The gap starts at 15 cm, and will increase by 5 cm each time your robot reaches the other side.<\/p>\n<h2>Props<\/h2>\n<p>Two desks (or other movable raised surfaces) and a soft floor! A large ruler should be on hand to set tables to specific distances.<\/p>\n<p style=\"text-align: center;\"><span style=\"color: #ff0000;\"><strong>Warning:<\/strong> Robots WILL hit the ground during this activity. Take steps to minimise damage.<\/span><\/p>\n<h2>Challenge Rules<\/h2>\n<ul>\n<li>There are no instructions or examples provided.<\/li>\n<li>No human assistance is allowed.<\/li>\n<li>Students operate with limited parts (a single MINDSTORMS kit) and time (as defined by teacher).<\/li>\n<li>All Robots must start ENTIRELY on one table.<\/li>\n<li>Robots must cross the gap to reach the other table, then\u00a0stop without falling off!<\/li>\n<li>Robots can use any method to cross the gap.<\/li>\n<li>Each student begins the exercise with a gap of 15 cm (approx. 6 inches).<\/li>\n<li>After each success, the student expands their gap by 5 cm (approx 2 inches).<\/li>\n<li>All students work on their own gap, making individual progress.<\/li>\n<\/ul>\n<h2>Design and Planning<\/h2>\n<p>Whilst students are not given instructions for this activity, a teacher can choose to pose the following questions to the help the design process:<\/p>\n<ul>\n<li>Where is the robot\u2019s tipping point?<\/li>\n<li>Will the robot always need to support both ends during a crossing?<\/li>\n<li>Will the robot always need at least one wheel in contact with a table?<\/li>\n<li>How can the robot be designed to handle increasing gaps?<\/li>\n<li>Will the\u00a0robot be all-in-one unit, or will it use a tool?<\/li>\n<\/ul>\n<h2>Activity<\/h2>\n<p>After providing the information above, let the students begin.\u00a0Teachers should display a countdown so students are aware of the remaining challenge time.<\/p>\n<p>An enthusiastic class will race to see the largest gap that can be crossed!<\/p>\n<p>I hope you find this useful.<\/p>\n<p>Regards,<br \/>\nAndrew Clark<\/p>\n<p><strong>\u201cProject Bucephalus\u201d Coach<br \/>\n<\/strong><a href=\"http:\/\/www.projectb.net.au\/\" target=\"_blank\" rel=\"noopener\">www.projectb.net.au<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Crossing the Gap is a free-form robotics activity that requires a minimal amount of setup.
