We (Team 330-Beach Bot) have located a transportation company that trucks to Phoenix and will charge about $100 for the transportation of the crated robots from LA to Phoenix. The price may vary due to pick-up location, but give them a call if you are still looking to ship your robot. Call Synergy Cargo at 310-370-1887 and ask for Richard the shipping supervisor to get the price quote for your team. They are located in Torrance. We have not used them before, so we are making no endorsement, but they certainly seem easy to work with!
Good luck
Tom Freitag
