With tutorials, courses and building instructions with gears you could learn how to use Gear Wheels, Warm Gears and Racks. Everything spins. With a few gear wheels you could make it spin faster or harder. Check out the examples of different constructions, robots and attachments that make use of gear wheels.
This is a 10 out of 10 video tutorial for the FIRST LEGO League 2020 RePLAY robotics competition and the Treadmill mission. We build a robot with consistent behavior that is able to achieve the mission every time
This 10 out of 10 tutorial is a complete uncut recording and it shows how the Chain Monster box robot accomplishes 5 missions in a single run and it does this 10 out of 10 times. It is from the FIRST LEGO League 2022-2023 robotics competition.
Accuracy and consistency is the topic of this tutorial, as all 10 out of 10 tutorials are at FLLCasts. We use a robot build only from LEGO Mindstorms Robot Inventor parts and we accomplish the mission 10 out of 10 times. You will see how we use an active gear attachment to catch the wheel and pull it to the black circle, which accomplishes the mission
As we are already off the season we decided to look back at the competition. First, we will take a look at the working solution for FIRST LEGO League 2017 Manhole Cover. This was generally accepted as one of the most difficult missions during the competition. We've built a single attachment to accomplish it.
(we are releasing the video without explanations and will add the explanations later)
This 10 out of 10 tutorials is about consistency and reliability of the robot when accomplishing 5 missions in a row. We explore how we move between mission models. The programming is in the previous tutorial, here we look and discuss the behaviour of the robot
In this video tutorial we accomplish 3 missions from FIRST LEGO League 2022-2023 SUPER POWERED competition and we do it 10 out of 10 times. We successfully deliver the three object to 2 different places on the field. It is interesting that we have to carry the dinosaur toy from one side of the field to the other.
This is a 10 out of 10 tutorial for a 3 missions run. The robot goes out of base and accomplishes 3 missions in a single run. It demonstrates the consistency and reliability of the robot and its program that uses sensors.
This is a 10 out of 10 video tutorial demonstrating the consistency and reliability of the Kriket robot when accomplishing the FIRST LEGO League 2022 missions called Wind Turbine, Television and Rechargeable Battery.
This is the 10 out of 10 version of executing 3 missions in a single run. It worked like a charm! 10 times. We push and collect energy units for the FIRST LEGO League 2022-2023 SUPERPOWERED Challenge competition.
This video tutorial is part of the series on how to make your robot 100% precise and accurate. We accomplish the Emergency Walk mission 10 out of 10 times. The attachment works. Every time the attachment is started in successfully accomplishes the mission and this is one of the most difficult missions on FIRST LEGO League competitions ever.
This is a 10 out of 10 tutorial for a complex robot attachment that does a precise drop and is auto-correcting at the same time. It has decent consistency and reliability. We drop cargo onto the train and use a LEGO Education SPIKE Prime robot for this FIRST LEGO League 2021-2022 competition.
This is a recording of a completely perfect, 10 out of 10 accomplishment of a two-part mission - Train tracks, from the FIRST LEGO League 2021-2022 Cargo Connect competition. Due to the proper use of motion and color/light sensors, the robot is 100% consistent and reliable for a non-trivial mission. Even when the robot makes a mistake, it auto-corrects and compensates for this mistake.
This is a 10 out of 10 tutorial, demonstrating the consistency and reliability of the active attachment for switching the engine in this mission. The power is transferred through a system of gear wheels to a lever at the end. We presume that the robot is already positioned.
In this video tutorial we accomplish the Basketball mission 10 out of 10 times. We use one of the more complex attachments for the FIRST LEGO League 2020 RePlay competition. You will see an learn how to successfully and consistently complete a mission that requires the robot to put a ball into a basket and lift the basket, or lift the basket and put the ball into it.
This is a 10 out of 10 tutorial demonstrating the accuracy of an active gear attachment that accomplishes the Treadmill mission from the FIRST LEGO League 2020 RePlay competition. When the robot is well aligned to the line before that it is easy for the robot to accomplish the mission. You will see how we make use of the friction of the wheel to rotate the mission model.
This is a 10 out of 10 tutorial demonstrating the accuracy of a Flip Attachment for the FIRST LEGO League 2020 Cell Phone Mission. The flip attachment flips a phone. Moves forward and flip it. This is a tricky business. It might not work. The trick is to approach the mission model from the right angle. In the tutorial you will see a demonstration and will learn how such a mission could be accomplished accurately with a LEGO Mindstorms Robot Inventor robot and attachment with gear wheels.
