We don't usually weigh sub-systems unless we are bringing them as a part of our withholding allowance to a competition or we are looking to add/remove it from our robot, so we don't have an accurate weight for our gearboxes.

At the end of build season, our robot was about 10lbs underweight, so we added some steel blocks to the base plate to help lower our CoG and bring us up to 120lbs. The goalie stick weighed about 5lbs, so we took out some of the steel blocks when we added it.

The drop down omni wheels weren't as effective as we were expecting. When we were designing the drivetrain this year, we didn't know exactly what the rest of the robot was going to look like yet, so we made a strategic decision to put them on the back of our robot. The thought was that if we spun out of a t-bone around the front of our robot (since that is where our traction wheels would be), we would be on the offensive side of the defender after getting out the the t-bone, making it more difficult for the defender to re-engage.

Unfortunately our robot's CoG ended up being toward the back, meaning that most of the weight was on the omni wheels instead of our traction wheels, which meant we didn't have much traction when trying to spin out of a t-bone. As a result, that weren't very effective for us, and we rarely used them. I believe there is potential for them to be more effective, so we may try to use them again in the future.
