from the long-row-to-hoe dept. [article] Solar powered robot uses GPS for navigation, has two small cameras mounted on a frame on top of the machine to give the robot depth perception. "If he sees a weed, he can actually tell how far away it is," said Lei Tian, agricultural engineer at University of Illinois. On-board computer offers access to information that provides the morphological features of plants, to help the robot determine just what is and isn't a weed. Once a weed is identified, a robotic arm attached to the front of the machine engages a device the researcher calls "a custom-designed end effector." With its level of precision the system has environmental benefits by cutting herbicide use and the chemicals do not drift off-target when placed directly on the plants. http://www.eurekalert.org/pub_releases/2006-10/uoia-oi101006.php < Researchers discover mechanism that determines when detailed memories are retained | Hidden fertility belief is challenged: humans display with behavioral changes >
