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.
What should you as a teacher know when the students are trying to achieve a program and robot attachment that could reproduce their behaviour 9 out of 10 times.
In this tutorial, we add another mission to our current program. This mission is - hanging the Gecko from the FIRST LEGO League Animal Allies.
Time to lift the robot. The first approach is by using the 40 teeth gear wheels that come with the LEGO Mindstorms EV3 and NXT robotics sets.
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.
How to align the wheels and how much should you push for this solution?
There were a few problems with the 40 teeth gears that we were using. Let's list some of them
Here is our solution for preventing torsion and bending of the LEGO Mindstorms EV3 axles.
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?
What should you do as a teacher when the students are calculating the gear ratios and number of needed rotations?
Building instructions for a robot for the World Robotics Olympiad Sputnik competition. This is the light version without the lift at the top.
"What is the light in the room?" - should it even matter. You can use one program for all lighting conditions by calibrating the color/light sensor of the LEGO Mindstorms EV3/NXT robots.
Building instructions for a LEGO Mindstorms Catapult Motor and Touch Sensor that are used for triggers for firing objects
These are building instructions for a LEGO Mindstorms EV3 demonstration model. In the tutorial, we are using it to demonstrate the working and relations of LEGO Gears.
This is a simple LEGO Gear System with a ration of 1:5. When the large wheel rotates 1 time the small wheel will rotate 5 times.
If you take a look at the videos for this attachment you will see a nice idea on taking the track and the ambulance. These two vehicles from the FIRST LEGO League 2013 competition had to be collected and returned back to base.
