FiFi Assistance System Reacting to Hand Movements An Intralogistic Vehicle Controlled by Gestures in a Contact-free Manner For internal movement of goods, researchers at Karls - ruhe Institute of Technology (KIT) have developed a vehicle that can be controlled by natural gestures: ”FiFi“ scans its environment by means of a 3D camera, follows its user like a well-behaved dog, recognizes gestures, and executes the relevant commands. By facilitating the movement of goods, FiFi makes pro - cesses more efcient and relieves employees. In many companies, goods and material are still handled and transported manually. The FiFi assistance system was designed by researchers at KIT’s Institute for Materials Hand - ling and Logistics (Institut für Fördertechnik und Logistik- systeme – IFL) for intralogistic processes found in e.g., vehi - cle spare parts high-bay racking, online trading of consumer goods, libraries, and internal goods delivery. “FiFi is a user interface that is much more intuitive and natural than con - ventional conveying systems,” Head of Institute Kai Furmans explains. “Indeed, it is our intention to make technology manageable.” FiFi is an automated guided vehicle (AGV) with electrical drive and camera system. Without the user getting into direct contact, it can be controlled by natural gestures and is thus superior to conventional solutions. This is how the new assistance system works: The built-in camera generates a 3D image of the environment. From this, a skeleton of the user Department of Mechanical Engineering Institute for Material Handling and Logistics (IFL) www.kit.edu KIT – University of the State of Baden-Wuerttemberg and National Research Center of the Helmholtz Association and the user’s hands is generated via a 3D image processing algorithm. By means of a vocabulary of gestures, FiFi then interprets the respective skeletal changes and sends the rele - vant commands to the hoisting and traveling units. Waving the right hand three times, the user logs on to FiFi and is recognized while other perso

2 ns are ignored imme - diately. As soon a
ns are ignored imme - diately. As soon as the user logs out again by waving the left hand three times, FiFi is ready for login by another user. Depending on the specic needs, users can choose between different operating modes: In the shunting mode, they con - trol FiFi by moving their outstretched hands. Moving the arm up and down, they can operate the tray hoisting mechanism, which enables ergonomic lifting of the transported goods. In the follow mode, the users have both hands free for other tasks while FiFi follows their movements. Finally, when the user points to a line on the oor, the vehicle moves indepen - dently along this line to the next position. FiFi can be controlled much more intuitively than conventi - onal intralogistic transport vehicles. Operating safety is en - sured as well: To avoid collisions with persons or objects, FiFi is provided with a safety laser scanner whose protective eld is adapted dynamically to the travel speed. When a person or an object comes into that eld, the system stops imme - diately. The assistance system facilitates load transportation, makes processes more efcient, and relieves employees. FiFi hence is expected to contribute to designing age-appropriate workplaces, which in view of demographic trends is gaining in importance. Headed by Andreas Trenkle, the KIT researchers so far have realized two versions of FiFi: A smaller vehicle with a base area of 50 x 50 cm enables transportation of loads of up to 30 kg. A larger vehicle developed with the industry partner Bär Automation GmbH can pull a cart and transport loads of up to 300 kg. In principle, FiFi is suitable for various intralogistic processes, from handling of incoming goods to picking and packing through to goods issuing. The pilot run already has been suc - cessful. Together with Bär Automation, the KIT researchers have optimized the system for various uses and currently run tests in several elds of industry.
