In this Oct. 22, 2012 photo, Google operations manager Steve Silverman walks with the Trekker during a demonstration for the media along the Bright Angel Trail at the South Rim of the Grand Canyon National Park in Arizona. The search engine giant is using the nearly 40-pound, backpack-sized camera unit to showcase the Grand Canyon’s most popular hiking trails on the South Rim and other off-road sites. It’s about 4 feet in height when set on the ground, and when worn, the camera system extends 2 feet above the operator’s shoulders. (AP Photo/Rick Bowmer)
