Introduction
The IEEE
Open has the objective of presenting a high level challenge
to the students. In this league any equipment can be used to
assembly a autonomous robot which ought to accomplish a task
which is changed each year. The tasks of the IEEE Open try
to reproduce the challenges of the real robotics in a minor
scale.

This category has
been played in Brazil since 2003. The last results are:
Rules and Attendance
F. A. Q.
Q: What are the blocks
made of? What is the cube mass?
A: Blocks are made of wood. The mass of each cube should
be between 60 – 90 grams.
Q: Can more than one robot be carried per time?
A: Only one robot can be on the scenario at a time. It
is not allowed robots that can split in two or more robots
during a round. Also, no team is allowed to use one robot in
a round and other robot in next round.
Q: Can the cubes be place one over the other in the
proposed sequence?
A: No. Cubes should be place ones next others in
horizontal way.
Q: The 300mm limitation remains for all the challenge or
it is only for the beginning?
A: During all competition, the initial configuration of
robot must remain in a cube of 30x30x30cm. Then robot can
autonomously deploy any kind of griper, arm or mechanical
extension to take, manipulate or transport cubes.
Q: Can the team choose the robot orientation even though
the start points are chosen by the judge?
A: No. Initial position and orientation will be assigned
by judges. This weren’t clearly stated in version 1.0 of
rules. New version of rules has specification of this.
Q: The positions of the colors in the fabrication zone
are always the same or they are randomly chosen in each
round?
A: When all robots are present, the round starts. At
this time, judge will place group of products (cubes)
randomly and it will be the same for all teams. Remember,
that no member will be able to modify or reprogram their
robot until whole round ends. This assure an equivalent
situation for all robots.
Q: The color of the graphics do not correspond to magenta.
A: Version 1.1 of rules fix this color inconsistency.
Q: In the Spanish version... are 4 or 5 the number of
teams for the finals??? There are two different references
to the number of teams in the finals (4 and 5).
A: Version 1.1 of rules correct this inconsistency.
Q: There is any fixed distance between the piles of
blocks and the production zones?
A: The piles should be in the center of each sector of
production zone.
Q: Is there any restriction regarding the number of
blocks each robots get per time?
A: No, there is no restriction in the number of cubes
that robots can transport at a time. But, there is
penalization if a cube is dropped off or forgotten.
Q: There are restrictions regarding the robot leaving the
arena. Is there any kind of restriction in the entrance or
other areas?
A: Robot can’t leave the arena, but can go freely inside
producers’ zone, vendors’ zone and central corridor.
Q: As states in the rules "... The robot should be able
to differentiate color of each product...". If the team goes
for another approach without using a color sensor, is there
any problem?
A: Teams can use any approach to collect cubes and to
deposit them on vendors’ zone. A simple approach could be to
take one cube of each and deposit them in vendors’ zone.
This approach can give an easy way to obtain 100 points per
package of 5 cubes deposited inside a sector. Nevertheless,
an approach that consider colors detections and cubes
manipulation can give a way to obtain 300 point per package
of 5 cubes correctly deposited inside a sector. Clearly,
vision capabilities can make a big difference in the final
score.
Q: If more than 5 blocks are placed in the saling area do
we get a bonus for excedents??? If we complete the 5 blocks,
do we receive an extra bonus for the correct order?
A: No more than a package of 5 cubes is allowed inside a
sector of vendors’ zone. If so, it will consider as
incorrect. The maximum number of correct package of 5 cubes
that can possible make is 12 (See figure 6). In this case,
and without any penalization, the maximum possible score is
3660 points (300 x 12 + 1x5x12). That is: 300 point for each
package correctly deposited and 1 point for each cube inside
vendors’ zone.
Q: Is there any tolerance for the distance between the
blocks in the deposit?
A: To consider that a package of cubes is inside a
sector, no cube should be in contact with black line.
Q: Figure 7 does not correspond to the explanations of
correct and incorrect. When a reference is made in examples
1 and 3 one can understand that the content was exchanged.
A: Version 1.1 of rules fix this inconsistencies.
Q: What is the correct position of the cubes? Item 2
presents... "The correct order is the following: a red,
cube, a green cube, a cyan cube, a magenta cube and a yellow
cube." However, item 3 informs... "Vendors need that cubes
are placed in the following order: cyan, red, yellow, green
blue, magenta, as is shown in figure 5".
A: Version 1.1 of rules fix this inconsistencies on
correct and incorrect forms to place package of cubes inside
sectors of vendors’ zone.
