  • Can we have three different EV3 robots?

    We see many teams using ONE EV3 and switching different attachments, this seems to be fine.
    However our team is building multiple robots using multiple EV3s and plan to switch them on/off the table during the 2 minutes.
    Is this allowed?

    Note too that your team has 2:30 minutes per round, not 2 minutes.

      It would be of great benefit to your team to thoroughly study the Challenge Guide before they go any further. As the Coach, It would be a good idea for you to study the Challenge Guide to confirm that your team understands all the rules. Please note that some of the rules interact with each other, causing implications that are not immediately obvious.

      It may also be of great value to ask a Coach from a veteran team from your area to visit your team, in person, to help clarify any misunderstandings of the rules.

        Welcome to the Forums, schucci!

        The first thing to say is that if you're willing to coach the kids on your team, you're a hero. This is a crazily complex game, and many of us have forgotten the stark terror of being a first year coach with a huge rule book and no clue.

        If there is any way possible, get to a scrimmage. When you do, seek out the veteran coaches. The big thing about FIRST programs is the incredible commitment to mentoring other teams, at every level. Older veteran teams get recognition if they can speak with your kids and help them, and it helps them develop even more as engineers and people. Most of the other coaches will be delighted to help you, and the few that don't want to help never seem to get very far in Lego League.

        Yes, one robot. One brain, and four motors. Period. You can bring a second one into the Robot Design room, but that's an irrelevant detail at this point. OTOH, one of the biggest functions of the Forums is for us to endlessly debate irrelevant details!

        Your kids will get to the point where the design of those attachments they place and remove during the match will be a very big thing.

          During a tournament, your team will normally play at least 3 robot matches. During each match, you can only bring one robot to the table. If your team really wants to, they can build multiple different robots, and use a different robot in each match. However, I do not recommend that approach.

          Many teams have multiple EV3s. Early in the season, the multiple EV3s may be built with different base robot designs. I think it is good for teams to experiment with different designs early in the season. However, I recommend that teams with multiple different robot designs eventually try to decide on one version they wish use at tournaments. Have the kids look at the different robot designs and list the advantages and disadvantages of each design. If you can, record information about that discussion, and bring up how your team decided on a base robot during the robot judging session.

          Once you have decided on a main robot design, try to build multiple identical versions of the base robot. Concentrate on using different attachments that work with the base robot design to solve different missions.

            I was working with a group of boys who could not agree on the robot design. Maybe every other week one of the lads would bring a different robot to the meeting. After a while I would shout out "Oh No, YARD!" when faced with Yet Another Robot Design. The tournament robot was picked at random. To coaches wishing more of the team members had their own robot kits, BEWARE WHAT YOU WISH FOR!!.
