Product Description

KRS-3204 ICS is a small servo of standard type design. Since this servo employs a high output coreless motor, it outputs a maximum torque of  9.3kgf · cm (at 7.4 V). To secure the durability when using it with a biped walking robot, we adopted a metal gear.

 

 

[Product Specifications]

Gear: Metal gear
Since all gears are metal, it has sufficient durability.
By supporting the shaft of the final gear with a bearing, stable operation has been realized.


Case: KRS 3200 Series

The case of KRS - 3200 series is thin, easy to secure the movable range.

 

Communication specifications: ICS3.5
Communication uses ICS3.5, which allows you to select between serial and PWM. Servo motor communication can be changed based on the microcomputer board used for control.
Also, in serial mode, with serial and PWM, IDs can be assigned to the servo motors, so multi-drop connection in which the servo motors are connected is possible. A red LED light indicating the communication status is mounted on the main unit. ICS3.5 allows you to change various items like the servo motor’s operating speed and retention characteristics. For details, refer to the following.
* Servo motor settings require Dual USB Adaptor HS or ICS USB Adaptor HS.

[Cautions]

*The product is a 6-7.4V servo motor. HV batteries cannot be used.

*When used in combination with RCB-4HV/3HV and Ni-MH5 cells (6V) or Li Fe2 cells (6.6V), use Booster 3.1 (booster circuit). When Li Po2 cells (7.4V) are used, this is not necessary. It also is not necessary with RCB 4mini.

*The communication mode at shipment is Normal Mode, so you can switch between serial mode and PWM mode depending on the high/low of the signal wire after powering up.When used with RCB4, it is automatically recognized to be in serial mode. Use the product after assigning it to a servo motor ID number. For details on communication specifications, refer to the Software Manual.
When used with serial-only (PWM prohibited), switch using the Dual USB Adaptor HS sold separately.

    About KRS Servo Motor Communication Modes

*For the securing screws on the free horn side, use a 2.6-4 flat head screw. If a 2.6-6 flat head screw (included with KHR-3HV, etc) is used, they may pierce the case and break the base.

*To secure the frame to the upper case, use 2 mm screws.

 

 

[Power supply]

For LV servo, please use 2 cell (6.6 V) lithium ferrite battery(Li-Fe).

  ROBO Power Cell F2-850 type (Li-Fe)

  ROBO Power Cell F2-1450 type (Li-Fe)

*Handling the battery requires caution.Please read this article before using.

 

6-cell (7.2 V) battery of Ni-MH can also be used.

*BX-31LF / 32MH can not be charged from the PC's USB terminal. Please do not connect charger to PC. Please use the AC adapter (2A recommended) to be used for charging the smartphone etc.

 

AC Adapter

For robots with fewer servos mounted like arm type, you can use the following AC adapter. Be careful of the current capacity when using it.
