Linux-Based Robot To Explore The Forest
crashoverride025 contributes this link to a BBC story about Treebot, "A Linux-based mobile robot equipped with a webcam and sensors swings into action to help monitor forests." Despite the Tarzan reference, it looks like this robot moves along a cable, rather than swinging from place to place.
But this has actually been done before according to a Yahoo! News article from early this year. And yes, this is actually a different project, not the same one from the article.
