“…Furthermore, most of the applications (9 out of 12) employed robotic tools from known educational material manufacturers, which may raise the cost of applications. Specifically, most of the collected applications employed LEGO WeDO kits [59], [60], [63], [65], Lego® Mindstorms® NXT robots [55], [61], Fischertechnik robotic kit sets [57], Bee-Bot [12], Aldebaran Robotics NAO torso [58] and Dash Robot [65], whereas 2 studies provided students with hardware electronics elements > REPLACE THIS LINE WITH YOUR MANUSCRIPT ID NUMBER (DOUBLE-CLICK HERE TO EDIT) < such as electric circuits kits and Arduino MEGA [56], [62] and only one did not mentioned the type of the robot [64]. Finally, despite the effectiveness demonstrated by the collected applications, some studies reported that there were issues in implementing Robotics in early education.…”
