Robot competition, "U1K, Under 1 Kg“ sponsored by RT Co., Ltd. was carried out at RT Office in Akihabara, Tokyo on Jan. 18th, 2009. While the ROBO-ONE humanoids have set the standard for 2 kg at the 15th Championship on May 4th, 2009. Some hobbyist just don’t have the space, resources, or budget to get actively into building large robots. To expand the playing field, RT Co., Ltd. planed an under 1 kg biped robot competition. The regulation of biped robot body are as follows;
Weight: under 1 kg, Height: under 60 cm, Total axis: more than 15 ( arm with 6 servos, foot with 8 servos ), Sole size of foot: under 12 cm, Max wide length: under 60 cm, Robot control: wire, radio, IR control or autonomous.

The rule of the game `Pylon Attack` are follows; Field Size: 90 cm square, located 4 cubes along the center line. Robot puts off the rival’s pylon out of the field is winner. Robot gone down from the field is loser. Robots could attack each other and knocking down is not related to winning or losing of the game.

Twelve robots attended the competition. As marketed robots, i-SOBOT or G-ROBOT are fitting the body regulation, 3 i-SOBOTs and 2 G-ROBOTs attended the competition. However i-SOBOT is too small to compete other original robots or G-ROBOTs, competition for just i-SOBOT was also carried out.

The winner was Demo-5(UEMURA), G-ROBOT. G-ROBOT was marketed on March 2007 by HPI JAPAN. Its weight ( 900 g ) and movement activity are just suitable for U1k. The second place was Soga (IGAA), original robot developed for battle using small size servo by Mr. Igaa who developed Saga. In the i-SOBOT competition, KENTA-ki (KENTA) was winner.
