Trial of Survival Game with Multi-Legged Robots in Kichijyoji, Tokyo ( April 10, 2010)

Trial of survival game with multi-legged robots took place at the office of Dai-nihon-giken in Kichijyoji, Tokyo on April 10, 2010. Twelve members join the group of survival game with multi-legged robots. They are almost biped robot builders around Tokyo.

The organizer who are Tanaka , (Dai-nihon-giken) and Bishii , (Asakusa-giken) declared `the 1st Kanto Robot War` on Dec 4th, 2009. They announced that they began to make multi-legged robots with toy-gun and sensor for detecting the impact, which were controlled using image monitor as`Remo`. The movement of making multi-legged robot in Japan began from this announce. The multi-legged robot competition will take place during the 6th KHR Anniversary sponsored by KONDO Co. Ltd. in Asakusa, Tokyo on June 5th, 2010. Multi-legged robots will compete with their ability by the demonstration.

The main regulations of robot survival game are as follows;
1) Mobile bodies are not only multi-legged robot but also with wheel.
2) Weapons are toy-gun under 0.1 J and/or the other shooting system.
3) Equipped stopping mechanism of the body by gunshot sensor using a solar battery.
4) Robot control has to be done with the image on PC from the camera attached on the robot.
5) Members have to handle toy-gun carefully and put protector on eyes.

Ten members and 9 mobile bodies joined the trial meeting. There were 5 bodies with full equipments for the regulation. The other members were in the course of making equipments for the survival game. The purpose of meeting was also for exchanging opinions of the survival game system.

Multi-legged robots and builders attended were as follows;
`Cocktail’ with 4 legs and one tail is custom-built by Momiji. It has no equipments.
`BT (BLACK TIGER) L45` with 5 legs is custom-built by IKETOMU. As it is based biped robot body and using high powered servo motors, the mobility of it is high compared with other multi-legged ones. It has no equipments yet.
`Denryu’ with 4 wheel body is custom-built by Gons. It has full equipments.
`GAN-DOLLA` is modified radio control tank by Koizumi. It has just sensor.
`HILDOLFR-2` is modified radio control tank by Bishii. It has full equipments.
`Hinogazuchi` with 6 legs is custom-built by Tanaka. It also has full equipments.
`10-shiki Kohana-kai’ with 6 legs is custom-built by Gunso-san. It has just sensor.
`Siguma` with 6 legs is custom-built by Shimaken, who is the first builder of multi-lagged robot among biped robot builders. It also has full equipments.
`Vanga` with 6 legs and wheels is custom-built by Igaa. It can move very fast using wheel system. It has full 3 equipments such as gun, sensor and camera.

Three trial survival games and other tests took place. The 1st trial was carried out using camera image on PC in order to examine camera system. `Denryu’, `GAN-DOLLA`, `HILDOLFR-2`, `Hinogazuchi`, `Siguma`, `10-shiki Torahana-kai`, joined the trial. The video was as follows;

The 2nd trial was carried out without camera. `Denryu’, `GAN-DOLLA`, `HILDOLFR-2`, `Hinogazuchi`, `10-shiki Torahana-kai`, `Siguma` and `Vanga` joined the trial. The video was as follows;

The 3rd trial was carried out for the gunshot sensors using a solar battery and following body stopping system. As the result, the stopping system of `Vanga` worked within 1 min. On the other hand, the stopping system of Sigma did not work. It seemed that sensitivity of each sensor depend on the tension of aluminum cover over the solar battery. The video was as follows;

Examination of walking up slope was also carried out. `Siguma`, `Vanga`, `BT-L45 `and `10-shiki Torahana-kai` tried. The video was as follows;

Moving test of BT (BLACK TIGER)-L45 was also carried out in the game field. BT-L45 could move fast every direction. BT-L45 could also move at gallop. The video was as follows;

The details are also described Tanaka's Blog.

The sencond trials of Robot Survival Game also took place at Kanto-Gumi Robot Meeting in Minami-Senju, Tokyo on April 18, 2010. The videos were uploaded to Sanzai's Blog.
