Second active pinless attachment for the robot construction. It is placed in the top/right corner of the robot and includes an interesting gear system for transferring the power. The attachment is suitable for complete rotations.
Where should you lift the robot? Especially if you don`t have the mission model that we are using
The FIRST LEGO League competition is similar each year. With a little experience you could accomplish most of mission. The goal of this episode is to introduce you to the course, its purpose and approach.
The next step of lifting a robot to a mission model is to try to use a rack.
What is allowed and what is not when building without instructions.
Our next robot is called CastorBot, because of the castor ball.
We just had some enormous amount of fun with building and using a catapult/trebuchet. Yes they are quite different, but the result achieved in the lesson is something in the middle. Learn how to fire elements using the LEGO Mindstorms EV3 or NXT robotics set. Challange yourself, your team or your students to build it and fire elements as far and as accurate as possible.
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.
In this robotics tutorial, we present a solution to extending a VEX IQ attachment to handle two hex balls at a time
This WRO robot is designed to collect a lot of ping pong balls in its container. It's built with LEGO Mindstorms EV3 45544 and 45560 sets. These are the LEGO Educational sets. The robot has two chains that collect the balls and push them into the container attachment. This is one of the larges robots we've uploaded at FLLCasts yet. You could learn a lot by following the building instructions and paying attention to the details of how this robot is built. All the alignment, all the connections. Really beautiful.
Third part of the LEGO Mindstorms BidDaddy Competition Robot.
DIfferent wheels and tires will result in different behaviour of the robot. That is actually pretty common sense. The real question is what is the influence. Would the robot make smaller deviations if it has smaller wheels or it will make larger deviations? The tires could also be quite dirty or brand new. Or the wheels could be attached in different ways.
This robot extends the Tetrix Box Robot chassis for FTC competitions with an additional arm. The arm could be used for lifting and placing objects and could be quite useful.
There is a special rubber band at the end of the arm, because there are not enough parts in the Tetrix set and we had to use a rubber band. But the principle of the arm is interesting, useful and you should be familiar with it - the arm keeps the motors always in the right orientation.
This is a simple robot, variation of the Earl bot using treads. You can use the attachment to kick balls sideways. The robot is useful in STEM classes where students have to construct robots quickly.
This is a Camel-like robot. We demonstrate an interesting use of gears to make the Camel walk. Fun and entertaining way to learn how to transform motion.
Instructions for building module 4 version 1 of the Ugbroid - rear wheels.
Building instructions for a LEGO EV3 Robo-tank. The construction is incredibly simple, with an upright Brick, which makes it perfectly suitable for lessons with students.
Probably the largest multi-purpose FLL attachment at FLLCasts. These attached is doing a number of missions at once. 4 of them. You attach it to the robot and start the program. The robot moves and accomplishes a number of missions using only this attachment. At it also has a lot of parts. It is quite large and you can not build it from a single set. But that's ok because you are preparing for a competition, right?
In this course, we would like to introduce you to multi-purpose attachments. These are attachments designed to accomplish a number of missions when the robot goes out of the base in the FIRST LEGO League competitions.
You've all seen them. They are kind of large, powered by a few motors and sometimes use rubber bands, levers and other mechanisms.
Use the course as a preseason preparation and try to solve the tasks to prepare for next year competition. Even if you don't have the field, build the attachments and follow the tasks to inspect their behaviour. Modify them as needed when said.
This is the first draft of the course including only the attachments in different sections. If you are interested in learning more please enrol in the course and in the next few weeks we would try to record the video tutorials.
Instructions for building a LEGO truck. We use a medium motor for steering and a large motor for driving one of the rear wheels.
