DPRG mailing list archives: [DPRG] Rules

Tue Sep 11 08:57:22 CDT 2001

DPRGers,

1. I would suggest we score the can-can according to Kip's suggestion. 
After all he is the senior spokesman when it comes to these rules. 

What I heard Kip say was "No points for identifying cans unless 
"identified" clearly by the robot, or unless clearly "identified" by 
the robot due to the method the robot uses to collect a can. 
Example: Gripper, or a collecting mechanism that must be 
aimed or manipulated to collect the can. 

No locating points for blind scooping, sticky methods, or "trapping" cans. 

2. We have discussed this at group activities and on line (I believe) 
after the past two Roborama's, so I feel it is not a "new" or "changed" 
rule. Also, I believe we can document that this was clearly the 
intent of the rules makers.

3. As best I can determine, this will not greatly effect the out 
come of the contest. The robots that scoop the most cans 
are still likely to win the contest. That is, unless a robot can 
locate and retrieve cans as per the rules. Then that robot 
gets the advantage in points and would most likely win. 
Visa Vi, the more talented robot wins.

My $.02!

Any two cans in any of the center areas (D, T, or E) are in a line.  After
all it only takes two points to define a line.  All the scooper has to do is
run at an angle across the area to get more than one can.
