INTRODUCTION
AndroSot, were the size dimension of the android is proportional to that of a human being.
Androsot is the newest type of Robot Soccer realized by Humanoid Robot. The operation
mode is mixed with automatic control method based on camera vision and remote control
based on wireless communication.
For this category of AndroSot, the match will be played with this rule :
1. Each team have 3 robots with wireless control.
2. At least one of the three players use automatic control method based on vision.
3. Only one computer to control.
4. There are only two or one camera outside the robot for each team’s vision control. But, the
number of the camera inside the robot will not limted.
5. There is only one player to control the robots.
OBJECTIVE
The objective of doing this project Androsot games :
1. To study the rules, scenario and strategy of Androsot games.
2. To understand the scientific concepts and technological developments involved.
3. To identify the effective strategy to winning the Androsot games.
RULES OF ANDROSOT GAMES
THE FIELD
For Androsot Games the playground should be a black wooden rectangular playground
220cm X 180cm in size with the surface texture of the board like a ping pong table and the
colour of the markings on the playground will all be white with width 2cm.Then, a white
side-walls will be used with 2.5cm thick and 5cm high . The topside of the side-walls shall be
transparent plastic walls with the thick is 2.5cm and height is 10cm. A solid 10cm X 10cm in
size of isosceles triangles shall be fixed at the four corners of the playground to avoid the ball
getting stuck in a corner. Next, the goal is make of transparent plastic to block the ball flying
to the back with 80cm width , 40cm depth and 60cm height.The line of the goal area is white
line colour which is 80cm long so that it will be recognize as a goal when the ball cross the
line.The goal area is a 90 X 15cm area in front of the goal line. In this area, only goalkeeper
should be in this area. Lastly , the penalty area is a 110 X 35cm area in front of the goal line.
In this area, the opposite party robot should not be here.
THE BALL
A ball that suitable for Androsot Games is an orange tennis with 6.4cm diameter and
56g weight.
THE COMPETITION SYSTEM
There is only one person to operate the robot by only one way of using computer with
wireless communication system. Then , each team can use only two or less cameras with
height 2.5m and should not affect the opposite team’s cameras. The robots can use embedded
vision control. At this time, embedded computer can be used to perform vision operation .In
one team, there should be one or more robots use control method based on vision with the
lighting condition in the competition site shall be fixed around 1,000 Lux.
THE ROBOTS
The robot should be like humanoid robot with two arms and two legs and can move within
30s after the beginning of competition. Then, it is also must have the ability of basic
movement such as move forward and turn .The robot’s leg should be have the ability to
stretch and ability to uplift when walking. Besides, the robot must stand up all by itself when
it falls down . The size of the robot should be :
Height : 20cm – 40cm .
Width : Not larger that the height
Length (robot’s arm) : Not longer than the leg
Weight : No limited.
Accessory : module, sensor, camera, controller (inside the robot’s body)
GAME DURATION
The duration of a game shall be 7:5:7 minutes , two equal periods of 7 minutes each and a
break of 5 minutes. In the competition process, when it stop for a robot exchange, the
substitution should be cut off from the game duration. Besides, if there is no winner when the
game duration is over,it should taking a break and competing for 3 minutes in the overtime
period. In the overtime period, by the rule of Golden Ball, the winner is the team that goal
first. If the score of the two team is still the same after the overtime period, performing the
spot kick form No.1 robot in turn to have the winner and shooting robot can kick only once.
(b) Game start:
The games will start with this steps :
1. Decide the active team by throwing coin.
2. The active team firstly selects the goal.
3. The robots will be placed freely at own half playground and the goalie must be placed
at the goal area.
4. The ball must be placed at the center position when goal or a half time.The active
team must kick the ball to own side half playground.
So, it is also same when the time to exchange the half playground when a half time is
over.
THE WINNER
The team shall be scored when the whole of the ball passes over the goal line. The winner of
a game shall be decided on the basis of the number of goals scored.But, if the discrepancy
number of goals scored exceed 10 when a half time is over, the game is over.
UNIVERSITI KEBANGSAAN MALAYSIA VS POLITEKNIK UNGKU OMAR
Based on the video of Androsot games during 7th FIRA MALAYSIA CUP 2014 between
UKM and PUO on youtube, we have discuss about the scenario and strategy from this match.
To watch the full video, you can click this link :
https://www.youtube.com/watch?v=aAdvNDAltfg .
STRATERGY
We will discuss the strategies used from the video of Androsot games between UKM and
PUO. First of all, the robot blocked the opponent so that the game will foul and it will start
again. It also include in rules where the robots were colliding then it can be called as foul.
Second strategy that we discussed is where the robot kicks the ball towards the wall so that
the ball reflects and enter the goal spot.
The robot runs faster towards the ball and quickly kick the ball away from the opponent. This
is a great strategy where the opponent cannot rotate 360 degree faster to get the ball at its
back.
Last but not least, we can see the goalkeeper has its own strategy which when the ball come
to goal spot, the goalkeeper stop the movement of ball with its body. Even though it does not
have a gripper to grip the ball, the goalkeeper catch it with its body.
SCENARIO
Based on the video, we can see that there is a scenario in this Androsot game which is free
ball. The referee will call a “free ball” when a robot is colliding with other of the opposite
team, either intentionally or otherwise the referee will call such “fouls” that directly affect the
play of the game. Next, a stalemate occurs for 12 seconds outside the goal area. For this rule,
a stalemate occurs when no robot is touching the ball or if two or more opposing robots are
blocking the ball.
When a free ball is called by the referee, the ball will be placed at a relevant free ball
position. The other robots can be placed freely outside the quarter where the free-ball is being
called. After the referee gives the signal, the robots may start the game and move freely.
Furthermore, in this game between UKM and PUO, there’s a scenario where the whole of the
ball passes over the goal line. A goal score will be given to the team.
CONCLUSION
After watching this video, we can conclude that the match was so boring. This is said because
there’s only a few scenario that happened in this game such as free ball, fouls and goal. So,
they are not really compete to each other. In order to make this game challenging, these two
teams should improve their robot with other strategy to make the robots more active during
the match. The robots should have ability to move faster than usually they used to be. Also,
they should have flexible body so they can always stretch their body to block the opponent
ball from entering the goal line. As we can see from this video, it will be more interesting if
theres other scenario happen during the match such as penalty kick, free kick and goal kick.
The teams should analyse and upgrade their robot abilities from time to time to make sure
that the competition between two of them will be more interesting.
