The bench mission was a video tutorial that we recorded several times. It was really hard to get it 10 out of 10. The reason was the shear complexity of the mission. There are three things that should happen in this mission at once which was extremely difficult. What you will see in the tutorial is how this attachment behaves
This video tutorial had a different idea than what we recorded. We planned for a push/pull attachment as we've shown such attachments for LEGO Education SPIKE PRIME and LEGO MINDSTORMS EV3. However, the issues with LEGO MINDSTORMS Robot Inventor set 51515 is that we could not figure out an easy way to build a push pull attachment that meets our criteria for an attachment. Because of this we made a slight modification on the idea and it is again push/pull attachment but not moving in a line but in a circle - circular movement.
Similar to the tutorial for the LEGO Education SPIKE Prime this tutorial again accomplishes the cell phone mission. The mission is to flip the phone and is part of the FIRST LEGO League 2020 RePlay competition.
This FRIST LEGO League video tutorial is about he Boccia Share mission from FIRST LEGO League 2020 RePlay competition. In the tutorial we demonstrate how to push on a lever to release a mission model part - in this case a box. You have the choice before the competition to cooperate with the other team and to decide if you are going to do the blue or the red box.
In this video tutorial we look at an active attachment that uses gear wheel and the attachment is general enough to be suitable for reuse. This means that a lot of different missions could be accomplished with the same attachment. The goal of the attachment is to transfer power to a lever through a system of axles and gear wheels. It is interesting that we change the orientation of the gear wheels.
This is a 10 out of 10 tutorial where we demonstrate a reproducible completion of a shared mission. The mission is shared as both teams must agree about how they are completing the mission. The tutorials shows the robot approaching the FIRST LEGO League mission model. You will see how the robot pushes on the lever every time for a 10 out of 10 completion.
The bench mission was one of the most difficult we've encountered, especially when it comes to accomplishing the mission reliably. The goal of the mission is to push the bench down, lift part of it and leave 4 boxes at specific places. The whole concept of the mission is awesome. Here is how we did it:
In this FLL video tutorial we accomplish the step counter mission. We use a LEGO Mindstorms Robot Inventor robot. The idea of the mission is to control the robot in a very precise way so that it could slowly push on the mission model and accomplish it. In the tutorial we demonstrated exactly this slow push, but in a different way.
This video tutorial is about a detachable attachment. In various FIRST LEGO League competitions there are missions that could be accomplished with an attachment and when you accomplish the mission you must somehow leave the attachment along with the mission model. Probably as a support - most of the time it is as a support. But we've seen some pretty powerful concepts that include things like leaving a clock mechanism that will continue to work for 30 seconds accomplishing the mission.
10 out of 10 tutorials are about accomplishing missions in a reliable and repeatable way. In this video tutorials we accomplish the Step Counter mission 10 out of 10 times. We can push on the mission model, but if we push too hard we would lock it and there is no way back. So we use a slightly different approach. Check out the video to see how.
