Building Instructions -

• FIRST LEGO League

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.

Background

Our Lander doesn’t have working parachutes, thrusters, or cushions, but one important feature is realistic … it’s very fragile.

Mission

Get the lander to one of its targets intact, or at least get it to base.

Scores

• Move the lander to be intact, touching the mat, and completely in its target circle: 22 OR
• Move the lander to be intact, touching the mat, and completely in the northeast planet area: 20 OR
• Move both parts of the lander completely into the base: 16
• Possible scores: 0, 16, 20, 22

Scoring Requirements

• The result must be visible at the end of the match.
• The lander is “intact” if its parts are connected by at least two of its four tan location axles.

Background

For rovers in other worlds, getting stuck is definitely not okay! Teams of rovers can help each other, but a lone rover needs to be very careful.

Mission

The robot or whatever agent-craft it sends out needs to cross the craters model completely, by driving directly over it. Not near it. Not around it.

Scores

• Robot or agent-craft crossed the craters model completely: 20
• Possible scores: 0, 20

Scoring Requirements

• All weight-bearing features of the crossing equipment must cross completely between the towers. > Only allowed method. Must be observed by the referee.
• The crossing must be from east to west, and make it completely past the flattened gate. > Only allowed method. Must be observed by the referee.

Background

If a satellite doesn’t have the correct velocity and distance from earth, it can fall, drift away, fail to function or get destroyed by debris. Propulsive adjustments need to be performed with precision.

Mission

The robot needs to move one or more satellites to the outer orbit.

Scores

• Move any part of a satellite on or above the area between the two lines of the outer orbit: 8 each
• Possible scores: 0, 8, 16, 24

Scoring Requirements

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

Background

Though spacecraft travel crazy-fast, even the shortest trips involve a lot of time for the traveller’s body away from labour and recreation, which is bad for the heart and lungs.

Mission

The robot needs to repeatedly move one or both of the exercise machine’s handle assemblies to make the pointer advance.

Scores

• Get the pointer tip completely in orange, or partly covering either of orange’s end-borders: 22 OR
• Get the pointer tip completely in white: 20 OR
• Get the pointer tip completely in grey, or partly covering either of grey’s end-borders: 18
• Possible scores: 0, 18, 20, 22

Scoring Requirements

• Advance the exercise machine’s pointer along its dial by moving one or both of the handle assemblies. > Only allowed method. Must be observed by the referee.
• Results must be visible at the end of the match.

Background

Gardening is easy, right? You just need a truckload of rich soil, some rain, sun, fertilizer, helpful bugs, CO₂ and a rake but what if you were orbiting Neptune, in a room the size of a minivan?

Mission

Move the push bar the right distance at the right speed, to get into the green scoring range.

Scores

• Spin the food growth chamber’s colours so the grey weight is DROPPED after green, but before tan, by moving the push bar: 16
• Possible scores: 0, 16

Scoring Requirements

• The result must be visible at the end of the match.
• Spin the food growth chamber’s colors must be spun by moving the push bar. > Only allowed method. Must be oberserved by the referee.

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.

Building instructions for the catapult that could be placed over the LEGO Mindstorms EV3 Brick. The idea of the catapult it to throw objects. The fact that it is over the brick makes it very convenient to place the motors below the brick and to use the Catapult. 

This robot construction itself was used in the FIRST LEGO League Senior Solutions competition

Building instructions for this LEGO Mindstorms EV3 attachment for the FIRST LEGO League Nature's Fury robotics competition

This attachment presents a way to mechanically align the robot to a mission model and solves the Cloud mission from FLL 2014. 

Building instructions for a LEGO Mindstorms EV3 Ambulance Robot Attachment for the FIRST LEGO League 2013 Nature's Fury robotics competition.    The attachment grabs the ambulance car and slightly lifts it. The rubber bands help with triggering the attachment at the right time

Building instructions for the One Attachment. Built from LEGO Mindstorms EV3 parts and with an Ultrasonic sensor we've used this attachment to accomplish most of the missions at FIRST LEGO League 2013.

SIngle robot attachment, many points. 

If you take a look at the videos for this attachment you will see a nice idea on taking the track and the ambulance. These two vehicles from the FIRST LEGO League 2013 competition had to be collected and returned back to base.

Building instructions for the LEGO Mindstorms robot attachment used at the FIRST LEGO League Natures Fury Competition. This robot attachment takes two of the building and moves them without demolishing them. It is a good example of the use of gear wheels and worm gear. The gear wheels move levers in opposite directions. 

Attachment part of a series of robot attachments for accomplishing the FIRST LEGO League 2013 competition. This specific construction lifts the two vehicles. It uses rubber bands for locking the levers. Take a look at the video tutorials for details explanation on how it works.

Build from LEGO Mindstorms EV3 parts.

Kiril Mitov's most favourite attachment. To quote him "I had a really great fun building this attachment and recording the videos for it".

It's an attachment with a Rubber band and a Flywheel and a Gear Wheel and a Worm Gear. So much knowledge in just one small attachment. The goal of the attachment is to be able to have an active attachment without actually having a motor. So you can place that attachment and it will do the work for you instead of using a motor to power it. 

Build with LEGO Mindstorms EV3 set.
