Telepresence robots let employees 'beam' into work - Article Photos 3/6

Engineer Christian Carlberg tests the Beam, a remote presence system, through an obstacle course at Suitable Technologies in Palo Alto, Calif., Wednesday, Dec. 12, 2012. More employees are working from home, but there's still no substitute for actually being at the office. Enter the Beam. It's a roving computer screen _ with video cameras, microphones and speakers _ that stands five feet and rides on motorized wheels. (AP Photo/Marcio Jose Sanchez)
