The Task 5.4 called “Testing of RESCUE MIMS on-board robotic platforms and drones” is an activity lead between Month 10 and Month 30 in the Project Search & Rescue. The main scope of T5.4 is to test the robotic platform provided by DFKI with its sensors (Cameras and LIDAR), the Obstacle Detection System (ODS) provided by THALIT and the field chemical tool (RESCUE MIMS) provided by the NTUA together with the drone provided by UHasselt. In order to share all the possible interface from Telecom, Power, Physical and Logical point of view a dedicated Interface Control Document has been developed in order to align all partners on the mutual interfaces. Within the Task 5.4 some specific tests are foreseen, for example the ODS algorithm will be tested with some images provided by the end users, the robot will be tested with a dedicated test and the RESCUE-MIMS will be tested in lab-scale experiments The related deliverables foreseen in the Task 5.4 are two: the D5.4 “Testing of RESCUE MIMS on-board robotic platforms and drones” (this document) where the topic is introduced as per status of the project and the D5.8 “Testing of RESCUE MIMS on-board robotic platforms and drones, V2” that is the revision 02 of the D5.4 with the possibility to finalize all paragraphs not ready at the moment of the D5.4 release. The main objectives and outcomes of the D5.8 “Testing of RESCUE MIMS on-board robotic platforms and drones, V2” are the description of the platform robot with its sensors (Cameras and LIDAR), the Obstacle Detection System (ODS), the field chemical tool (RESCUE MIMS) and the drone; in particular it is described the integration and the interfaces between all these components following the activities of Task 5.4. Moreover, it is introduced the testing procedures of the whole technological platform and at the end the test reports. The milestone submission of D5.8 is at the end of Month 30, moreover the Use Case where all the components will be tested together is the number 4, named “Forest fire expanded and threat to industrial zone (Corinthia, Greece)” that is foreseen in November 2022.
