LEGO MINDSTORMS

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

A space telescope is astonishing, but it can’t beat the accessibility and simplicity of a college or science museum observatory – that is, if you know how and where to point it.

Mission

Rotate the observatory to a precise direction.

Scores

• Get the pointer tip completely in orange, or partly covering either of orange’s end-borders: 20 OR
• Get the pointer tip completely in white: 18 OR
• Get the pointer tip completely in grey, or partly covering either of grey’s end-borders: 16
• Possible Scores: 0, 16, 18, 20

Scoring Requirements

• The result must be visible at the end of the match.

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

Solar panels in space are a great source of energy for a space station in the inner solar system, but since things in space are always moving, aiming the panels takes some thought.

Mission

Solar panels need to be angled toward or away from you, depending on strategy and conditions.

Scores

• Both solar panels are angled toward the same field: 22 (for both teams)

• Your solar panel is angled toward the other team’s field: 18

• Possible scores: 0, 18, 22, 40 as shown below and seen from above your north border, facing north.

“Your” solar panel is the one on your west end of the table.

Scoring Requirements

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

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.

The first part of a box robot chassis for robotics competitions. The robot is quite large and this is why we split it into two parts - to make it easier to construct it. This is the second part. 

The robot is built with LEGO Mindstorms EV3, with an additional part for the walls used in the second part.
