Since 1991

Learn more about ROS

The engineer Hansgeorg Röbe-Oltmanns has founded the company ROS in 1991 in order to support industrial companies with intelligent electronic solutions regarding stepping motors and stepping motor controllers.

The previous three very successful stepping motor controllers STEPPER1, STEPPER8 and Ministep did a reliable job in the recent years and led to significant cost reductions for our customers. Because of their high quality they were part of some world leading custom systems.

Project support
“at every turn”

In direct dialogue, we accompany your project “every step of the way” from problem definition to testing and certification to successful productive use. We rely on reliable hardware that is still available after many years. This way you can be sure that reliable productive use is sustainably ensured.

On this basis, ROS develops, for example, prototypes and series devices for industrial solutions in which the innovative controllers of the SmartStep family are used. These prototypes can be used for testing with the help of our PSC (Personal Stepper Controller) software. You can integrate the supplied DLLs into your own programs.

Our specialty: "Tailor-made controller systems"
You have to develop a device and you need a special controller? This is our specialty! For smaller quantities, this can be realized very quickly by using our standard stepping motor controllers and possibly some parts usual in trade.

For larger quantities, usually an individual design is necessary. In many cases the electronic components should be installed on a single circuit board. This is convenient, saves costs and the wiring is much easier.

You need power supplies, control panels, displays, interfaces, sensor connections, and perhaps one or more stepping motors? We install these components on a circuit board for you according to your specifications (for example environmental requirements and dimensions).

Step-by-step through all nessesary tests
On request we lead your device through all necessary tests, such as safety tests and electromagnetic compatibility tests (EMC). We work closely together with our longstanding partners in the test laboratories. Our experience in the design and procurement of electronic components assures a prompt delivery and long-term availability. Our discreet and professional approach of course includes an appropriate confidentiality agreement.
Stepping motor controllers of the latest generation
ROS proudly presents the latest generation of stepping motor controllers: SmartStep-1K-BP, SmartStep-1K-LP/HP and SmartStep-3K-LP/HP with extensive accessories.

Example: SmartStep-3K-LP


On these intelligent controllers of the latest generation, control unit and power unit are on the same circuit board. Stepper-1K-BP can be mounted directly on the back of the stepping motor (Backpack). With SmartStep-3K-LP / HP up to 3 stepping motors can be connected.

Personal Stepper Controller (PSC)
The reliable, sophisticated and permanently improved controller software application PSC (Personal Stepper Controller) is very easy and intuitive to use.
