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
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 most stressed wheel in our system is the driven wheel. We've already fixed the problem with the driving wheel of the scissor mechanism and now it is time to look at the drive LEGO Mindstorms wheel.
Here is our solution for preventing torsion and bending of the LEGO Mindstorms EV3 axles.
Note for the teacher on making the construction more stable, more durable and using beams for this.
What should you do as a teacher when the students are calculating the gear ratios and number of needed rotations?
In the previous video, we found the correct answer for our task and it is 18.75, or is it?
In the course section for Advance Sensor Calibration we previously showed you how to find the minimum and maximum value for a single LEGO Mindstorms Color Sensor and to store this value in an array. The program was implemented with the EV3-G software. In this tutorial we are going to find the Min and Max for all the four sensors and to store all the 8 values in an array.
A common question is how to display arrays on the LEGO Mindstorms EV3 brick screen. Displaying values from an array is not different from any other display operation. In this tutorial, we would look at displaying two specific values. The minimum and the maximum for a specific sensor from the Advance Calibration Course Section
In this tutorial, we show you how to display all the values from an EV3-G array on the EV3 brick display. We are using an array Read Operation along with a loop. We are also detecting the loop counter and using it as an index to an array. It's basically the only viable way to do it. The process is commonly referred to as - "Iteration over an array" (although we still do not have an iterator in the programming language, we promise that one day we would do the super advance videos on "iteration" using the LEGO MINDSTORMS robots")
We will take a look at the EV3 motors and will go into details about them
With the EV3 Mindstorms set you receive three motors. Two are large and one is medium. These three motors could be used in different configurations and in this video we show how to use the motors on the second box robot for competitions that we build.
This is a course for beginners, but the tasks would be interesting and for more intermediate students. We do not expect any previous knowledge from you except for how to divide numbers and use a computer.
In part 1 of How to on Gears tutorial I introduced you to the basics of the gear systems. Now we are going to examinate gear systems with more than two gears and take a look at cascade gear systems.
Where should you lift the robot? Especially if you don`t have the mission model that we are using
