BURNS (AP) — Robot boats are set to sail this summer on Malheur Lake. But the high-tech tools won’t be used right away to find the non-native carp infesting the lake, as refuge managers had hoped. The summertime study will be more about field testing the boats than searching for the fish, said Peter Sorensen, a professor at the University of Minnesota. The experimental, 6-foot-long robotic crafts that resemble toy boats are being tested in smaller lakes around Minnesota. Before they launch the craft on Malheur Lake near Burns, Ore., Sorensen said researchers are perfecting the design in the $2.2 million study funded by the National Science Foundation.March 19, 2013 2 p.m. read more..
