In this video tutorial we accomplish the Cell Phone mission from the FIRST LEGO League robotics competition, season 2020-2021. The goal of the mission is to flip a phone. There were a couple of missions in the past with one important mission in 2017 that was very similar. It is a 10 out of 10 tutorial which means we accomplish the cell phone mission every time.
In this video tutorial we accomplish the Boccia mission from the FIRST LEGO League 2020 RePlay competition. We use LEGO Mindstorms Robot Inventor robot. In this mission we use an attachment that does three things in the same time - align, push one lever and drop a couple of boxes in a target. It is a complex attachment and it is worth the watch.
This video tutorial is about how to accomplish the Rowing Machine mission in the FIRST LEGO League 2021 RePlay robotics competition. The Rowing machine mission model consists of a wheel that should be pushed or pulled and will lift two other wheels, just like a real Rowing Machine. What you will get from this tutorial is an example of how to build a robot that is very precise. The attachment is simple, but the programming is more difficult. You must first align to a line, and then to a wall and then make a precise turn with the robot to accomplish the mission with our attachment.
This is a 10 out of 10 video tutorial that is different from the rest. We demonstrate how difficult it is to accomplish a mission and we use an attachment that is working 5 out of 10 times. Our goal with the video is to give everybody the understanding that taking your time to accomplish a mission is the right thing. Most of the 10 out of 10 tutorials at FLLCasts contain solutions and approaches that are working in a repeatable fashion. Not this one. See how difficult it is to accomplish a mission and that we also make mistakes.
Step Counter mission model is one of the more interesting mission models at the FIRST LEGO League 2020 RePlay competition. There is a locking mechanism that does not allow us to just push on the mission model to accomplish it, you must push it really slow and to do this 10 out of 10 times it is challenging.
This is a true 10 out of 10 video tutorial. The robot accomplishes the Weight Machine mission from the FIRST LEGO League 2021 RePlay competition every single time. The attachment demonstrate a mechanism that performs and is stable on every try
In this FIRST LEGO League video tutorial we accomplish the Step Counter mission from the FLL 2020 RePlay mission. The mission model is quite interesting as it can not be pushed fast and it can not be pushed slowly, because it will jam. The robot must push it with the right speed and this proves to be difficult.
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.
On every FIRST LEGO League competition and generally robotics competitions with LEGO robots, we build attachments to accomplish missions and we must accomplish the missions in a limited amount of time. Most of the time we can not accomplish the missions with a single attachment and we have to change attachments. This is where building robot attachments that are easy to remove really makes sense. In this tutorial we discuss some of the things that should be considered in the building Easy to Detach modules and attachments
This video tutorial is for the Tire Flip Mission from FIRST LEGO League 2020 RePlay robotics competition. Flip missions are always some of the most interesting and challenging. In this tutorial you would learn how to build an attachment and accomplish a mission that requires you to flip a part, like flipping a coin. Most of the complexity for this mission is in the attachment and not the programming, but this is also way it works perfectly, every single time.
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.
“Doing the same with less” can save time and space.
We start with the first mission - trying to build attachments that are small and tidy and the Gazon robot allows us to do so. With a few pictures you can see how the robot should be placed along with all the attachments
