Playing Football with robots is extremely fun. It could be part of the classes, it could be part of demonstration days. This is a EV3 LEGO Mindstorms Project including the programs for controlling the WRO Football Striker and the WRO Football Goalkeeper, as well as all of the necessary My blocks.
Have you even tried to move the robot not in rotations or degrees or seconds, but in metres. In this episode I am building a new block that could be used to move the robot a specific number of millimetres (mm). You could directly download and use it in your programs.
Another example for a quick pinless attachment build with LEGO Mindstorms EV3 robots.
Това е насочващ механизъм, който работи и изглежда като опашка на риба, за да може да направите най-готината риба робот! Опашката използва среден мотор за да се движи наляво - надясно. Може да я свържете с други модули за да направите собствено морско същество с опашка!
This is the attachment to accomplish Fll 2019 M07 mission with the Dominator robot. You can see how to attach the attachment to the robot in this tutorial.
This attachment uses a connector ("(98585) Technic Connector Circular With 2 Pin Holes and 3 Axle Holes") with 4 pins to connect with a knob wheel ("(32072 ) Technic Gear 4 Knob") of the robot. Because both elements are parallel one to another there is no jumping effect.
The attachment uses two pins, but it is easy to attach and detach because it uses "(6558) Technic Pin Long with Friction and Slot". When you attach or detach the attachment the slots are keeping the pins strong on to the attachment.
Also an attachment connected to the robot in this way, can be move to the rigth knob wheel or to the left knob wheel.
In many of the robots, we would use the LEGO Steel Ball so you should try to acquire one. Even better if you have two of those. One is available in the LEGO Education EV3 core set 45544, but the LEGO EV3 Retail Version 31313 does not have them.
One of the very good things about box robots is that you could easily align with them both to the front, to the back or to the rear sides. This aligning is helpful for FIRST LEGO League, World Robotics Olympiad or other robotics competitions with LEGO Mindstorms EV3/NXT robots.
