Building Instructions -

• Java

Building instruction for both EV3 and NXT. The whole catapult is build in exactly 78 steps.

Pallo, from Ancient Greek, means "to throw" or "to hurl"—a root of the modern word "catapult".

Pallo is a robot made of two parts. The first part is the catapult! It contains no electronic components and uses two rubber bands to launch a projectile toward the second part. The second part is the target. It features a color sensor which, using a piston with differently colored sections, detects how accurately the target has been hit. Good luck with the shooting!

With this attachment we complete the Elevator and Steel construction for the FIRST LEGO League 2019-2020 competition. The attachment is placed on the Whakatae - LEGO Education SPIKE Prime Competition Box robot

Building instructions for a LEGO Mindstorms EV3 robot where the motors are at the back of the horizontally placed brick and they are placed vertically. This construction is difficult to turn with but at the same time is quite high and could be used as a base for different trucks or animals. 

Vex IQ robot base which could be used with different attachments. The gravity center of this robot is in the backside and it has a lot of space in front for attachments.

Background

To live away from earth, it would help if we were good at detecting and mining resources under the surfaces of other planets, moons, asteroids, and even comets.

Mission

The robot needs to get all the core samples out of the core site model, then it has options for what to do with them as described here, and in mission M03.

Scores

• Move all four core samples so they are no longer touching the axle that held them in the core site model: 16
• Place the gas core sample so it is touching the mat, and completely in the lander’s target circle: 12 OR
• Place the gas core sample completely in base: 10
• Place the water core sample so it is supported only by the food growth chamber: 8
• Possible Scores: 0, 16, 24, 26, 28, 34, 36

Scoring Requirements

• Results must be visible at the end of the match.

This construction is taken from here. It is a little bit modified so you can build it from one EV3 Set. We made it because we thing it is genius. We are "angry" in the good meaning оf the word, because we didn't invent it. We hope that you will have the same fun as we do with it.

We think that this thing is a perfect example of balancing and mind scratching behavior. You also need to be precise with the length of the ropes. And the best part of it is that you don't need to program anything. 

Have fun and good luck!

This device is designed to be attached to "LEGO Mindstorms Robot with a large inertia cargo". It is a color sensor that goes on the caster wheel of the robot. In this case, the sensor will follow the robot.

These are instructions prepared by LEGO.

A similar LEGO attachment the previous once, but this one is with a different gear ratio. Again using a frame, two axles and two gears you can change the direction of the motion.  

This attachment is accomplishing three missions from the FIRST LEGO League 2022-2023. It is for the Chain Monster robot

This robot was designed for the VEX IQ Challenge 2019-2020. It could push four hubs simultaneously. It can carry one. And it call pull itself on the bar at the end of the run. We've used four omni wheels of which the two at the back are the driving wheels.

Demo program can be found at Program for Winner - VEX IQ Competition Robot for the 2018-2019 Challenge.

Interesting and useful attachment for dropping a LEGO human at a specific location. It uses a lever and a gear wheel. When the lever is pressed the wheel rotates.

The attachment is constructed from LEGO Mindstorms EV3 sets.

Background

It is amazingly expensive to send heavy stuff like construction material into space, so scientists and engineers are instead learning how to print what they need in space, using available extraterrestrial elements.

Mission

The robot needs to get a regolith core sample and place it into the 3D printer, which will cause the 2 × 4 brick to pop out. The ejected 2 × 4 brick can then be delivered elsewhere for more points.

Scores

• The 2 × 4 brick ejected and completely in the northeast planet area: 22 OR
• The 2 × 4 brick ejected and not completely in the northeast planet area: 18
• Possible scores: 0, 18, 22

Scoring Requirements

• Results must be visible at the end of the match.
• Eject the 2 × 4 brick by placing a regolith core sample into the 3D printer. > Only allowed method. Must be obserserved by the referee.

This LEGO attachment connects a LEGO Mindstorms EV3 Motor with a LEGO Technic Linear Actuator. The connection is through a couple of gears which makes the whole instructions quite interesting and useful as an example. 

The attachment was used during FIRST LEGO League 2014 Robotics competition.

With this LEGO Education SPIKE Prime attachment we accomplish the basketball mission from the FIRST LEGO League 2020 RePlay competition. The goal of the mission is to put the ball into the basket and to have the basket up at the end of the round. This is a complex attachment. It uses gear wheels and warm gears to transfer the power from the motor to the top of the attachment. At the top of the attachment there is a wheel with a rope. The rope is build with LEGO Education SPIKE Prime parts. If you have the chance, use a different LEGO rope, but if you don't that this one will be ok.

This robot is a spin-off of the Useless machine built from LEGO Mindstorms EV3. This robots mission is to be the last to press the button it holds.

This is an 8 bar lifting robot. Way should I build this instead of Roberto bot you ask? Because it is... well... it lift thing straight up, it lift 'em higher, it's more beautiful than Roberto and is more bad ass looking than 4 bar lifting mechanism. OOoohhh, and one more thing it may use the same program as Roberto Bot With Four Bars Lifting Mechanism.
