To familiarize educators and users of the TekTrain platform with its features and functions, a detailed user manual has been created. This accompanying material, entitled “Designing robotic applications with the TekTrain platform” is available on the internet at the website http://www.tektrain.web.auth.gr/documentation. The manual consists of three main sections, with written instructions and snapshots of the platform. The first section provides general information and instructions on how to connect and disconnect, customize the environment and its main screens, such as profile, exercise page, and reference application page. Also, this section presents the graphical programming environment with its five distinct parts (control box, command line, drawing canvas, programmer tools, trash can) and explains each graphical command, and its parameters, separately. The second section of the manual is addressed to the user-teacher and presents the functionality offered by the TekTrain platform to each registered as a Teacher, such as creating, editing, and deleting an exercise or a student, assigning an exercise or robot to a student, the scoring a solution and creating a progress report. Finally, the third section is addressed to the user-student and presents the functionality offered by the TekTrain platform to each registered student, such as viewing and solving an exercise, submitting an exercise to be solved, viewing performance awards, and viewing the assigned robot.
