A removal system for Unmanned Ground Vehicles (UGVs) equipped with a modular robotic arm designed for hazardous and unstructured environments is presented. The system is based on commercially available solution that enables the manipulation of objects and removal of obstacles in complex terrains, such as disaster zones, battlefields, and industrial sites. The operational environment, teleoperation capabilities, and associated challenges are thoroughly addressed. Recent developments in All Terrain Vehicle-based unmanned platforms are discussed, demonstrating their suitability for rapid and versatile implementation in special-purpose missions. A model of an unmanned platform with an integrated robotic arm is proposed to enhance the existing range of medium-sized UGVs. The system configuration tailored for special-purpose missions is outlined, and kinematic parameters, along with stress tests, are provided to confirm its high adaptability to a diverse range of operational scenarios.

The article deals with the issue of verification of selected geometric characteristics of a special robot intended for the nuclear industry. The design of the robot is specific in that the robot works in both semi-automatic and manual mode. This leads to frequent collisions of some parts of the robot with fragmented equipment. Therefore, it was necessary to ensure the accuracy and repeatability of the robot after its production and during its operation. Verification of the parameters of the robot after one year of operation was carried out in the controlled zone of the nuclear power plant, which was specific due to the presence of ionizing radiation. The methodology, technique and method of verification had to be adapted to this. [ABSTRACT FROM AUTHOR]

The article deals with the design of a gripper for a manipulator. The use of a shape memory alloy actuator, which is excited by heating by means of an electric current, is proposed for driving the gripper jaws. Variant solutions of the gripper kinematics and the final design of the gripper arrangement are solved. A gripper kinematics simulation is created to find a suitable gripper geometry.

The article deals with the methodology of verification of mechanical and electronic torque gauges. Legislative metrological requirements are set for these gauges and the verification process for these types of gauges is also set. The working standard is used to verify two selected torque gauges and then the suitability of these gauges is assessed. Measurement uncertainties are identified to determine the reliability of the measurement process. [ABSTRACT FROM AUTHOR]
