Mobile learning flexibly extended 2 Robotino®XT is a mobile robot application that comprises both a learning system and a research object for future industrial applications. It is based on the Robotino®mobile learning robot developed by Festo Didactic. This system, which has already been established at universities and vocational schools, is being extended with the addition of a compact version of the Bionic Handling Assistant. Robotino®XT can thus not only manoeuvre in cramped spaces: with twelve degrees of freedom in all, this robot can move flexibly and can extend its adaptive gripper with high precision. Safe human-machine cooperation opens up new perspectives The flexibility of the gripper arm allows direct human-machine contact. Together with the mobility of Robotino®this opens up new forms of interaction between the human operator and technology, with high potential for extending the scope of human activity in many areas of life. Mobile robotics for learning and logistical tasks New perspectives with a yielding assistance system Excellent yielding behaviour Together with Fraunhofer IPA, Festo was awarded the German Future Prize in December 2010 for the yielding behaviour of the Bionic Handling Assistant and the resulting risk-free humanmachine contact. 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. In the event of a collision with the human operator, the system immediately yields, but with no modification to its desired overall dynamic behaviour. 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.
