Since July 1, 2017, a team headed by Arne Rönnau at the
FZI Research Center Information Technology has been researching a system with which robots can make independent
decisions in space missions. The outcomes of the intelliRISK project will enable robots to act more autonomously and flexibly on planetary
exploration missions. The aim of the project is to train robots in such a way that they can assess risks independently
and have the ability to consciously weigh up situations and make decisions. The project uses LAURON V, a walking
robot developed at the FZI, which is capable of moving safely even on rough terrain. LAURON V will serve as a test
and evaluation system for developments and is also to be expanded for planetary exploration missions.
Up to now, in planetary exploration missions, the respective mission teams decide on the actions of the robots used. As a basis for their decisions, the teams use data that is only available with greater delay or to a reduced extent. "In the current procedure, not all the information available to the robot is transferred to the mission teams and cannot therefore be taken into account in the decision-making process," says Arne Rönnau. The intelliRISK project is intended to close this gap in the future. The system can assess risks and influence situations independently based on the knowledge gained. Especially in cases where the success of the mission is more important than the potential damage to the hardware, the intelligence of the system is crucial. The intelliRISK system enables the robot to recognize, assess and consciously take risks in such situations - for example when it is confronted with a steep slope or a wide trench. At the beginning of the mission, the robot can still act cautiously, but later, towards the end of its lifetime, make decisions that are more courageous.
The project is of particular importance for Germany as a science location in the field of planetary research: "With the intelliRISK project, we are making an important contribution to increasing autonomy in the field of robotics," says Arne Rönnau. In addition to space travel, the system could also be used in other areas: "In future, risk awareness can also be used in industrial 4.0 applications to cooperate more safely with people and prevent accidents," says the robotics expert. But even in disaster control and recovery, the robot could put human welfare above its own in order to make rescue possible even in difficult situations.
The intelliRISK project is funded by the German Federal Ministry for Economic Affairs and Energy and supervised by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR).
Perceiving and understanding dangers is key in intelliRISK. The challenge lies not only in the detection of external dangers but also the wear and tear of the robot itself. Understanding how different dangers play together represents the first step towards a risk-intelligent robot.
A continuous flow of sensory information allows the robot to understand its surroundings. But understanding the gravity of any given situation, whether it be a collapsing ground or a broken joint, requires elaborate assessment. Knowing which risks count higher is crucial for a successful mission.
Complex decisionmaking is the final goal of intelliRISK. A robot should be capable of picking its own approaches to the mission. This means that it will take risks to reach its mission objective in time but also be able to inform any control team about its intentions.
