Race winner Robovie PC wears his heart on his sleeve, so to speak.

The word's first bipedal robot marathon wrapped up in Osaka, Japan, over the weekend with a 15-inch droid taking home the prize after a near photo finish.

Dramatic finish: Robovie-PC breaks the tape.

Team Vstone's Robovie-PC won the Robomarafull race in 54 hours, 57 minutes, and 50 seconds, with Robot Center Team's Robovie-PC Lite nipping at his heels and crossing the finish line just a second behind.

The other three robo-runners, including two from Osaka Institute of Technology, had dropped out of the 26.2-mile endurance contest, which was organized by robot maker Vstone and the Osaka government.

Winner Robovie-PC is a high-end kit robot with 20 moving joints and weighing about 5 pounds. It ran the race autonomously by following colored tape on the track.

Powered by a 1.6GHz Intel Atom Z530 microprocessor, it has a head camera and urethane sponge foam on its exterior to protect it from falls.

Vstone sells the Robovie-PC kit starting at about $4,890.
