WE HAD PROBLEMS WITH BATTERIES TOO LAST YEAR. THE WEIGHT OF THE BATTERY APPEARED TO AFFECT PERFORMANCE. THIS YEAR WE ARE USING ONLY THE RECHARGEABLE NXT BATTERIES. WE HAVE NOT ENCOUNTERED ANY PROBLEMS YET. WE HAD PROBLEMS WITH THE SIDE WALLS AT THE TOURNAMENT. THE ROUGH PAINT MESSED US UP TOO. I GUESS WE NEED TO TAKE  THAT INTO CONSIDERATION AT STATE COMPETITION AND MODIFY OUR ATTACHMENT.

To: [log in to unmask]

If it is a speed and power issues the only thing that comes to my mind is the power source.  We purchased a new rechargeable battery this year and we were swapping out old battery and new one.  When ever we used the new one the robot got a huge power boost.  So we stuck with the new one from that point going forward. At tournament we used a touch sensor to ride the wall to the other end of the table, we used a diffrent type of paint for the side walls and the more tacky paint at tournament was messing us up. A redesign of the touch sensor led to solving the problem, but it worked great in practice.

The kids' robot acted so much different at the tournament then on the test map we have to train on.  Our mat is kinda dusty and while on leveled, was not 100% flat which is the only two factors I can think of that would make it act differently. My question is what else can cause a robot to act much faster?   Battery power was not an issue.  If anything, it had less power on the day of the tournament then it had the day before when we ran it to test.  One of our kids joked that it got too excited, which is funny, but clearly not the issue :) I also wonder if the 4 degrees or so our table is off was the reason.  We leveled the table we used and it didn't seem to affect it. 

    Oh, and apologies to the creators of the brick and motors.  The team discovered
 it was the design that lead to the greater amount of inconsistencies in their run :)
  Any thoughts on the too fast robot issue would be helpful.
