Aloha,
We have built a custom cart this year to ship with our robot.
It is setup with drawers for tools, spare parts bins, storage area for the bumpers and team swag. One side has a flat screen tv and dvd player to run our promotional videos and the like. The otherside has a fold out table and white board to go over stratagies with. We have a robot battery storage area with chargers for each stored battery. All of this is set up to run off car batteries with an inverter. It also has a A/C connection to run when not mobile. This also charges the car batteries.
There are some more features that I am sure I am missing, like the fact it secures the robot for shipping and of course carts the robot around safely. We managed to finish painting and polishing it before stop build day.
This has surely helped us keep from traveling with a bunch of tools and spare parts in the luggage!
We will be at the Los Angeles, Inland Empire and Hawaii regionals, come by and take a look if you are able.
Any questions let me know...
Good luck to everyone!
