Robotino XT – A mobile learning system with the Handling Assistant

Evolution of Robotino® XT – A mobile learning system with the Handling Assistant
Robotino XT is based on the Robotino mobile learning robot, which has already been established at universities and vocational schools.

The system is being extended with the addition of a compact version of the Bionic Handling Assistant.

The mobile robot can not only manoeuvre in cramped spaces – with twelve degrees of freedom in all, Robotino® XT can move flexibly and can extend its adaptive gripper with high precision.

 

 

 

A proven learning system
Thanks to its modular nature, Robotino® has proven is worth as a learning system of Festo Didactic. All its technical components are not only immediately comprehensible; their integrated system behaviour can also be learned.

Interest young people in technology

The student integrates and applies a great deal of technology, for example electric drive engineering and kinematics, sensor and control technology, image processing and programming techniques. Technical fundamentals can thus be conveyed in an intriguing, vivid manner. As a mobile robot, Robotino® has a highly motivating effect on young people.

Yielding  gripper arm
The flexibility of the gripper arm allows direct human-machine contact. In the event of a collision with the human operator, the system immediately yields, but with no modification to its desired overall dynamic behaviour.

No danger from direct contact

The assistant does not constitute a hazard even if the electronics or the control system should fail, since its structurally inherent yielding capability then comes to the fore.

Lightweight construction with additive manufacturing technologies

The yielding nature of the system is defined by its design, by the material chosen – polyamide rather than metal – and by its control and regulation technology. Its inherently flexible structure is stiffened to a specific degree by the pneumatic control system, so that a predefined spatial movement can be performed.

Winner of the German Future Award

Together with Fraunhofer IPA, Festo was awarded the German Future Prize for the yielding behaviour of the Bionic Handling Assistant and the resulting risk-free humanmachine contact.
