The robot uses one middle motor. This middle motor with the use of a few gear systems controls for different axsels. We have attached wheels on this axles so it is very easy to extend the robot construction for additional LEGO Mindstorms active attachments
What is the end result? - have the attached on the mission model. What is the mechanism the would make the robot hang on the mission model.
Remember the passive/active attachment separation that we are making at FLLCasts.com. This applies for all the attachments and in this Episode, we are looking at how to use a passive attachment.
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.
In this video we discuss the durability of the construction of LEGO robots and how do we make them more durable.
We calculate the number of rotatios when a gear system is involved. The driving wheel will have to do a number of rotations for the driven wheel to rotate to a desired number of degrees. In our specific case when the driven gear wheel is rotate to about 90 degrees the legs will lift the robot.
The task in this tutorial is to execute the program 10 times and to do it yourself. If you have your attachment then use it. If you have our attachment then use it. But execute the program 10 times and make sure that it works.
This one is very special- an attachment that could lock itself on purpose while working.
Present the details
In this video tutorial we accomplish the basketball mission from the FIRST LEGO League 2020 reply competition. We use the LEGO Education SPIKE Prime competition robot called Gazon. You will learn the principles of accomplishing a mission of two parts - put the ball in the basket and lift the basket.
In this video tutorial we look at Vertical Lift Attachments. The attachment, the root and the mission model are all build from LEGO MINDSTORMS Robot Inventor 51515 set. We've found that vertical lift attachments that could lift missions models vertically could be quite useful for FIRST LEGO League competitions. This attachment is one of the more complex attachments and some say it has an "eye opening" mechanism as you can learn so much from it. It uses gear wheels and two levers connected to those gear wheels to lift a part vertically.
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 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
This is a programming video tutorials. It uses LEGO Education Word Blocks which is the scratch version. We enter into details of how to accomplish missions in a tight spot, how to align the robot and how to make it repeatable.
