Below you could find buildingin instructions for Box Robot Two and a few of its verions with little modifications. Which robot you would use really depends on you and your requirements for the missions and the field.
After the first box robot course and its enormous success, we decided to build a second box robot. This time with fewer parts and with only three motors. The EV3 set comes with one medium motor and this robot will be easier for new teams. It is also lighter and more simple. Take the course and learn the ideas that we have in mind in simplifying a robot. Use this course with students and try to experiment to make the attachments and construction even simpler.
