For the past summer i have been thinking about what would help my team while bring at the competition.
In order to help my team my friends and I have developed a concept of "Cart is Pit". Meaning that the cart will house must of all the tools/supplies that are usually in the pit. So when you go down to the floor if you need a tool it would be with your robot before and after the rounds and their would be no need for fetchers.
Carts basic components:
Electrical

I had design this system to have the robot batteries being charged on the cart at all times even when your not near a Ac power source. To go along with that it provides a AC and DC lines for charging laptops and running some electrical tools depending on cart battery size and inverter being used.
Safety
spare glasses, ear plugs, fire extinguisher, and first aid kit.
Tools
all necessary tools for the robot with the addition of some that others may be use if room is present.
Supplies
Spare electronics material
pre made parts
pneumatics stuff
Programing
Computers would have a multipurpose port that will allow the programmer to program their robot and not be next to it. (on the controller is prog and reset pins that would be in the cable to the programmer's station allowing him to control things with out getting in the way of the mechanical team).
Air
Built in large tank that will be full all the time.
robot pressure will be equalized with this tank then pumped independently allowing for a quick pump.
air could also be used in cleaning off dusk and etc.
If all this could be done then your 10x10 foot pit would have more room making it safer. Also everything you would need would be with the robot except for big tools such as mills and etc.
Please post more ideas, however don't say anything about a sound system because FIRST has ruled against it.
More Ideas
The last question is if all this is legal or illegal
