ROS user training

Due to the increasing importance of autonomous systems in everyday and safety-relevant applications, the open source middleware ROS (Robot Operating System) is becoming more and more important. In this context we offer application development and integration services as well as user training for beginners and advanced users.

The time period, the place of execution as well as the contents to be covered are agreed upon together with our client. However, it is very important to us to fulfill the teaching mission and to make the training as interactive as possible. For this reason, in addition to vivid simulations and professionally prepared teaching materials, we also rely on a number of demo devices, which we bring to the training to explain topics such as packages, nodes, services, action services, etc., as well as the integration in ROS.

GOALS

To learn about the functionality and advantages of ROS and ROS based systems and
in the scientific environment.

SCOPE

For 5 - 6 people in 2 - 5 days depending on the chosen content.

Methods of implementation

• Transparency / overview of the process at the beginning of the educational measure
• Comparison of the goals of the educational measure and the expectations of the participants/participants
• Appropriate alternation between input and interactive elements
• ->70% interactive methods, integrate practical work if possible
• Feedback to the participants, e.g. on concrete exercise examples
• Review of the seminar (flashlight round etc.)
• Real robot training on request.
