The Need For Change: The Need For Change Concerns voiced by competitors and National Reps
The RoboCup Junior Soccer Challenge, developed in 2000 has been solved.
There is a need for change, to attract new competitors and revive interest in current competitors
The focus on speed, power and aggression is not in compliance with RoboCup Junior ideals.
Too many robots are becoming evolutionary (handed down), or even manufactured, with little design input from members of current teams.
The Need For Change: The Need For Change RoboCup Junior is losing too many prospective competitors because the competition appears too strong or the robots too aggressive.
Games being contested by higher quality teams are slow because of “lack of progress” due to large robots and balls being trapped on walls.
Consequently the need for a new game focussing on robotic finesse and programming skill …..
A new generation!! (GEN II)
Considerations: Considerations The RoboCup Junior focus should be accessibility for as many students as possible within the educational environment.
The challenge should not be too complex for learners, early success should be easily accessible.
Robots should be given more variables within the game environment to maximise tactical options.
Ease of use and availabilty(economical) for the classroom.
Remove any advantage of power, speed and weight.
Reduce randomness within the game and maximise reward for programming finesse.
Leave the opportunity open for introduction of technological improvement and even tactics between robots in future years.
The GEN II Answer: The GEN II Answer GEN II Soccer Field playing area dimensions identical to the current RoboCup Junior Soccer Field 30 cm white borders inclined by 2cm at the outer edge Goal Specs identical to current goals All colours tested for discrimination between LEGO RCX and NXT as well as LDR light sensors. The GEN II field mat is made of textured banner vinyl. Roll resistant, durable and easy to clean.
Borders included with mat.
Classroom setup: Classroom setup Any classroom with a carpet floor.
Roll out the GEN II Robot Soccer mat
Place 12 mm high strips of wood under the borders.
Insert the goals
and let the fun
and learning begin
Competition Setup: Competition Setup Felt layered base
MDF the same thickness as border material.
Set up inclined
borders.
Add goals and play
Please Note: Please Note Investigations are being carried out to see if felt can be supplied attached to the mat.
45 degree angles should be cut into the corners of the borders (not shown).
The mat viewed here is only a sample. The final mat will cover the field and the borders.
Any wrinkles that are visible in this demonstration disappeared quickly as the mat sat on the floor for a longer period.
The goal bases are not inclined on an official field.
Suggested Rule Changes: Suggested Rule Changes If a robot kicks the ball out of the arena, they will be penalised with the ball being replaced behind them on the field.
If a robot leaves the arena it will be classed as “damaged” and removed for one minute.
Robots must release the ball within 45cm of first touching the ball. (1/4 of the field)
Ball capturing zones increased to 4cm deep.
Robots can only kick a goal from within their forward half.
Pushed goals are allowed from inside the penalty area.
Any robot vigorously spinning wheels on this surface will probably mark it and result in them being excluded.
A weight limit of 1.5 kg is necessary on the softer, ball roll resistant surface.
Robots have a size limit of 20cm diameter.
GEN II Tactics : GEN II Tactics A robot cannot attack the ball vigorously as the ball will go outside of the arena.
GEN II Tactics: GEN II Tactics With less speed and greater control, the ball stays in the arena and is moved to the robot’s advantage.
GEN II Tactics: GEN II Tactics A robot in the mid green area can choose to dribble the ball left until it detects the dark green area, veer right and kick for goal.
GEN II Tactics: GEN II Tactics The ultimate: a robot in the mid green side of the field can elect to travel down the field, using its compass and then kick left for goal.
This could be further improved if the robot found the dark green-middle green border, followed that line and kicked on reaching the black.
Other Design Options: Other Design Options Half circle 45 cm radius
Penalty Boxes
(Sizes negotiable)
