Limited 100 black colored robots will be sold. The price is 114,000 yen excluding tax. Just body color, flame and plastic parts color are changed from light blue to black but specifications such as control board and servos are the same those of original KHR-3HV which was put on the market in 2009.
Black colored plastic parts for KHR-3HV also will put be on the market at the same time. KHR-3HV black parts set is 4,500 yen excluding tax.
Black colored robot seems to be cool and black color fits to robots because most of servo color are black. I changed KHR-1 body and flame color from aluminum color to black for making reviced robot BLACK TIGER. My custum-built biped robot, BLACK TIGER NEO and custum-built anomalous 5-legged robot, BLACK TIGER L45 were also colored black.
KONDO CUP, Robot Soccer Gamestarted on June 5th, 2006. Almost every 2 month, KONDO Co. Ltd. held the games at ROBOSPOT. There are two classes, one is KHR Class which KHR-series robot such as KHR-1, 1HV, 2HV, 3HV can attend the games. KHR robots changed 4 and less than 4 high-torque servos such as KRS-4013HV, KRS-4014HV, KRS-2350HV also attend the KHR Class game. The other class, Open Class in which robots using just KONDO servo motor can attend the game and the number of high-torque servo is not limited.
In the 23rd Open Class preriminary league, the first half was 3 minutes, halftime 1 min and the second half was 3 mins. In the final game, the first half was 5 mins, halftime 1 min and the second half was 5 mins. One team was consisted with 3 or 4 robots. Just 3 robots could play soccer in the field. The soccer field of Open Class was larger than that of KHR Class. The regulation of robot body and rules of soccer are described in the KONDO’ s web site.
Five teams joined Open Class on Dec 5th had a preliminary league. Teams joined were Team Shisenkai, RFC Bamboobridge, Speed☆Stars, Kanto-Branch and RoboDouraku. My Custum-bulit robot, BLACK TIGER NEO also joined Kantou-Branch as NagareBlackTiger. Kantou-Branch members were Ryuketsukamen, NagareGold and NagareBlackTiger.

In the interval of the preliminary League, Trial Game of Animal Class took place with 6 robots. KONDO is planning to begin of KONDO CUP Animal Class for multi-legged robots in the next year.
The 3rd Robot Survival Game took place for 2 days at Make: Tokyo Meeting 06. Tanaka-san and other members demonstrated some kind of survival game and also exhibited robots and mobiles with gun and sensor systems of Robot Survival Game at the exhibition room.
It is not so hard to make a survival game multi-legged robot for robot builders who have been making biped custom-built robots. Because they have a lot of idle controller, servos, arms and parts.
However, it is hard for a beginner to make a survival game robot system, especially to make a multi-legged robot. It costs much money to make a multi-legged robot. Tanaka-san made a custom-built 6-legged robot, Hinogazuchi with survival game system. He calculated the budget for a standard robot survival game system which is consisted with robot (or mobile), camera, gun and hit sensor, which costs about 187,000 yen as follows.
Standard Robot Survival Game System [Robot]
Control Board (RCB-3HV): 17,000 yen
Servo Motor (KRS-788HV): 6000 x 20 = 120,000 yen
Flame Parts: 10,000 yen
Battery: 3000 yen
Radio Control Transmitter & Receiver (KRC-2AD): 18,000 [Gun]
Mini Electric Air Gun: 3000 yen [Camera]
USB Wireless Web Camera: 8000 yen [Hit Sensor]
Hit Sensor Parts: 3000 yen
Others: 5000 yen Total Cost: 187,000 yen
The robot survival game system is consisted with 4 elements such as robot or mobile, camera, gun, hit sensor. The most expensive element is robot system including radio control system and battery which costs 168,000 (90%) in the standard system.
Tanaka-san planned to use a mobile kit with radio control system on the market such as Gunroller or R/C Scraper which cost about 3000 or 4000 yen including radio control system. It is the reason why the robot survival game permits to join not only robot but also mobiles such as tank with 4-wheels or caterpillars. The total of using Gunroller survival game system costs 18,000 yen.
Using Gunroller survival game system
Gunroller: 3000 yen
Mini Electric Air Gun: 3000 yen
USB Wireless Web Camera: 8000 yen
Hit Sensor Parts: 3000 yen
Others: 1000 yen Total Cost: 18,000 yen
Using low price robot make the robot survival game system cheapper. Noborizaka-san also made a survival game robot system using 4-legged turtle robot which was put on the market by KONDO. The price of the turtle robot is 39,900 yen (including tax and excluding radio control system).
I also tried to make 5-legged robot, BT-L15 based KHR-1. The mobility of the robot was superior to those of multi-legged robots. Now KHR-1 was not put on the market but KHR-2 HV which is 90,700 yen (excluding tax, excluding radio control system), is put on the market, can be used as the base of 5-legged robot.
I have been enjoying biped robot since 2004, when KHR-1 was put on the market, and collecting information of hobby robots. I would like to upload information about hobby robots in Japan for the hobbyists of biped robot all over the world. As my ability for uploading is limitted, I will introduce just news of product, kit or parts and information of competition etc. with picutures or videos.
