A robot sits before Buddhist monks, as they pray during a mass alms-offering ceremony at King Mongkut's Institute of Technology Ladkrabang in Bangkok, on June 19, 2012. The ceremony was held to mark the 2,600th anniversary of the enlightenment of Lord Buddha.
The robot "Obelix" runs through Freiburg city center, on August 21, 2012. The machine, starting 9:45 in the morning at the University of Freiburg, found its way independently to a plaza in the center of Freiburg, about four kilometers away. Obelix made the journey, avoiding people and obstacles, in about 100 minutes.
