Building Instructions -

For World Robotics Olympiad Ball Collection competitions we prepared an interesting Robot Base Chassis that could be extended with a container. The container contains the ping-pong ball. A mechanism collects them. This LEGO Mindstorms EV3 building instructions are for the chassis of the robot and were one of the versions from a series of robots.

Background

Soon after a launch, rocket engines often separate away from spacecraft by design, but that’s long before the spacecraft leaves the pull of gravity. So why doesn’t the spacecraft fall back to earth?

Mission

The robot needs to impact the strike pad hard enough to keep the spacecraft from dropping back down.

Scores

• Get the spacecraft to go so fast and high that it stays up, by pressing/hitting the strike pad: 24
• Possible scores: 0, 24

Scoring Requirements

• The result must be visible at the end of the match.
• Activate the spacecraft by pressing/hitting the strike pad. > Only allowed method. Must be observed by the referee.

FIRST^® LEGO^® League mission requirements need to be achieved by your robot through its programs and its use of equipment. You’re allowed to hand-rescue your robot, but that does cause this penalty. Be sure to pay extra attention to the rules where they talk about “Interruptions"

Penalty

• If you interrupt the robot: minus 3 each time
• Possible penalty totals: −18, −15, −12, −9, −6, −3, 0

Scoring Requirements

• Interruption needs to be observed by the referee.
• Upon penalty, the referee will place one penalty disc in the southeast triangle as a permanent interruption marker.
• You can get up to six such penalties.
• If a penalty disc comes off the triangle, it is simply returned, with no effect on score.

Background

The chance of a “serious” meteoroid hitting earth in our lifetime is extremely low, but it’s not zero, and the devastation could truly wipe us out. How will scientists and engineers keep us safe?

Mission

From west of the free-line, send one or both meteoroids independently to the meteoroid catcher. “Independently”: see also M01, Section “Scoring Requirements”.

Scores

• Meteoroid(s) touch(es) the mat in the centre section of the meteoroid catcher: 12 each
• Meteoroid(s) touch(es) the mat in either side section of the meteoroid catcher: 8 each
• Possible scores: 0, 8, 12, 16, 20, 24

Scoring Requirements

• The result must be visible at the end of the match.
• The meteoroids need to be sent over the free-line to touch the mat in the meteoroid catcher > Only allowed method. Must be observed by the referee.
• The meteoroids must be hit/released while they are clearly and completely west of the free-line. > Only allowed method. Must be observed by the referee.
• While between hit/release and scoring position, the meteoroid must be clearly independent. > Only allowed method. Must be observed by the referee.
• If ever the ring-set meteoroid is off its ring, you may remove the ring from the field by hand. This is a special exception to the rules.

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.
