Virtual-reality-based remote-controlled mobile robot platform

Abstract

In this paper, a mobile robot system, which consists of a moving base and a built-in weapon platform, was developed. The base is controlled manually using a wireless joystick in which the remote hand weapon manipulates the built-in weapon platform. A stereo vision camera is mounted on the front plane of the built-in weapon platform. Real-time video of the battle zone is recorded by the stereo camera module and is simultaneously monitored on virtual reality glasses. The glasses are worn by the person who will control the built-in weapon. The remote hand weapon is also held by the same person, and the real-time motion directories of the hand weapon are transmitted to the main platform via user datagram protocol. The builtin weapon is fired when the remote user triggers the hand weapon. The weapon platform is locked to the target, regardless of the moving base of the mobile robot.

The effect of mobile and information technologies on the language development design of preschool children: a meta-analysis and meta-synthesis study

“…The rapid development of technology [Karakaya, et al 2017] and its involvement in educational processes brought with it the debate of mobile and its' effectiveness in learning and language development [Cavus, 2020]. Many researchers have tried to shed light on whether technology use is beneficial or harmful to the development of young children [McCarrick & Xiaoming, 2007].…”

“…It is noteworthy that there are studies testing the effects of language gains [Aral, 2006;Acar & Doğan, 2007;Karabulutlu, 2018;Özcan, 2018;Sung et al, 2016], and qualitative research examining the use of mobile and IT for the development of preschool children [İnci & Kandır, 2017;Kocaman-Karoğlu, 2016;Gündoğan, 2014;Şahin, 2006;Uluser-İnan, 2003, as cited by İnci & Kandır, 2017]. However, no metaanalysis and meta-synthesis study were found that bring all the available studies together and reports common shared findings.…”
