We are showing the first way we could position the motors on the robot construction. This seems to be challenging for many robot builders and that's why we are going to do it in a few different ways in the next few video tutorials from the series.
This second way of positioning the LEGO Mindstorms EV3 motors on the robot leaves more space for the Mindstorms brick and for attaching a third motor. We are experimenting and showing the advantages and disadvantages of this particular construction.
Now that we know how to make the robot move forward let's see we can make it move backward.
Let's move with the VEX EDR robot using its motors, the wheels and some RobotC programming. We devide the program in three parts - Connect the motors, program the controller and turning.
The comunication between the motors and the controller should be configured in the RobotC software. Each motor could be connected on a different port and the goal of the video is to show you how.
We are ready to build the first program for moving the robot forward and backward. We learn how to build simple programs for moving the program. But it is not that easy...downloading to the robot does not always result in the robot moving.
In the RobotC software we could make the robot wait for a couple of seconds by using the wait function. This will give the motors a chance to work and this will actually move the robot.
With this video tutorial, we start with Turns with the VEX EDR robot.
How does this construction of VEX EDR turn? It has two motors. Let's start with turning right
Spinning with the VEX EDR robot involves the use of both motors. The left and the right. Every robot with wheels could spin and this makes not exceptions.
The next important step when turning with a robot is to learn how to do an Arc turn.
Where is the math while turning? Is there any math involved? Should there be?
In this tutorial we would introduce you to the concept of loops using this VEX EDR Robot. As a final result we would have a program that makes the robot move in a square and not by repeating the same instructions for move and turn four different times.
To prepare the robot to move in a square and to use a loop in the program we would first make this VEX EDR robot move forward and turn, using a program developed with RobotC.
We start with the previous program where we made the robot move forward and turn. We continue in this tutorial with repeating the same RobotC instructions four times. Our goal is to make the robot move in a square.
The previous tutorial showed you how to copy/paste instructions in RobotC. The current video will introduce you to loops.
In this tutorial, we set the task of implementing another figure with the robot - a triangle.
The more advanced task is to more in a polygon. This would require calculating the degree of each of the turns and RobotC is a language in which you could implement this math calculation very easily.
In this tutorial, we are controlling the FTC Tetrix robot with the two sticks of the same GamePad. The left stick is for forward and backwards, while the right stick is for left and right.
