The things that you will be able to do with your EV3 robot by the end of this course are:
Freely move your robot towards desired target;
Avoid obstacles on the path of your robot using sensors;
Follow lines of any shape;
Detecting and picking up objects of any kind;
This is a fun video with robots doing the Harlem Shake. We thought about posting the programs for the robots, but actually the whole Harlem Shake is so awkward that we decided not to do it :) Enjoy the video
An advanced but understandable description of how to program the mindstorm robot to move in a regular n-gon like pentagon, hexagon etc. (Yes, we know math). We have also included notes on the used formulas. A must see for each of you who would like to master the robot movements.
In the video we reach a conclusion. We have energy accumulated and to keep the system turning we need about 1J of energy each second to keep it turning.
Cable management is very important on each competition. Cables could get in the way of attachments, levers, different wheels and so on. Brick accessibility is also very important. Do not forget that the brick should be charged from time to time and that you should also be able to access the buttons.
We challenge you before we give you the theory: browse in the software and try to achieve the behavior in the video below.
A special fourth case for a turning with robots with two wheels.
Following the Advance Sensor Calibration course section, we found the min and max values detected by each sensor. Now it is time for the real deal of the calibration. Detect the current value from the sensor and find what is the percentage of this value for the range between min and max.
Following the Advanced Sensor Calibration course section, it is time to extract the logic for getting a calibrated value into a new block. This block will have an input and on this input, we give the port number. The block will return the calibrated value for this port number. We've built all the other blocks only because of this almost final video here.
The balance of the construction of the robot has a great influence on how it will move. This is especially true if you would like to move in a straight line. If the robot is slightly heavier on the right it will move to the right. Here we have two robots - a Five Minute robot and a Box Robot and we will discuss the differences in the constructions and why the box robot is much better than the Five Minute even though it is using the same parts.
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.
Given that the robot has two motors powering respectively the left side and the right side of the robot then when turning the robot is always turning in an arc. Depending on the turn this arc could be with a different size and radius.
Devi is a stubborn robot. No mater how many times you press the button, it will press the button last. It if you press again, it will press again. Sometimes it will rotate and speak, but will again press the button, and will continue pressing until the end of times.
This is an example of a robot for Sumo Robotics competitions. Specifically for RoboteX challenge. As most of the Sumo competitions have specific requirements for the robot size this one follows the 15cm x 15cm requirements.
Sumo competitions could be quite fun and interesting as the goal is to push the other robot outside of the ring.
This robot is part of the category of robots called animals. After following the building instructions you would have a frog that could jump. Of course, the jump depends on the surface and the friction between the robot and the ground... quite complex physics involved. But if you program it to move forward it will try to jump and it is your job to try to make it jump higher.
You could try to extend some of the legs, for example.
