A New Small KONDO Servo, KRS-3301 ICS, Put on the Market (Aug 3, 2016)

KONDO KAGAKU CO. LTD. announced a new small servo, KRS-3301 ICS  put on the market on Aug 3,  2016.

KRS-3301 ICS is a small servo of cube type design, the same size of KRS-3304 ICS.  The servo is using a coreless motor and the output maximum torque is 6.0 kgf・cm (7.4 V) of the standard-class with the mini-servo.  Resinous gears are adopted to move the servo smooth and noiseless when the servos are used in the biped robot.

The servo ships out the beginning of Aug, 2016 and is gotten from KONDO web shop or robot shops

Specifications are as follows:
Torque: 6.0 kgf・cm, Speed 0.14s/60° (7.4V)
Torque: 4.9 kgf・cm, Speed 0.16s/60° (6.0V)
Length: 32.5(H) ×26(W) × 26(D) mm
Weight: 26.4 g (excluding cable and servo-horn)
Maximum movement angle: 270° (+-135°)
Gear kind: Resin gear
Case materials: Resin
Gear ratio: 269.92:1
Power supply voltage: 6-7.4V
Cable: Detachable, 300 mm
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 3,800 yen (Excluding tax)
           Six servos package is  19,800 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-3304 ICS on the market late in Feb, 2015.   The servo is a small one of the cube type design.  The details were described in this blog.
