Abstract

This report summarizes activities and conclusions from the first year (out of three) in the transfer project Autonomous evacuation. In the project a technical system is being developed, aimed at taking care of injured soldiers using unmanned, autonomous platforms. The activities the first year have mainly consisted in testing of existing, well-known algorithms to assess their applicability in a scenario where an injured, non-cooperative soldier is to be extracted from a point of injury. Two smaller field trials have been conducted from which the overarching conclusion is that existing algorithms can be used for solving several important sub-problem, e.g. analysis of the wounded soldier's body position, positioning of unmanned systems in the vicinity of the soldier, and generation of a 3D model of the scene at the point of injury. Work has also been initiated with collection of data to support development of a model for predicting vibration levels from geographical information. In the current absence of a representative, medium-heavy UGV, the work has focused on tests of data formats and looking at the literature as regards to analysis and representation of vibration data.
