Frois, the groom, and bride Yukirin walked the aisle, wore traditional outfits and even carried out a 'wedding kiss' at the event in Tokyo on Saturday.
Special invitations were made, featuring a picture of the two robots inset in a heart, and the 100-strong congregation included a range of smaller robotic models.
After the ceremony the couple even managed to 'cut a cake' before an automated orchestra performed a song for the equivalent of their first dance.
The event was organised by Maywa Denki, which produces electronic accessories and designed the groom Frois.
