Servo motors are integrated with gears for raising the output torque and a control board that enables stopping at any angle.
Using servo motors in the robot’s joints makes it easy to send angle commands to the joints and enables multiple motors to be
accurately controlled at the same time. The KRS-3301 ICS servo used in this kit employs half-duplex serial communication, so
operating commands can be sent simultaneously to multiple servos, and this allows cables to be wired using the multi-drop/dai-
sy-chain method (method for connecting servos like a chain of beads). This reduces the number of cables connected to the
control board to make possible a simpler, cleaner layout. You can also easily upgrade to the higher-grade KRS-3304 ICS for
more powerful operating performance.
The RCB-4mini control board used in this kit has a total of six ports, three
SIO (serial) ports for each of two systems of ICS3.0/3.5/3.6 compliant
devices, and can connect up to 36 ICS3.0/3.5/3.6 devices.
There are also five AD (analog) ports, so gyro/acceleration and other analog
sensors can be used.
High-speed, high-capacity EEPROM has been adopted to make it possible
to run multiple, varied motions."
