Prelude
In 1957 Soviet Union made the first launch in the Sputnik program - the very first satellite
designed and created by humankind. It was a 58 cm diameter polished metal sphere, with four
external radio antennae to broadcast radio pulses. The era of space exploration has begun.
Since that time hundreds of satellites continue to fill the space surrounding our planet and help
people in solving every day routine. One satellite usually serves the needs of people for several
years and then it goes down into the ocean or goes up to outer orbits and cannot return to the
Earth. However a lot of crashes happen as a result of satellite collisions with other objects in
the Space. Such kind of crashes leads to a large amount of debris polluting the near-Earth
space. According to scientists there is more than 100 thousand of debris 1x1 cm in size
weighing more than 5000 tons on the orbits 2000 km above the Earth. Considering all the tiny
objects the amount of debris reaches 300 million. Meanwhile even the collision with 1 mm size element speeding up to 10-15
km/s is able to destroy the whole space station.
In order to resolve the space debris problem the area around the Earth should contain factories-satellites for collecting and
recycling any kind of space debris. The factories could be completely automated and special robots will explore the Outer Space
to discover artificial objects and distinguish satellites in service from real debris.
Challenge Overview
The mission of the robot is to collect all the Space Debris and Failed Satellites and to load them into the Factory Satellite. Valid
Satellites must remain in the orbit. The robot must return in the Base zone (Earth) after completing the task.

Rules & Regulations
1. The number of the challenge objects is determined in the competition day before assembly time. In order to do this 10
cards with possible combination of the challenge objects are put in a non-transparent box (download cards). The number of
the objects on the cards is from 6 to 8 and 2 or more objects of the same type can be used. One of the card is taken for the
box and it will determine the combination of the challenge objects which will be used in all rounds during this competition
day.
2. Before the round starts (post-quarantine) the location of every challenge object is determined. The following rule is used:
every arc of the Satellite Orbit (the arcs between intersections of the Satellite Orbit and Factory Satellite orbit) can contain
from 0 to 2 challenge objects, two objects on the same type cannot be located on the same arc and two adjacent positions
(see markers on the Satellite Orbit) cannot be occupied by the challenge objects. The location of the challenge objects will
be fixed for all participants in the round. This method to determine the challenge object positions will be made for every
round during the competition day.
3. Multiple programs in the robot are allowed. For scoring rounds, the participants are only allowed to choose a program and
press the enter button to run it. Participants are not allowed to make any additional input or setting to the chosen program.
4. The robot begins in the Base area (Earth) and finishes in the same area.
5. The Factory Satellite moves counterclockwise along the Factory Satellite Orbit on the playing field with a speed from 5
cm/s to 10 cm/s.
6. The robot must start within the Base area (Earth). The robot must be placed completely in the Base area. The participants
arrange the physical position of the robot to their liking before the attempt starts.
7. As soon as the robot has been arranged and the Factory Satellite has arrived to the starting position at the playing field the
judge gives the signal to start.
8. The mission of the robot is to collect all the Space Debris and Failed Satellites and to load them into the Factory Satellite.
9. Valid Satellites must not be moved from their initial position. A Valid Satellite is considered as moved if it is shifted from
its plate or both the satellite and plate are completely outside of the green line representing the Satellites Orbit. Penalty
will be given for every Valid Satellite moved from their initial position.
10. An object is loaded into the Factory Satellite only when the object is completely loaded into the container of the Factory
Satellite (the white cylinder).
11. The robot is allowed to touch the Factory Satellite, to handicap its movements or to stop it. If the Factory Satellite got off
its orbit as a result of the robot’s actions the attempt will be stopped. Scoring will be made for all the challenge objects
handled by the robot till this moment.
12. When the robot enters completely to the Base area and has stopped moving, attempt will be stopped. The robot is allowed
to pass through the Base area (even completely) without movements ceasing. If the robot completely enters to the Base
area and stops (for example to perform a turn), this action will be considered as the finish and the attempt will be stopped.
13. The attempt and time will stop if:
The robot completely enters to the Base area and has stopped moving.
Any team member touches the robot after it starts or touches any object on the field.
The Factory Satellite got off its orbit as a result of the robot’s actions.
Challenge time (2 minutes) has ended.
Participant call for "Stop" of the match.
Violation of the rules and regulations herein.
Scoring
1. Score will only be calculated at the end of the challenge or when time stops.
2. A space Debris item or a Failed Satellite is completely outside of the green line representing the satellites orbit = 5 pts per
item.
3. Placing a Space Debris item completely into the container of the Factory Satellite = 40 points per item.
4. Placing a Failed Satellite completely into the container of the Factory Satellite = 50 points per item.
5. Moving of a Valid Satellite completely from its initial position, a penalty will be subtracted = 15 points per item.
6. The robot finishes completely in the Base area (at least one Space Debris item or Failed Satellite is moved completely
outside of the green line representing satellites orbit) = 20 points.
7. Maximum score = 330 points.
