Here's another cool autonomous vehicle project on Kickstarter. Pledge $400 or more and, if the project hits its funding goal, "We send you a remotely controlled 1m (3.2ft) long, articulated, inflatable Protei in KIT to assemble yourself. The design and functionalities would be similar to the one of Protei002 (http://goo.gl/dWG7p)."
"We are developing Protei : a low-cost open-source oil collecting robot that autonomously sails upwind, intercepting oil sheens going downwind. Protei combines conventional technologies in an innovative design that we can implement in the short term to address timely environmental crisis such as the BP Oil Spill, cleaning the ocean gyre garbage patches or performing ocean research. We need your help to build our next prototype of Protei - the first articulated sailing boat that can tack upwind pulling a long heavy payload and initiating a revolutionary family in ocean robotics. http://protei.org"
