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.
The challenge for this video is to program a menu that is controlled from the LEGO Mindstorms EV3 brick screen.
For the current specific example we need two parts - the diode and the controller. In this episode we would show you which part is the controller, which are the jumpers and finally we would choose a diode.
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.
The next step of lifting a robot to a mission model is to try to use a rack.
In this tutorial, we would drive the scissors mechanism and there are a number of rules that we must follow
Construct two legs for both sides of the robot. The task for this video is to attach this two legs on both sides and to build a system of gears and axles that power those legs.
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.
How great is the great attachment for lifting that we built in this course? How many times can it lift the robot without making an error? How great are your attachments and how could you test them? - the answer is simple. Just try 10 times and they should work at least 9 of them as our attachment is.
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.
The first part of making the robot move straight is to keep it oriented straight. While it moves it could make an error and turn slightly to the right and then the program should turn in back to the left to make its orientation straight. In this video tutorial, we would discuss how to implement a program to keep the robot orientation straight even when we are pushing or pulling it to either side and in the same time it has different wheels.
This video tutorial is about understanding the "magic". In this video tutorial, we would conduct an experiment and will look at how exactly does the integral part of the PID algorithm compensate for the error that the LEGO Mindstorms EV3 robot makes.
The bench mission was one of the most difficult we've encountered, especially when it comes to accomplishing the mission reliably. The goal of the mission is to push the bench down, lift part of it and leave 4 boxes at specific places. The whole concept of the mission is awesome. Here is how we did it:
This videos tutorials demonstrated the robot accuracy in 10 runs one after the other. 5 of them are with the robot moving slow and 5 are with the robot moving fast. See for your self what is the accuracy achieved only with the move blocks of the robot.
