HTH4 (HeartToHeart4) is used to adjust the robot. The software is exclusively for RCB-4HV/RCB-4mini
(referred to as “RCB-4” below) and has been designed to make it easy for anyone to control the robot.
Using this software allows you to make full use of the functions needed to freely operate the robot,
including the neutral position check (checks that parts have been assembled correctly with the servos
in the origin (neutral) position), basic positioning adjustment (trim adjustment), motion creation, sensor
settings, etc.
■ Install HeartToHeart4 Software
To install the software, double-click the "setup.exe" in the HeartToHeart4 folder in the CD-ROM
included with the kit to automatically run the setup program. Continue the installation process as
instructed by the setup program.
1. Software Installation
After completing the software installation, click the “HeartToHeart4” icon in the Windows Start Menu
or on the Desktop to run the software.
When running HeartToHeart4 for the first time, a HeartToHeart4 folder is created in the My Document
folder of your personal computer. Project files created must be saved in the “Projects" sub-folder in
this folder.
2. Software Activation
Connect the Serial Extension Cable to the Dual USB Adapter HS, and connect the other end to the
port connector at the top of the KXR backpack.

the kit and included CD-ROM.
When the power is turned on, all the servos will light up and then some of the
servos will go out. The remaining servos will be lit up somewhat dimly. The robot
will not move until you load the project (motion data) and run it, but this is its
normal state.
*Servos with LEDs that turn on and off differ depending on the servo layout of the project example.
