KHR 3HV Humanoid Robot Kit
Robosavvy is Offering the
KRI-3 Interface Board for FREE to all customers who purchase a KHR
3HV.
If you have purchased a KHR 3HV and would like to to obtain the English Documentation for the Robot, please contact sales@robosavvy.com. |
During its 5th Anniversary (June 13th 2009), Kondo Kagaku has released the
brand new KHR-3HV.
A new design, a new frame, new servo interface, much more DOF, a new stylish
robot that will dramatically change once more the robot hobby market.
 |
A tall, extensible KHR
The base robot includes 17 servos (DOF) + 5 Dummy servos that allow for
easy expansion up to 22 DOF. The robot is assembled from the
start with the 22 servos in place (17+5), a feature unique in the
Humanoid market.
The dummy servos can be progressively replaced with real servos to make
for up to 22 DOF.
The long arms and legs (achieved with the use of
22 servos) make for the tallest KHR ever, with an exceptional
performance.
Another advantage of using 22 servo cases from the beginning is that all
gaits you develop and create will still perform sucessfully as you
upgrade to 22 DOF.

RCB-4HV and ICS 3.0
The new micro controller board RCB-4 enables the control of up to 35
serial servos.
It is compatible with ICS3.0 (serial) servo protocol and a wide
range of options parts.
The board also includes several extension ports (10x A/D and 10x PIO)
which enable the use of a wide range of sensors and extension options.KHR 3HV uses KRS-2555HV servos, the first Kondo servo to use ICS 3.0. The
use of a serial protocol
allows the connection of several servos in a Daisy chain.
By connecting in a Daisy chain the number of cables is very reduce and
therefore prevents troubles regarding disconnection and improves cable
routing. KRS-2555HV Servo Specs:
- Maximum Operating Angle 270º
- Maximum Holding Torque 14kgf.cm (11.1V)
- Speed 0.14s/60º (11.1V, under no load)
- Size 41x21x30.55 mm
- Weight 41.5g
- Operating Voltage 9V~12V
The new servo is slightly smaller than KHR-2HV servos and offers
increased torque and operating angles.
The use of metal gears improves servo reliability and strength.
ICS 3.0 servos operate at 1.25Mbps standard for fast communication
but may be adjusted for lower speeds.

New Frame
A design to ease and to smooth the folding of the knee has been enhanced.
Thanks to the new design, the robot can retract and stand up faster from
a sitting pose.
The use of materials such as aluminium, polycarbonate and ABS with
incorporation of Glass allow for lighter yet robust frames.
|
 |
Improved Angles and Servo Arms
Thanks to the strengthened servo arms, the robot is more resistant to
shocks and thus become a real ally during robot competitions.
|
| |
Body Cover
The main frame cover is made out a light ABS plastic. It is easy to
change to another body frame for customization and modding.
Thanks to the slim body, the user can handle the robot more easily.
|
 |
Dummy Servos
The robot comes fitted with five dummy servos in strategic places for
extension (chest/torso, arms) and is assembled with these static servos
in place for the first minute to build the robot's tall and slim figure.
You simply need to replace the dummy servo with the optionally available
KRS-2552HV servos for added DOF.
This new faculty enables the user to easily add new degrees of freedom
and set up new capabilities for the robot.
|
| |
Servo Head
The new design of the servo head makes it possible to assemble it
naturally to the shoulder. It is meant to give the robot a more
intrepid style.
|
 |
Bath tub Sole
The new design of the sole gives a more secure walk.
|
 |
Maintenance
The new design of the back pack enables an easier maintenance of the
robot. The user will be able to easily add sensors and motors.
|
 |
Battery
A nickel battery 10.8V-800mAh has been included.
With the "fast charger" included the battery takes only one hour to
charge.
|
 |
New Software - Heart to Heart 4
Heart to Heart software has been upgraded to version 4 and now includes
new motions and a new type of programming.
The new software also includes "project management" features for
improved collaboration and performance in team competitions.

Optional Accessories:
KHR 3HV is backwards compatible with most of Kondo accessories for
previous KHR editions:
- The KRI-3 Interface Board was designed to interface KHR 3HV with
Remote Controllers from Kondo. It enables the connection and use of
KRC3-AD and other radio units to the new RCB-4HV.
Robosavvy is currently offering the KRI-3 Interface Board for
free with the first purchases of KHR 3HV.
- RAS-2, KRG-3 and KRG-4 are also compatible with KHR 3HV and are
recommended sensors for this robot.
- A new ICS USB Adapter HS is now available for
communication with the servos. The difference from the previous
version resides in the maximum speed of the communication.
The HS version is backwards compatible with other Kondo servos.
( The ICS USB adapter HS is included in the Standard KHR 3HV kit. )
- Additional KRS-2555HV servos can be added to the robot (to
replace the dummy servos) to extend it from 17 DOF progressively up
to 22 DOF.
