"I came to browse the Internet and build robots. And I am done browsing the Internet". Many different approaches, principles and directions to constructing robots with detailed building instructions and pictures.
It's a box! It's a robot! It's a box robot. Box robots are very popular on different robotics competitions involving LEGO Mindstorms like the FIRST LEGO League or World Robotics Olympiad. Let's start with a brief introduction and continue in the next videos with explanation on the features of the robot and why such robots are frequently used.
Here we start with a second box robot that we would like to build. It is in a way improvement to the first robot and we would take a look at its features.
The second construction of the series along with a comparison with the first construction. The new robot requires more parts, but has a few more advantages.
Five different robot chassis. This is the goal of the series. To present ideas for different design of the robots and especially the robot bases. If the base is stable and balanced, then in could easily be extended. Let's start with the most simple of the five.
In Episode 58 we introduced you to a LEGO Mindstorms EV3 Modular robot. In this tutorial, we show you how we reached that construction. We start from a construction found on the Internet and take you through the process of examining and improving it, till we reach a more stable and reliable robot.
In this lesson I would like to show you how to build a LEGO Mindstorms competition robot and tell you how we have designed the construction used in the videos so far. Surely it isn’t perfect, but it is a good start.
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
In this video tutorial we will show you three ways for making your robot stable on the field. We will present each one of them with their advantages and disadvantages - it's up to you to choose which one is the best for your case.
In this video tutorial we experiment with different ways of solving the sports mission for throwing the ball. We show seven different LEGO MIndstorms EV3 and NXT robot constructions and attachements. Most of the techniques could be applied for any mission involving throwing a ball or an object.
Let's try to integrate more of the things we have learned into a single attachment. One that could accumulate energy, conserve it and use it at the appropriate time. All this because of a Rubber Band and a Flywheel - and if you don't know what a flywheel is you should definitely watch this videos
With this series of videos we are looking at FIRST LEGO League 2013 Nature's Fury competition and we are building a robot for accomplishing some of the mission. It would be a tutorial with at least four parts and we are building a complex attachment that could catch, lift and release different parts with only one motor and rubber bands. Not one, not two, but three movements with only one motor.
Try to build the attachment following the instructions. Use it to actually solve a mission from any competition (like taking loops)
The Department of "throwing" is ruled by rubber bands. Impulsive power release in a short amount of time. In this video we are building an attachment that throws a ball and accomplishes the FIRST LEGO League 2012 bowling competition.
Football with robots could be quite fun. Football with LEGO Mindstorms robots is one of the popular categories for competitions with LEGO Mindstorms Robots.
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.
Build a rack and try to lift the robot with this rack.
Sometimes you could just throw a ball from base and solve a competition. Or at least many teams think so. In this video we would explore a very simple attachment for throwing balls from base. Can you use this for other missions? - we think so. Check out the video.
Build a robot base to use in the course. You can use the robot base provided by us or you can build one yourself.
Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.
Connect the attachment to the box robot and find the correct number of rotations of the middle motor that would bring the robot up and forward and would attach it to the mission model.
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.
Here is the task for adding a beam on both sides of every gear wheel in your attachment.
Experiment with changing the orientation and direction of gear wheels. Here are part of the tasks that you should complete before moving forward with the course.
The important task before the solution. If you haven't done it already, then attach a new axle at the front of the robot and extend the construction with gear wheels and axles to reach the two legs at the two sides of the robot.
Calculate the number of rotations you have to do with the motor to rotate the final small 8 teeth driving gear wheel to 1.25 rotations?
