<DIV dir=ltr align=left><SPAN class=216331908-01102007>One of the older
proposals for resolving this issue (that no-one has mentioned for a while) is to
have a standard battery pack for all robots on all teams. An
appropriately limited energy source forces some serious changes in
strategy:</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=216331908-01102007>+ Continuously running
robots from one end of the field to the other at high speed is no longer
possible.</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=216331908-01102007>+ Dribbling the ball for
long distances is costly in terms of energy, particularly if back spin is being
applied to the ball.</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=216331908-01102007>+ Indiscriminate use of
high power kickers will drain energy.</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=216331908-01102007>+ Heavy large robots will
use more energy, encouraging lighter, smarter robots.</SPAN></DIV>

<P>I believe a lower speed ball would not improve passing.<BR><BR>The current
problem is that robots are too fast and has unlimited energy. And they are too
clumsy in term of ball handling. So passing takes a longer time compared to
blocking a ball as the receiving robot takes a while to get control of the
ball and change direction, compared to the defending robot, which are capable
of accelerating to a postion at very high speed.<BR><BR>We need slower robot,
or more dexterous robot (able to dribble faster and more skillfully) or bigger
field.<BR><BR>Regards<BR>BengKiat<BR><BR><IMG height=16

<BR>> <BR>> This is Roman from the Georgia Tech team. I think that a
larger field<BR>> would be an improvement and add to the gameplay
possibilities like<BR>> passing and better team coordination. However I am
interested to know<BR>> what the primary objective is in increasing the
size, I think that<BR>> that will partially dictate just how and how much
to change the size.<BR>> <BR>> Would this mean that the max kicking
speed would also change?<BR>> <BR>> ~Roman<BR>>
