oracid posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Do you know this, http://www.mindsensors.com/ev3-and-nxt/21-multiplexer-for-nxtev3-motors You may have 12 Lego servos with only one EV3. -
The company I work for (Sioux) is one of the main sponsors of Tech United, the leading World Champion in robot soccer. So for me, it was obvious that we are going to release a Lego Mindstorms version of their robot. It will be available on the market as an extension set to the Home Edition version (art. 31313). The expected release date is december 2018 and it will be exclusively available at the Toypro (web)shop. The price of the extension set will be approx. 100 euro. Please note that you need the Home Edition to build this model. The soccer robot looks like this in real: And this is the version I made: This version is controlled by the infrared sensor plus the corresponding remote control. I'm working on a version with the Pixycam, that will be able to go to the ball autonomously. The omni wheels are the only parts that are not Lego. Please let me know what you think of it.

In the Netherlands, in the last class of the secondary school, you have to write a study project (for the Dutch: "een profielwerkstuk"). My son (17) choose to build the soccer robot from the Eindhoven University. More information about the real robot can be found here: http://www.techunited.nl/en. For the study project, my son wanted to know if it would be possible to build a single robot with the same functionality as the real one, meaning: The robot should drive in any direction using omni wheels The robot can see the ball The robot can drive towards the ball The robot can grab the ball The robot can shoot the ball The robot 'knows' its location on the playing field The robot has been build by Lego Mindstorms, with a total of 4 EV3 bricks, 9 large motors for the movement of the robot, a Pixycam camera for the vision, 2 large motors for grabbing the ball and 2 medium motors for the shooting. A gyro sensor is used to make sure that the robot only makes one full turn (360 degrees) when it is searching for the ball. Apart from the Pixycam, everything is regular Lego. The result of his study project is shown on the picture below. The robot is able to drive, locate the ball (it should be in a range of 2,5 meters otherwise the camera won't see it), drive to the ball using a simple PID control algorithm, grabs the ball and shoot the ball (if you click on the picture below you will be teleported to my Flickr page containing more images of the robot): Last Saterday, during the open house of his school, my son was invited to demonstrate the result of his study project to the visitors. A small video of the robot during the demonstration can be viewed on my Youtube channel. Please let me know what you think of his study project. And if there is more interest, I can post some more details. Kind regards, Hans
