This paper presents method of selection of configuration for manipulators of portable robots for special purposes. On the example of the portable PIAP Patrol robot, the analysis of tasks and related requirements for the functionality of the manipulator was presented. With the use of multi-criteria optimization tools, the selection of the manipulator configuration parameters was carried out, which leads to the maximization of selected working capacities while ensuring that the imposed requirements and mass and kinematic limitations are met. The results of simulation tests were presented and the scope of further work was outlined.

The construction of mobile robot manipulators for special applications must be optimized to achieve the required working capacity while maintaining a low mass. In the literature on the optimization of manipulator structures, the authors most often take into account the most unfavorable load case in their calculations or take into account several distinguished load cases resulting from the static or dynamic of the loaded manipulator. To optimize the design of a teleoperated robot manipulator, which during operation is exposed to contact with obstacles in an unstructured environment, the load analysis must be carried out in many aspects. The results of such analysis are used to select manipulator elements, e.g. drives, and to determine the loads for the design of the load-bearing structure and its optimization. The determined loads can be used to perform topological optimization of components of manipulators to minimize the mass while maintaining strength adapted to the operating conditions. Preliminary work on the preparation of a method for selecting such loads is presented.

The article concerns the most important issues of designing an unmanned vehicle for the implementation of observation tasks in the protection of the perimeter of the state border. An analysis of the terrain conditions necessary for the unmanned vehicle to overcome and a description of the key components of the HUNTeR vehicle responsible for the ability to work in such conditions was presented. Also included were tests verifying the basic assumptions of the project in the field of operation at the maximum speed of travel.

This paper presents a method for designing manipulators for man-portable UGVs (Unmanned Ground Vehicles), intended for military and counter-terrorism applications. The approach involves selecting manipulator parameters based on requirements for capabilities and a database of available components. The authors identified a gap in the existing literature regarding load definition, particularly for small robot manipulators used in Explosive Ordnance Disposal (EOD) tasks. To address this, a method is proposed consisting of three main stages: In the first stage, manipulator drives and geometric parameters are selected. In the second stage, a detailed load analysis is performed. A distinctive feature of the proposed method is the use of optimization techniques to determine the maximum possible loads during load case definition. In the final stage, topological optimization of the components is carried out. The method was validated using a selected manipulator joint of a portable robot designed for EOD tasks.
