Think of an attachment that leaves the Gecko on the mission model. Don't use the robot attachment that we already have. Just the box robot and the gecko. Nothing should support the Gecko when it is hanged on the mission model.

Start close to the mission model. Move forward. Leave the Gecko. For leaving built an attachment. The simplest possible attachment that you could think of. 

Box Robot Two for LEGO Mindstorms Competitions

Building instructions for a competition robot following the "Box robot" principle. The robot is built with LEGO Mindstorms EV3 and could be used at FLL and WRO.


The first thing that you should do is think of an attachment that leaves the Gekko on the mission model without using the attachment that we already have. So, just remove this.

Like this. And we have the simple Box Robot. Now, the mission is to bring the Gekko from the base and to leave it on the mission model. Like this. And nothing should be supporting the weight of the animal. If you don't have the mission model, if you are using a box for climbing with the robot, you can try to put the Gekko there. Or if you have built your own mission model, again, if you don't have the Gekko, because I would assume that you don't have it, you can just have something with a loop and a small attachment and it will serve the same purpose. Leave something somewhere to hang. Like this. Try to do it on your own by building an attachment for the Box Robot that can just solve this mission where you reach you don't program the robot for reaching you start from here then do move forward and leave the Gekko on the mission model. Of course, don't forget to send us pictures and videos of the attachment that you've built so that we can see it, return some feedback and share it with the other users at
