The most stressed wheel in our system is the driven wheel. We've already fixed the problem with the driving wheel of the scissor mechanism and now it is time to look at the drive LEGO Mindstorms wheel.

Solution
We've added a beam connected to the axles of the driving and the driven wheel of the scissors mechanism. This prevents the whole robot construction from bending.
English
The most stressed wheel in our system is the driven wheel. So, we fixed this problem where we have a beam on both sides of the these two gears wheels. And now we need also a beam at this side of the gear wheel. It is mush more easier to bend the whole construction right here between the two large gear wheels. And this one is the last one - the driven one. And it's much more easier to bend the construction here than to do it right here where we have the small gear wheel because when we have the small gear wheel it will actually be the largest that is bending. But right here we have two 40 teeth gear wheels and they will bend. So, we must find a solution and our solution we've implemented it in our attachment. It's right here. How does it work? Let me just take an axle to show it. We have a beam that's connecting both of these large 40 teeth gear wheels and in this way the whole construction cannot bend here. And then we have this beam that's extended to the back of the attachment that assures that this small 8 teeth gear wheel will again not miss a teeth. And in this way we have the 3 wheels with beams on both sides.

FIRST LEGO League (FLL) 2016-2017 Animal Allies. Review of solutions with explanations
The course contains a number of sections with specific examples and tasks on how you could improve your FIRST LEGO League (FLL) robot game in order to achieve more points. It is designed mostly for after season teams that would like to prepare for next year, but could also work for teams that are currently working on their competition robots.

Extending gears drive (Coming soon)
One of the very common problems with the LEGO Mindstorms and LEGO Technic Gear wheels is then a tooth is skipped. In this video, I would like us to discuss this challenge and how do we solve it.
