Mindstorms Soccer Robot Inspired by Real Soccer Robot

[Bram], a 17-year-old robot fan from the Nertherlands, had an opportunity to watch a RoboCup soccer match played by autonomous robots, and was inspired to create his own Mindstorms version of the robot for a school project.

The robot he created is around 80 cm in diameter and is controlled by four daisy-chained EV bricks. There are nine large motors for controlling the wheels, two more large motors for grabbing the ball, and two medium motors for the ball-shooting mechanism. It uses a Pixycam for ball detection, and it can identify and move toward the ball so long as it’s within 2.5 m. A gyro sensor determines the robot’s rotational direction.

Our favorite detail of the robot is its giant omni wheels, constructed out of LEGO elements. Each one consists of sixteen Mindstorms-standard wheels arranged in a circle, with an offset double row of rollers to give the same angled effect as a Mechanum wheel’s rollers.

This story has even geekier roots. [Bram]’s robot was based off of the Turtle, a soccer-playing robot used to teach programming to college students. Like [Bram]’s creation, they also have omni wheels, and see with a Kinect as well as a 360-degree camera up top that uses a parabolic mirror to keep an eye on its surroundings. The Turtle uses a compass sensor to distinguish its goal from the opposing team’s goal.

Soccer Playing Robots Score on Human Goalie!

Soccer robot scores on humans

Did you know there’s a rather large community dedicated to making robots that can play soccer? Did you know they’re getting pretty good?

RoboCup is an international robotics competition held annually, first founded in 1997. The goal first and foremost is to promote robotics and AI research — and to do so, they decided to make the competition something that is publicly appealing — Why not one of the most popular sports around? The official goal of the project is to have a team of autonomous humanoid based robot players beat the most recent winning team of the World Cup, complying with the official rules of FIFA. This year, the RoboCup coincided with the real World Cup, and was hosted in Brazil.

There are several categories in RoboCup with various types of robots, and the mid-size team did pretty well this year.

Arguably, this is the most exciting game of all, because it gives a sense of what the current state-of-the-art in robotic soccer is, and how it stacks up to a team of moderately talented squishy bipeds.

We guess that’s a nice way of saying “non-professional soccer players”. Regardless though, they SCORED!
