Building Instructions

This is the robot that we use to demonstrate a solution for the World Robot Olympiad 2021 Junior competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition.

We started with this robot and it has a few good ideas. It can collect two cars at the same time. We later decided to go for a more powerful robot. Check out WRO 2021 Junior: Slaimi - a post season WRO competition solution robot

This is the robot that we use to demonstrate a solution for competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition. But after the competition we try to make a review and to see how we could have accomplish it. Our goal is to be better for next year.

This robot is quite powerful. The attachment mechanism on the front is one of a kind as it can do several things with a single motor: it can lift, it can unlock, it can grab. All of this thanks to the unique mechanism of gears

This is a version of the Gazon robot that has a single color sensor and is useful for cases where you still have not purchased a second color sensor, but need to start working on the FLL competition season missions

This is a light shield over the color sensor. Covered from the light the color sensor is much more precise.

Light Cooley is an extension of Cooley. We've added two Light/Color sensors to allow for lines to be followed and for the robot to alight to them and we've kept everything Cooley was cool and known about. Build a few attachments for it and take it on a ride for a FIRST LEGO League competition

This incredibly compact SPIKE Prime Box Robot is made for competitions like FIRST LEGO League (FLL) and World Robotics Olympiad (WRO). Whakatae (from Maori's word "whakataetae", which means "competitive") is long 17 LEGO units and is with a width of 15 LEGO units. In front of the wheels it has two color sensors which it uses to align. Whakatae also has two Large motors for moving and has two medium motors for attachments!

It's has "V2" in its name, because it's the second version of Whakatae - LEGO Education SPIKE Prime Competition Box robot. The difference between the two is that the first one can be built with only a Large Motor and a Color sensor in addition to the Base set, while this one needs an additional ball bearing. This provides this robot with a lot more stability and can be seen as a true upgrade to the first version.

Motorka, from Czech, means motorbike. Motorka is a motorbike with 3 tyres. Two at the back and one that steers the bike! The two at the back are powered by two medium motors and the one at the front - by one large motor. The robot uses various parts from the base set to look like a motorbike, for instance, at the front it has a color sensor that is used for the light of the motorbike!

Dominator is a compact LEGO Mindstorms EV3 Box robot from the family of the Roller Coaster and Kiddo box robots. Similar to the previous two robots, Dominator also can move its front part up, down, left and right. This robot also has the same length of movement as its two predecessors of this type - 8 LEGO pins on the side and up.

The difference is that Dominator has fewer parts and has a perfect center of weight that allows it to use large attachments and lift heavy objects without threatening its stability. The movement on the X and Y axes has the same gear ratio. The light sensors are attached to the movable part of the robot which enables it to both follow a line and recognize the color of various object with height lower than 7 LEGO units.

Pallo, from ancient Greek, means to throw or to hurl, which is a part of the modern name "catapult".

Pallo is a robot made of two parts. The first part of the robot is the catapult! It has no electronic parts and uses two rubber bands to shoot a projectile to the second part. The second part is the target. It has a color sensor, which through a piston with different colored sections, determines how accurately the target has been hit! Good luck with the shooting!

Calix, from latin, means cup. Calix is made to carry an object while following a black line. Most people, when they think of robotics, they think of how the robots may help them at home, with the chores that no one wants to do. This robot is a simple version of this. You can give it a cup in the kitchen and then it will deliver it to the end of the black line! The robot uses two SPIKE Prime medium motors to move and a color sensor to follow a line. At the front it has Large motor with a gear system that lowers and rises the "cup".

This incredibly compact SPIKE Prime Box Robot is made for competitions like FIRST LEGO League (FLL) and World Robotics Olympiad (WRO). Whakatae (from Maori's word "whakataetae", which means "competitive") is long 17 LEGO units and is with a width of 15 LEGO units. In front of the wheels it has two color sensors which it uses to align. Whakatae also has two Large motors for moving and has two medium motors for attachments! The best part is that in order to build this SPIKE Prime Box robot you only need the Base set, a Large motor and a color sensor.

Swing game is a SPIKE Prime robot that is a game played by two people. The goal of the game is for both LEGO people to reach the center of the swing, without it tipping over on either side. The LEGO poeple are placed on motors, connected to two technic gear racks, that move along the swing. The motors are moved by two controllers, one using a color sensor and one using a Large motor. If one of the LEGO people moves too far without the other doing the same, the swing will tip and game over! Good luck and have fun!

Nice idea. Lift the other robot and throw it in the air. Not easy, but Varna is trying to do it. It's a quite powerful robot with small wheels and gear ratio of x3. This means the power is increased 3 time from the motor to the wheel. 

Surely you can work with it and even improve it. 

Here is an idea. What if a robot does not need attachments. What if there is one special attachment on the front that could do most of the work? Probably an attachment that allows you to move a lever in any direction.

This here is a Box Robot with X - Y axys plane. This robot doesn't need active attachments because it has X - Y table that do the job. Imagine that there is a plane on the front of the robot. With the rack mechanism you can move to any coordinates on this plane. 

We have a lot of ideas how to make it even better. We will try to release them in the next few versions.

Building instructions for a Light LEGO Mindstorms EV3 Competition Robot that could be used in LEGO Robotics competitions. Compared with previous versions of this robot, this one has a Gyro Sensor.
