“…The conceptual model-based approach for modular complex system development can be regarded as the main contribution of Suri et al [2], which can be applied to industrial cyber-physical systems. These kinds of platforms are good for education, in specific tasks like teaching many theoretical algorithms [3][4][5][6]. Several authors have dedicated their work to finding optimal methods for controlling mobile robotic devices [7][8][9][10].…”

Due to the increased popularity of robotic systems and their more frequent application, some companies have opted to incorporate modular robotic systems in their assortment. The advantages of such systems are great flexibility in terms of combining components, relatively easy programmability, a wide range of functions that can be performed, the availability of components, as well as modularity in terms of functional and structural connectivity. The disadvantages are reflected by the fact that these systems are not optimized for a particular application. The precision and accuracy of such systems are substantially less than those of the system created exclusively for a particular application. Gaps and dead strokes of moving parts are very influential on the performance of functions and there is relatively little autonomy to such systems. The problem of mutual inarticulation of motors was introduced, and a solution was given to overcome these problems. The observations concerning the aforementioned problems have been explained and the most important features of this approach to robotic systems highlighted.

Lego Mindstorms education robot is an interactive robot because it can be used to design various kinds of robot applications. This robot can be used to design sorting robots before they are applied to real robots. Many sorting techniques are in the form of colorful objects, but only for one-time sorting. This research will design and implement a color sorting robot with 2 detection stages, namely the conveyor and the robot arm, the initial sorting is carried out by the conveyor for sorting color objects, the next sorting uses the robot arm. to move the selected color object to a place that matches the desired color. The results obtained in sorting color objects using 1 color sensor and Bluetooth for communication between the conveyor and the robot arm via Bluetooth works well where three objects in red, blue and green can be moved according to the desired color object.

“…Various studies were targeted at this topic already, aiming at basics of EV3 builds and programs (Rollins, 2014), (Bell, Kelly, 2017), (Harding, 2018), but also on more specific topics. Concerning the cooperation of EV3 with other platforms and coding environments, multiple articles were published about Arduino (Koch, 2020), android (Chen et al, 2018), Matlab Simulink (Klassner et al, 2012), (Lapusan et al, 2016), (Bevrnja et al, 2019), (Montes et al, 2021), Python (Crnokić et al, 2020), CNL based program synthesis system (Zhan, Hsiao, 2018), and MakeCode as an environment for programming EV3 (Voštinár, 2020). Multiple authors addressed use of EV3 as introduction of students to robotics (Ponce et al, 2019), (Montés et al, 2019), (Matyushchenko et al, 2020), trajectory control problems (A.…”

This article is focused on enhancement of HW/SW device by cooperation with a smartphone interface. The device was a programmable Lego Mindstorms Education EV3 set in the form of a robot designed to solve the Rubik’s Cube. The aim of the research was to replace the built-in color sensor with a camera that would allow the cube scanning process to be accelerated. Two approaches were chosen to meet the goal: the NXTcam camera, accessible as an accessory to expand the set, and the camera built into the smartphone. The use of NXTcam led to better scan time, but this result was prone to external influences. The camera on the smartphone sped up the scanning process to 57% of the original time. The impact of external factors on the outcome was significantly lower, compared to NXTcam. In the experiment, the cube solving process was observed in natural light, with addition distractive light source and in artificial light.
