Article
The revolution of technologically advanced vehicles with a high level of automation involves a profound transformation. The focus of most research in this area has been on the use of travel time for different use cases. Sleeping is one of the most time-consuming activities in everyone's life; therefore, this has been described as one of the most de...

Conference Paper
The implementation of robotics in schools is inevitable in the years to come. Currently, this integration is not feasible for all schools (especially public ones) due to the high economic cost, which in most cases offer a closed system (both hardware and software) which limits the robot to a single educational level. The educational innovation proj...
Conference Paper
Educational robotics has come to the classrooms and is here to stay. STEAM (Science, Technology, Engineering, Arts and Mathematics) learning has put the use of robots in classrooms in vogue, though these are mostly closed products and at a high price.
