&Repeat-Technology for Stage Wagon mecanum drive

To realize innovative show concepts, heavy stage structures and stage prop needs to be moved reliably and precisely upon the stage. A few years ago these kind of transformations had to be done while the curtain is closed, because many staff members were needed. With the help of the stage wagon built by Gross Funk GmbH, it became possible to perfom transformations while the curtain is opened and with the help of the Teach&Playback-Technology, with a high repeat accuracy, too. This concept was further improved and therefore equipped with a mecanum-drive to enable maneuvrability in an other dimension.

Base control of the modular plantation robot elWObot

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.

Control technology for mobile stage equipment

Aktivieren Sie JavaScript um das Video zu sehen.

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.

Off-road Platform VIONA

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.
