Depending on how many motors you guys are using, it appears that your bot could easily be changed to where all 4 cim motors are in drive. Instead of using 2 cims for the shooter use 4(or 2) 550's with
CIM-U-LATOR gearboxes. This will greatly improve the power of your drivetrain. I also recommend adding 2 wheels in the center of your robot(should be very easy with the kitbot frame) to make it easier to turn.
These simple changes will greatly improve the preformance of your robot.
Here's why, and
here's some instructions if your feeling a little confused. I hope this helps and good luck this season.
