Abstract


The aim of this research work is to research and develop a system of a hand-like remote-controlled robotic arm. Devices of this design are currently in demand in many areas of human life, in particular during rescue operations. The described device must be able to hold an object of arbitrary shape using a gripper, has acceptable positioning and control accuracy. Such a device can be used to work in a harmful or hazardous environment, thereby minimizing the harmful effects on humans. The control system of such a device must provide a protocol for transferring data from the input device to the end handle of the manipulator to perform the corresponding movement. To start the development process, market analysis was conducted, in the process of which several similar products were identified and compared against each other and the system being developed. As a result of that analysis, comparison table was created listing the main features of the system being developed in comparison to existing solutions on the market, to check whether it will be competitive at the current market.

In this article, such system is proposed and later developed with the analysis of modern technical components and taking into account the accompanying scientific and technical research. In the course of the work, the analysis of existing technical solutions was carried out, the principles of operation of individual components were considered, and the process of developing the final system was described. As a processor device, it was decided to use the Arduino Uno and Arduino Nano microprocessor boards, which provide convenient tools for working with ATmega microprocessors with high performance and energy efficiency.

As a result of this work, functional, logical and electrical circuits were created and described, which were used to create a working prototype of the system, as well as a diagram of the model of the manipulator body, which was printed using a 3D printer. Using the created circuits, a working prototype of the described system was built, which was successfully tested, a demonstration of which is given in the work. The created one can be integrated as a subsystem into a larger-scale project.
