Tracked Mobile Robot

This paper introduces a link-type tracked mobile robot developed for demining operations. The robot consists of three parts: a front frame, a rear frame, and a body. The front frame is connected to the rear frame by a rotational passive adaptation mechanism, which is a driving mechanism of the robot. This passive adaptation mechanism enables the proposed robot good adaptability to uneven terrain including stairs. The link structure gives rise to a small, simple, and energy efficient vehicle. In addition, the new demining system adaptable to the proposed tracked mobile robot is discussed on how to clear small anti-personnel mines with a non-explosive method. Both the motion of the demining rake and the design parameters of the demining unit are analyzed. Finally, a presentation follows on how the new demining system can unearth small anti-personnel mines with a non-explosive method.

Tracked Mobile Robot

The article renders the special features of the design of a tracked mobile robot (MR) for moving over inclined ferromagnetic surfaces while performing specified technological operations. There is conducted a synthesis of the functional structure and selective technological parameters (such as control coordinates) of the computerized monitoring and control system (CMCS) intended for use with this MR. Application of the CMCS with the proposed functional structure allows substantially increasing the accuracy of the MR monitoring and control, which in turn provides for a considerable enhancement in the quality and economic efficiency of the operations on processing of large ferromagnetic surfaces.

During the movement of the tractor on the uneven terrain, there are fluctuations that cause jumps of the working fluid in the hydraulic system and high dynamic loads. The solution to this problem is the use of an energy-saving hydraulic drive with a hydraulic accumulator and a system of aggregates this leads to increased efficiency and increased productivity of skidding grippers. A mathematical model of working processes with an energy-saving hydraulic drive is compiled.

Uneven Terrain

The influence of ground irregularities on the behavior of a wheeled mobile robot (WMR) navigating on uneven surfaces is addressed. The paper studies the vibratory movements induced on the body of the WMR, in order to analyze its ability for carrying out on-board tasks, and on the accuracy of the data collected by its external sensorial systems. The adhesion capability of the wheels of the WMR on this uneven terrain is also studied, since it conditions the braking, traction and steering performance. The method is applied to the WMR RAM.
