“…For example, Arduino is an open source single-chip controller using script languages such as Java or C, or graphical/visual programming environments such as Scratch and Ardublock (Fernandes, Couceiro, Portugal, Machado Santos, & Rocha, 2015;López-Rodríguez & Cuesta, 2016). It is small, cheap, and easy to learn.…”

The robotics curriculum is one of the most common and popular curricula for stimulating students' interest in the science, technology, engineering, and mathematics (STEM) disciplines. The purpose of this study was to develop a robotics curriculum that highly integrates STEM and uses open software and hardware, and to test its effects on high school students' learning outcomes, interest, and perceptions of STEM. The study involved 82 Grade 10 students; divided into two groups, the experimental group experienced an integrated robotics STEM course, whereas the comparison group participated in a curriculum with commercial robotics. After a semester, the quantitative and qualitative data showed that the experimental group reported significantly more positive perceptions of integrated STEM, with strengthened knowledge, interest, and career orientation towards related fields. The findings of this study provide suggestions for STEM curriculum development.

“…Instead, a general method independent of wireless communication technology used was investigated. An effective monitoring software tool monitors different open system interconnection (OSI) layers through which communication is conveyed [40,41]. Protocols of the transport layer, UDP, and TCP are utilized by ROS for transmitting messages [24].…”

This paper presents various perspectives on designing and implementing a communication platform for a teleoperated mobile robot. The deployment of a communication network for a mobile robot and the integration of robot components in the developed communication platform are discussed in this article. A Wi-Fi-based communication network has been established, and to secure remote control over long distances, Internet-based communication via the 4G protocol has been launched using a virtual private network setup. Since an unstable network can damage the robot or the surrounding environment, an algorithm has been developed to monitor the state of the network connection through different protocols. The developed algorithm is able to detect network failure independently of the wireless communication technology used and notify the system of any disruptive communication. The robot's primary reactions to connection failure have been programmed to keep the robot under control until the communication with the control station is restored. Various experiments were carried out to validate the performance of the designed algorithm and statistical analysis was performed for each experiment. One of the main contributions of this study is the development of an algorithm for communication between the mobile robot and the control station based on both Wi-Fi and 4G, which is capable to keep the robot behavior safe and reliable in the presence of an unstable network or connection failure.

“…Such tough integration is very convenient for common software development workflow since ROS nodes are indifferent to source of data or commands. They could come through Wi-Fi, Ethernet, Bluetooth or even Zigbee networks 19 encapsulated in ROS topics. However, this encapsulation hides the data source information, therefore, there is no common way to determine whether topic is disconnected (data could not reach the destination point) or topic is simply empty (data is not sent at all).…”

In real world teleoperated tasks a robot connection with its operator is not always stable, so it is important to increase the robot autonomy. This paper focuses on increasing robot autonomy through autonomous return and charging station docking in a case of connection loss. We integrated the algorithm into real robot control system or PAL Robotics PMB-2 robot and experimentally demonstrated its good efficiency. The algorithm analyzes network failure through incoming TCP/IP packets, uses Simultaneous Localization and Mapping (SLAM) and path planning algorithms for autonomous return, and dock station plugin for the robot docking and recharging, which continues until the connection to teleoperator station is restored.
