KRS3304 ICS, a new small KONDO servo put on the market (Feb 9, 2015)

KONDO KAGAKU CO. LTD. announced a new small servo, KRS-3304 ICS  put on the market on Feb 9, 2015.
KRS-3304 ICS is a small servo of cube type design. The servo is using a coreless motor and the output maximum torque is 13.9 kgf・cm (7.4V time) of the top-class with the mini-servo.  Metal gears are adopted to secure the durability when the servos are used in biped robot.

The servo ships out on Feb 9, 2105 and is gotten from KONDO web shop or robot shops

Specifications are as follows:
Torque: 13.9 kgf・cm, Speed 0.11s/60° (7.4V)
Torque: 11.2 kgf・cm, Speed 0.13s/60° (6.0V)
Length: 32.5(H) ×26(W) × 26(D) mm
Weight: 33.7 g (excluding cable and servo-horn)
Maximum movement angle: 270° (+-135°)
Gear kind: Metal gear
Case materials: Resin
Gear ratio: 289.22:1
Power supply voltage: 6-7.4V
Cable: Detachable
Cable head: 350 mm (black cable)
Connector: ZH Connector
Communication standard: ICS3.5 (Serial /PWM choice type)
Communication Speed: 115200/625000/1250000bps
Controller: RCB-3HV, RCB-4HV, KCB-5 and RCB-3J(PWM only)
Price: One servo package is 8,800 yen (Excluding tax)
           Six servos package is 46,800 yen (Excluding tax)
           Eighteen servos package is 122,400 yen (Excluding tax)

Attentions for using this servo are as follows:
※This product is a servo for 6-7.4V.  It does not support battery for HV.
※The cable is detachable.
※When you use it by Ni-MH5 cell (6V), the combination of RCB-4HV/3HV and Li-Fe2 cell (6.6V), please use booster 3 (voltage up circuit).  In the case of the use, it is not particularly necessary in Li-Po2 cell (7.4V).
※The initial setting is PWM mode. When you use it with a serial number, you use Dual USB adapter HS or ICS USB adapter HS and ICS manager software, and please set mode reshuffling and the ID number. Because it is PWM mode at the time of the shipment, even the microcomputer board of other companies is just connected and is available.

KONDO KAGAKU CO. LTD. also put a new small servo, KRS-3204 ICS on the market late in October, 2014.   KRS-3204 ICS is a small servo of the standard type design.  The details were described in this blog.

The 10th TIROL-CHOCO Robot Competition in Akihabara, Tokyo (Feb 14, 2015)


The 10th TIROL-CHOCO Robot Competition , sponsored by MASAYUKI-san, supported by RT Co., Ltd. and cooperated by TIROL-CHOCO CO., took place at Akihabara Robot Aisle, Tokyo on Feb. 14, 2015.   The competition is for robots with TIROL-CHOCO exterior. The 1st competition was held on July 9, 2007. After that, the completion took place every year.

Regulation of robot body was as follows;
1) Robot had to put on big TIROL-CHOCO exterior, which size were bottom (100 mm x 100 mm), upper surface (86 mm x 86 mm) and height (46 mm) respectively.
2) Biped robot. Number of servo for legs was under 4. Total number of servo was not limited.
3) Control method such as autonomous, radio and wired was free.
For UK1 (Under 1 kg) Robot
1) UK1(Under 1kg) robot passed recently UK1 regulation also can join the competition.
2) Robot had to put on big TIROL-CHOCO exterior, which size were bottom (100 mm x 100 mm), upper surface (86 mm x 86 mm) and height (46 mm) respectively.
Each both type robot had to prepare a basket within 60 mm diameter and free height.
TIROL- CHOCO Robots also have a handicap in playing time campered with UK1 Robots.

The competition was consisted with three kinds of game as follows.  Each robot gets points depended on the order of each game.

(1) Foot Race
Robot walks the course within 3 minutes. The order is depended on the time. If robot cannot walk the course within 3 minutes, the order is depended on the distance from the start line.  Each robot can try twice and the best time is recorded.   Videos of nine robots Foot Race are as follows;

(2) TIROL-CHOCO Shooting
Three paper cups with TIROL-CHOCO on the top put on the field.  Robot shoots the paper cups from oposite side for 5 minutes. Robot gets dropped TIROL-CHOCO from the top of paper cup. The order is depended on the number of shot TIROL-CHOCO. Videoe of nine robots TIROL-CHOCO Shooing are as follows;

(3) TIROL-CHOCO Carrying Race
The field divided 15 small parts which numbered 1, 2, 3, 4, 5, 6.  When robot walks through the number, player puts the number of TIROL-CHOCOs into the basket on the robot, then robot goes back to the start place.  The order is depended on the time and the number of TIROL-CHOCO carried within 5 minutes.  Videos of nine robots TIROL-CHOCO Carrying Race are as follows;

After the 3 games, the winner is the robot gotten the most total points of game.  Nine Robots joined were 1) Z-Tiromon (TIROL) by Moto-Iincho, 2) Garukid (UK1) by Kumama, 3) Zemunes (UK1) by Nigagawa, 4) Shaoron (UK1) by Koizumi, 5) Teruru (UK1) by A4, 6) Bosa-2 (TIROL) by Masaharu Mukoyama, 7) Proto-Trolin (TIROL) by Sugar, 8) Tirolia-1 (TIROL) by Ikki Saito, 9) BT-R3HV (TIROL) by IKETOMU.

1) Z-Tiromon
 2) Garukid
 3) Zemunes
 4) Shaoron
 5) Teruru
  6) Bosa-2
7) Proto-Trolin 
 8) Tirolia-1
 9) BT-R3HV
The winner robot of TIROL-CHOCO 10th was Teruru by A4, the 2nd place was Z-Tiromon by Motoiincho and the 3rd place was Garukid by Kumama.  BT-R3H was the 4th place.  Zemunes got Elegant Prize which obtained votes the most by players attended.

The 4th TIROL-CHOCO Robot Competition on Feb 13, 2010 and  the 9th Competition on Apr 26, 2014 were described in this blog.
