In this tutorial of the series we would get into more details on how the flywheel works, what's its purpose and how the whole attachment is triggered with the first rubber band.
Робота Икозейтър е конструиран с идеята да може лесно да се променя зъбната му предавка. На видеото може да наблюдавате един начин за смяна на предавката му, като се извади гредата и се разменят зъбните колела на мотора и верижното колело. За предавки с различен размер зъбни колела се иска промяна в дължината на веригата или броя зъбни колела.
"The devil is in the details". We are improving the Rubber band attachment with a Flywheel by introducing a few small, but important modifications that make the whole robot attachment more stable and reliable. With the conclusion of the series this attachment could be used as a basis for some very interesting STEM demonstrations on energy accumulation and conservation.
The next step of lifting a robot to a mission model is to try to use a rack.
Many teams have followed the same idea as the ELM team. To build a LEGO Mindstorms attachment for the robot and to lift the truck very lightly. In this way they could more the truck and place it in the special region. See what the ELM idea was.
We've already build a number of resources for lifting at FLLCasts.com. But at the end of this course we would have a robot that lifts itself and hangs on the mission model.
Go to the missions model. Do the missions. You can then continue to the next mission or wait a few seconds at this FIRST LEGO League 2015 Trash Trek mission model and receive a few more points. Isn't it interesting. The ELM team has build a LEGO Mindstorms attachment for this robot. Let's see how it works.
Build a rack and try to lift the robot with this rack.
We are working on the World Robotics Olympiad (WRO) 2013 competition and its elementary part. The series will introduce three different concepts and this would be Arrays, Menus and Counting different lines. In the video you will see the robot working as it is in the final stage.
A robot that contains balls and releases them. It counts how many balls to release depending on the "treasures" it has hunted on the field. This is part of the World Robotics Olympiad 2015 Elementary challenge.
Part four of the Catapult series is again about loading the catapult automatically but this time using EV3 brick, motor and sensor. We use a gear system with a medium complexity along with a "standard clutch" available in the LEGO Mindstorms EV3 kits. As a result, at the end of the video, the Catapult loads and fires automatically.
Moving in a grid of objects. That's the large challenge of the World Robotics Olympiad 2015 Junior-High 2015. In this video we would build a robot that can collect the boxes (treasures). The robot would also be able to move around the treasures.
The third part of the series the goal is to extend the robot attachment so that we could solve the second part of the FIRST LEGO League World Class mission challenge - to take the loop.
The attachment is now so advanced that we can do two tasks at once with it in order to solve the FIRST LEGO League 2014 World Class Search Engine Mission.
How can you accumulate some energy in an LEGO Mindstorms EV3 construction an use this energy at a later moment? How does a Flywheel work, why is it important and what is the purpose? What is energy, inertial moment and angular velocity. These are just some of the questions we would answer in this series on Physics and LEGO Mindstorms.
(LEGO humans of course, not real humans :) ). Working on World Robotics Olympiad 2014 elementary challenge. Collecting modules, bringing them together and lifting them. A very funny and interesting competition that we would explore in this and the next video tutorials from the series
Как да сменим посоката на греда от хоризонтална във вертикална.
Starting with the World Robotics Olympiad 2014 Junior-High challenge we first catch the object on our path. We discuss a good mechanism for catching and lifting balls that can do two movements with one motor.
In this second video lesson on catapults we improve the stability of the base of the robot. An important feature of the new base is that it is not bending. Use the same principle in all of your constructions to achieve better, stronger robots.
Based on your feedback we have decided to show you the live process of building a complex LEGO Mindstorms Competition robot without having the whole robot ready yet. We are continuing from part 1 where we finished part of the 'front' of the robot and we arrived at a construction that we didn`t like and would fix in this video lesson.
In the video we improve on the robotics mechanism for pushing the different blocks out of the robot container. We continue from the previous video.
In this video we look at the robotics mechanism for dropping the different blocks into the different region on the World Robotics Olympiad 2013 field.
The final way for lifting our box robot is by using a scissors mechanism. In this Episode, we would discuss the benefits and advantages of this mechanism.
Ще построим лесния робот EasyBot и ще ви обясним как да следвате инструкции.
In this tutorial, we would drive the scissors mechanism and there are a number of rules that we must follow
We continue from part 4 where we made a controlled experiment to transfer power from a Mindstorms motor to the rear wheels. The construction was too complex and inefficient and in this video lesson we are improving it by lowering the differential and removing all gear wheels from this LEGO Mindstorms EV3 Competition robot.
Extend the previously build attachment for the FIRST LEGO League (FLL) Nature's Fury competition so that we can move the Truck and Ambulance up and down.
